DYSURIA:
DIAGNOSTIC WORKUP
(Algorithmic Diagnosis of Symptoms and Signs)
Obviously, a urinalysis and Gram stain of the unspun urine should be done in all cases. If this is positive, treatment can be initiated. Urine cultures are only necessary for resistant or repeated episodes. I also recommend a urethral smear and a vaginal smear and culture if sufficient material can be obtained. This may mean massaging the prostate for an adequate specimen. Even four white cells per high-powered field on a urethral smear probably indicates urethritis. Cultures for both gonorrhea and chlamydia should be done. In persistent cases of dysuria, an intravenous pyelogram and a cystoscopy must be done. A urologist needs to be consulted before ordering these tests. Blood cultures should be done in cases of acute pyelonephritis. Cultures for anaerobic bacilli and tuberculosis may be necessary in persistent pyuria. It should go without saying that a rectal and vaginal examination should be done in all cases. However, this is frequently neglected.

NOCTURIA:
DIAGNOSTIC WORKUP
(Algorithmic Diagnosis of Symptoms and Signs)
Routine laboratory tests should include a CBC, sedimentation rate, urinalysis, chemistry panel, and urine culture and sensitivity. A quantitative 24-hr urine volume should be determined. If this is above normal, the differential diagnosis of polyuria should be considered and additional workup can be found on
page 372
.
Catheterization for residual urine will help determine if there is bladder neck obstruction. If congestive heart failure is suspected, a chest x-ray, EKG, and venous pressure and circulation time should be done. For further evaluation, a nephrologist or urologist may be consulted.

POLYURIA:
DIAGNOSTIC WORKUP
(Algorithmic Diagnosis of Symptoms and Signs)
Routine tests include a CBC, sedimentation rate, urinalysis, urine culture and colony count, chemistry panel, thyroid panel, and x-rays of the skull and long bones. The 24-hr intake and output should be measured. A serum and urine osmolality will be helpful, as would a spot urine sodium.
If pituitary diabetes insipidus is suspected, a CT scan of the brain and tests for pituitary hormones should be done. The intake and output before and after Pitressin® may be measured.
If renal disease is suspected, the urinary sediment should be examined microscopically and renal biopsy may be necessary. An endocrinologist and nephrologist should be consulted before undertaking expensive diagnostic tests.

PROTEINURIA:
DIAGNOSTIC WORKUP
(Algorithmic Diagnosis of Symptoms and Signs)
When faced with a report of protein in the urine, the first thing to do is look at the urine under the microscope. If there are significant numbers of bacteria and WBCs, one has only to order a urine culture and colony count and begin therapy. Recurrent UTIs warrant an IVP and a referral to a urologist, especially in males. If no infection is found, a more thorough workup is warranted, including CBC, chemistry panel, serum protein electrophoresis, ANA, sedimentation rate, urine for Bence-Jones protein, Addis count, ASO titer, IVP, and CT scan of the abdomen. A urologist may need to be consulted for cystoscopy and retrograde pyelography. A nephrologist may need to be consulted for renal biopsy and further evaluation.

DIFFICULTY URINATING:
DIAGNOSTIC WORKUP
(Algorithmic Diagnosis of Symptoms and Signs)
Routine laboratory tests include a CBC, sedimentation rate, urinalysis, VDRL test, urine culture, colony count, and sensitivity. If there is a urethral discharge, a Gram stain and culture for gonococcus should be done. If this is negative, a culture for chlamydia should be done. The patient should be catheterized for residual urine. Alternatively, ultrasonography may be done to demonstrate residual urine. If there is a significant amount of residual urine, referral to a urologist for cystoscopy and cystometric testing is done.
If there are focal neurologic signs, a neurologist is consulted. An enlarged prostate or a prostate that is nodular should be an indication for a consultation with a urologist and ordering a PSA titer.

FREQUENCY OF URINATION:
DIAGNOSTIC WORKUP
(Algorithmic Diagnosis of Symptoms and Signs)
The first thing to do is a urinalysis and examine the urinary sediment. This will help determine if there is a UTI and if there is diabetes or one of the other causes of polyuria. A sterile sample of the urine should be sent to the lab for culture regardless of whether the urinalysis is normal.
If these studies are unremarkable, a 24-hr urine volume is determined. If the urine volume is substantially increased, the workup may proceed for polyuria . If the 24-hr urine volume is normal, a pelvic and rectal examination must be done for a mass that might be pressing on the bladder. Even if the pelvic and rectal exam is negative, pelvic ultrasound may disclose a pelvic mass.
The next step would be to catheterize for residual urine. If the residual urine is large, bladder neck obstruction is probably the problem, and prostatic hypertrophy, median bar hypertrophy, and urethral stricture must be considered.
Further studies include an intravenous pyelogram, cystogram, cystoscopy, and retrograde pyelography, but these should be done in consultation with a urologist. If a spastic neurogenic bladder is suspected, order cystometric tests and a neurology consult.

INCONTINENCE OF URINE:
DIAGNOSTIC WORKUP
(Algorithmic Diagnosis of Symptoms and Signs)
Routine laboratory tests include a CBC, a urinalysis, a urine culture and sensitivity, a chemistry panel, and a VDRL test. An intravenous pyelogram and a voiding cystogram may be helpful. A Q-tip test or stress test may be helpful in diagnosing stress incontinence. The bladder may be catheterized for residual urine, or abdominal ultrasonography may be employed to evaluate residual urine. Fifty milliliters or more is considered abnormal. Cystoscopy may also be necessary to determine if there is chronic bladder inflammation or bladder neck obstruction. Office cystometrography can be considered, but it is usually best to refer the patient to a urologist for cystometric studies. Prostatic size can be determined by transrectal prostatic ultrasonography.
The simplest and most cost-effective approach is to refer the patient to a neurologist if there are abnormalities on the neurologic examination, or refer the patient to a urologist if there are not. If there is stress incontinence and a cystocele is found on vaginal examination, the patient should be referred to a gynecologist. It is not cost-effective to begin ordering MRIs or CT scans of the brain and spinal cord without the assistance of these specialists.

Urine cloudiness:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
Ask about symptoms of UTI, such as dysuria; urinary urgency or frequency; or pain in the flank, lower back, or suprapubic area. Also ask about recurrent urinary tract infections or recent surgery or treatment involving the urinary tract.
Obtain a urine sample to check for pus or mucus. (See Peforming the three-glass urine test, page 608.) Using a reagent strip, test for blood, glucose, and pH. Palpate the suprapubic area and flanks for tenderness.
If you note cloudy urine in a patient with an indwelling urinary catheter, especially with concurrent fever, remove the catheter immediately (or change it if the patient must have one in place).

Bladder distention:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
If distention isn't severe, begin by reviewing the patient's voiding patterns. Find out the time and amount of the patient's last voiding and the amount of fluid consumed since then. Ask if he has difficulty urinating. Does he use Valsalva's or Credé's maneuver to initiate urination? Does he urinate with urgency or without warning? Is urination painful or irritating? Ask about the force and continuity of his urine stream and whether he feels that his bladder is empty after voiding.
Explore the patient's history of urinary tract obstruction or infections; venereal disease; neurologic, intestinal, or pelvic surgery; lower abdominal or urinary tract trauma; and systemic or neurologic disorders. Note his drug history, including his use of over-the-counter drugs.
Take the patient's vital signs, and percuss and palpate the bladder. (Remember that if the bladder is empty, it can't be palpated through the abdominal wall.) Inspect the urethral meatus, and measure its diameter. Describe the appearance and amount of any discharge. Finally, test for perineal sensation and anal sphincter tone; in male patients, digitally examine the prostate gland.

Nocturia:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
Begin by exploring the history of the patient’s nocturia. When did it begin? How often does it occur? Can the patient identify a specific pattern? Precipitating factors? Also, note the volume of urine voided. Ask the patient about changes in the color, odor, or consistency of his urine. Has the patient changed his usual pattern or volume of fluid intake? Next, explore associated symptoms. Ask about pain or burning on urination, difficulty initiating a urine stream, costovertebral angle (CVA) tenderness, and flank, upper abdominal, or suprapubic pain.
Determine if the patient or his family has a history of renal or urinary tract disorders or endocrine and metabolic diseases, particularly diabetes. Is the patient taking a drug that increases urine output, such as a diuretic, a cardiac glycoside, or an antihypertensive?
Focus your physical examination on palpating and percussing the kidneys, CVA, and bladder. Carefully inspect the urinary meatus. Inspect a urine specimen for color, odor, and the presence of sediment.

Polyuria:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
Because the patient with polyuria is at risk for developing hypovolemia, evaluate his fluid status first. Take his vital signs, noting an increased body temperature, tachycardia, and orthostatic hypotension (a ≥10 mm Hg decrease in systolic blood pressure upon standing and a ≥10 beats/minute increase in heart rate upon standing). Inspect for dry skin and mucous membranes, decreased skin turgor and elasticity, and reduced perspiration. Is the patient unusually tired or thirsty? Has he recently lost more than 5% of his body weight? If you detect these effects of hypovolemia, you’ll need to infuse replacement fluids.
If the patient doesn’t display signs of hypovolemia, explore the frequency and pattern of the polyuria. When did it begin? How long has it lasted? Was it precipitated by a certain event? Ask the patient to describe the pattern and amount of his daily fluid intake. Check for a history of visual deficits, headaches, or head trauma, which may precede diabetes insipidus. Also check for a history of urinary tract obstruction, diabetes mellitus, renal disorders, chronic hypokalemia or hypercalcemia, or psychiatric disorders (past and present). Find out the schedule and dosage of any drugs the patient is taking.
Perform a neurologic examination, noting especially any change in the patient’s level of consciousness. Then palpate the bladder and inspect the urethral meatus. Obtain a urine specimen and check its specific gravity.

Urethral discharge:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
Ask the patient when he first noticed the discharge, and have him describe its color, consistency, and quantity. Does he experience pain or burning on urination? Does he have difficulty initiating a urine stream? Does he experience urinary frequency? Ask the patient about other associated signs and symptoms, such as fever, chills, and perineal fullness. Explore his history for prostate problems, sexually transmitted disease, or urinary tract infection. Ask the patient if he has had recent sexual contacts or a new sexual partner.
Inspect the patient’s urethral meatus for inflammation and swelling. Using proper technique, obtain a culture specimen. (See Collecting a urethral discharge specimen.) Then obtain a urine sample for urinalysis, culture, and possibly a three-glass urine sample. (See Performing the three-glass urine test, page 608.) In the male patient, the prostate gland may have to be palpated.

Urinary incontinence:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
Ask the patient when he first noticed the incontinence and whether it began suddenly or gradually. Have him describe his typical urinary pattern: Does incontinence usually occur during the day or at night? Does he have any urinary control, or is he totally incontinent? If he is occasionally able to control urination, ask him the usual times and amounts voided. Determine his normal fluid intake. Ask about other urinary problems, such as hesitancy, frequency, urgency, nocturia, and decreased force or interruption of the urine stream. Also ask if he’s ever sought treatment for incontinence or found a way to deal with it himself.
Obtain a medical history, especially noting urinary tract infection, prostate conditions, spinal injury or tumor, stroke, or surgery involving the bladder, prostate, or pelvic floor. Ask a woman how many pregnancies she has had and how many childbirths.
After completing the history, have the patient empty his bladder. Inspect the urethral meatus for obvious inflammation or anatomic defect. Have female patients bear down; note any urine leakage. Gently palpate the abdomen for bladder distention, which signals urine retention. Perform a complete neurologic assessment, noting motor and sensory function and obvious muscle atrophy.

Urinary frequency:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
Ask the patient how many times a day he voids. How does this compare to his previous pattern of voiding? Ask about the onset and duration of the abnormal frequency and about any associated urinary signs or symptoms, such as dysuria, urgency, incontinence, hematuria, discharge, or lower abdominal pain with urination.
Ask also about neurologic symptoms, such as muscle weakness, numbness, or tingling. Explore his medical history for urinary tract infection, other urologic problems or recent urologic procedures, and neurologic disorders. With a male patient, ask about a history of prostatic enlargement. If the patient is a female of childbearing age, ask whether she is or could be pregnant.
Obtain a clean-catch midstream sample for urinalysis and culture and sensitivity tests. Then palpate the patient’s suprapubic area, abdomen, and flanks, noting any tenderness. Examine his urethral meatus for redness, discharge, or swelling. In a male patient, the physician may palpate the prostate gland.
If the patient’s medical history reveals symptoms or a history of neurologic disorders, perform a neurologic examination.

Urinary hesitancy:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
Ask the patient when he first noticed hesitancy and if he’s ever had the problem before. Ask about other urinary problems, especially reduced force or interruption of the urine stream. Ask if he’s ever been treated for a prostate problem or urinary tract infection or obstruction. Obtain a drug history.
Inspect the patient’s urethral meatus for inflammation, discharge, and other abnormalities. Examine the anal sphincter and test sensation in the perineum. Obtain a clean-catch sample for urinalysis and culture. In a male patient, the prostate gland requires palpation. A female patient requires a gynecologic examination.

Urinary urgency:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
Ask the patient about the onset of urinary urgency and whether he’s ever experienced it before. Ask about other urologic symptoms, such as dysuria and cloudy urine. Also ask about neurologic symptoms, such as paresthesia. Examine his medical history for recurrent or chronic UTIs or for surgery or procedures involving the urinary tract.
Obtain a clean-catch sample for urinalysis and culture. Note urine character, color, and odor, and use a reagent strip to test for pH, glucose, and blood. Then palpate the suprapubic area and both flanks for distention and tenderness. If the patient’s history or symptoms suggest neurologic dysfunction, perform a neurologic examination.

Dysuria:
History and physical examination
(Professional Guide to Signs & Symptoms (Fifth Edition))
If the patient complains of dysuria, have him describe its severity and location. When did he first notice it? Did anything precipitate it? Does anything aggravate or alleviate it?
Next, ask about previous urinary or genital tract infections. Has the patient recently undergone an invasive procedure, such as cystoscopy or urethral dilatation, or had a urinary catheter inserted? Also, ask if he has a history of intestinal disease. Ask the female patient about menstrual disorders and use of products that irritate the urinary tract, such as bubble bath salts, feminine deodorants, contraceptive gels, or perineal lotions. Also ask her about vaginal discharge or pruritus.
During the physical examination, inspect the urethral meatus for discharge, irritation, or other abnormalities. A pelvic or rectal examination may be necessary.

Dysuria:
Physical examination
(The 10-Minute Diagnosis Manual: Symptoms and Signs in the Time-Limited Encounter)
The physical examination is essential in narrowing the diagnosis. It helps to rule out pyelonephritis and other systemic infections in patients with dysuria, allowing the physician to search for the less severe causes. Fever, flank tenderness, and suprapubic tenderness are useful findings. A careful genital examination (speculum in women, foreskin retraction and prostate examination in uncircumcised men) can point to specific localized causes. The genital examination also allows collection of samples for testing. Attention to localized lesions (e.g., HSV lesions), discharge (yeast, bacterial vaginosis, gonorrhea, and trichomoniasis) and trauma also help make the diagnosis.
Testing
The history and physical examination usually suggests which tests are most appropriate. A urinalysis is the most common study performed. It is important also to gather samples for gonorrhea, chlamydia, and HSV, using wet preparations and potassium hydroxide testing when appropriate. Rapid tests on urine samples for the detection of bacteria and leukocytes can be done while patients wait. Direct microscopic examination of the urine can isolate bacteria and leukocytes. Rapid dipstick biochemical tests can isolate leukoesterase and nitrate, which are consistent with leukocytes and urea-fixing bacteria. Urine cultures require overnight to 48 hours of incubation to detect specific bacterial pathogens. Pyuria (defined as white blood cell count >10/mm3 of urine) is seen in more than 95% of patients with acute UTI but is uncommon in the absence of infection. Pyuria without bacteriuria suggests a chlamydia infection. Urine dipstick testing is generally less sensitive for pyuria than microscopic examination, but it is more convenient (5).
Diagnostic assessment
Given the many causes of dysuria, an accurate diagnosis can be difficult without a thorough approach to each patient. Because most causes have other associated symptoms and findings, a diagnosis can usually be made with a carefully taken history, a focused physical examination, and appropriate laboratory tests. Separating an uncomplicated UTI or STD from the more serious pyelonephritis and other possible diagnoses is the challenge in these patients.

Nocturia:
Physical examination
(The 10-Minute Diagnosis Manual: Symptoms and Signs in the Time-Limited Encounter)
The extent of the physical examination will be guided by the history. Essential for all patients is a genitourinary examination to identify lower urinary tract abnormalities such as bladder distention, cystocele, or rectocele. Examination of the heart, lungs, and extremities will identify pulmonary, cardiac disease, and peripheral edema. A rectal examination (with sphincter contraction during the examination) will identify sphincter laxity, fecal impaction, tumors, and prostate abnormalities. Absence of the anal wink (S4-5) or bulbocavernosus reflex (S2-3) can indicate spinal cord pathology. (In older patients, the absence of these reflexes is not always pathologic.) An expanded neurologic examination will be necessary in patients with other neurologic symptoms.
Testing
A routine urinalysis by dipstick testing will identify infection and some types of renal disease. A low specific gravity can indicate increased fluid intake or renal disease with the inability to concentrate urine. Microscopic evaluation and urine culture can be helpful in selected cases. Serum blood urea nitrogen and creatinine can be elevated in renal disease. Urine electrolytes can help to diagnose diabetes insipidus. Measurement of postvoid residual urine will evaluate for urinary retention. A voiding diary with measurement of urine volume can be helpful. If the nighttime voided urine volume is high, the cause is excessive urine production. If the volume is less than bladder capacity (highest daytime voided volume), the nocturia is caused by a sleep-related problem or lower urinary tract pathology. Cystoscopy, renal ultrasound, intravenous pyelogram, and urodynamic studies are not usually needed in the evaluation of nocturia.
Diagnostic assessment
Patients with excessive fluid intake or use of alcohol or caffeine near bedtime or patients on medications (e.g., diuretics, theophylline, or calcium channel blockers) may complain of nocturia. Aging is associated with a loss of the nocturnal increase in vasopressin and increased nocturnal urine production (2). Nocturia, frequency, urgency, and dysuria coupled with a positive urinalysis indicate a urinary tract infection. Findings of rales on lung examination, an S3 gallop, and lower extremity edema suggests congestive heart failure. COPD can cause respiratory acidosis and increased excretion of hydrogen ion with the production of an acid urine and bladder irritation (4). In a male patient, a diminished urinary stream and an enlarged prostate suggest prostatic hypertrophy and obstructive uropathy. Patients with insomnia from any number of causes (depression, pain, dyspnea, and so on) may experience nocturia. Be alert for the patient with nocturia secondary to neurologic conditions, which can cause inadequate secretion of vasopressin (diabetes insipidus).

Urethral Discharge:
Physical examination
(The 10-Minute Diagnosis Manual: Symptoms and Signs in the Time-Limited Encounter)
A. Focused physical examination (PE) should include vital signs, and urologic and rectal examination. In men, this should include examination of the penis, perimeatal region (for evidence of erythema), urethral meatus, scrotum, testicles, epididymis, prostate, and perianal and inguinal region. Stains present on the patient’s underwear may indicate the characteristics of the discharge, which is particularly useful in a patient who has urinated shortly before examination. Recent micturition can eliminate much inflammatory discharge. Sometimes it is necessary to examine the patient in the morning before voiding to enhance the diagnosis. Perform a complete gynecologic and urologic examination in women.
B. Abdomen. Completely examine the abdomen to rule out intraabdominal pathology, including masses and inflammation, obstruction, or distention of organs.
C. Additional physical examination should include the skin and other systems, as needed. If a patient is suspected of gonococcal infection, it may be essential to check the patient’s joints, skin, throat, eye and other organs.
Testing
A. UD sample collection. Proper collection and handling of UD sample is essential for the diagnosis. When the discharge is not spontaneous, the urethra should be gently stripped. This is best accomplished by grasping the penis firmly between the thumb and forefinger with the thumb pressing on the ventral surface. Then move the hand distally, compressing the urethra. This maneuver may express a small amount of discharge. The urethral meatus can be gently spread and if no urethral discharge is expressed, a calcium-alginate urethral (or nasopharyngeal) swab should be inserted at least 2 cm into the urethra and the discharge collected. The use of cotton-tipped swabs is contraindicated because their large size makes the insertion extremely uncomfortable and the cotton fibers can inhibit the growth of certain fastidious organisms (4).
B. Clinical laboratory investigations
1. UD Gram’s stain. The test involves staining the UD with Gram’s stain and examining it under a microscope. The presence of polymorphs with intracellular diplococci is diagnostic of GC. Polymorphs without the intracellular diplococci are suggestive of NGC disease. Few or no polymorphs are suggestive of other causes. The Gram’s stain is quite accurate for men but it is not very sensitive for women (50%).
2. UD culture is essential to identify specific organisms. Other useful tests are:
a. Detection of bacterial DNA by polymerase chain reaction (PCR)
b. DNA probes
c. Direct monoclonal testing and enzyme-linked assays. These tests have a high sensitivity and specificity. Cultures of throat, rectum, and sometimes conjunctivae may be required to establish the diagnosis.
3. UD wet preparation is done to establish the diagnosis of trichomoniasis, candidiasis, and some viral and bacterial infections.
4. Urine analysis and urine cultures are essential for the diagnosis of urinary infections. Collect the urine specimen [as described by Stamey (5)] with four sterile containers (before and after prostatic massage), which is useful to identify the site of infection in men.
5. Urinary leukocyte esterase is a useful screening test for chlamydial and GC infections in asymptomatic men. The usefulness of other neutrophil enzyme (elastace, myeloperoxidase) studies of urine have been reported.
6. Blood studies, including a complete blood count, serum chemistry profile, serologic test for syphilis, blood test for human immunodeficiency virus infection, and immunologic studies, may be required in an appropriate clinical setting.
C. Diagnostic imaging. Urethrogram, urologic diagnostic studies, and pelvic, vaginal, and rectal ultrasound studies are indicated in some clinical conditions.
D. Diagnostic procedures. Children and elderly patients may need to be examined under anesthesia to evaluate UD. Anoscopy is done for patients who have had anal intercourse or for those with anal and rectal symptoms. Cystourethroscopy and laparoscopy are also useful in certain conditions.
Diagnostic assessment
A. Special concerns. Neisseria gonorrhoeae and C. trachomatis infections are reportable to State Health Departments and a specific diagnosis is essential. UD secondary to STD involves many psychosocial and medicolegal implications to the patient, his or her partner, their families, and society. Sexual partners can be traced, tested, and treated. In children with UD, sexual abuse may be suspected. Pregnant women with gonococcal infection or chlamydia can infect the infant at birth (ophthalmia neonatorum).
B. Complications following UD and urethritis. Some of the complications following UD are postgonococcal urethritis, pelvic inflammatory disease (in women) and infertility, perihepatitis, chronic pelvic pain (Chapter 11.3), adhesions of the intraabdominal organs, obstructions in the gastrointestinal and genitourinary tracts, chronic urethritis, periurethral abscess, fistula, prostatitis, epididymitis, orchitis, urethral syndrome, psychosexual problems, and Reiter’s syndrome.

Urinary Incontinence:
Physical examination
(The 10-Minute Diagnosis Manual: Symptoms and Signs in the Time-Limited Encounter)
The physical examination is often normal in cases of UI. Focus efforts in an attempt to uncover the underlying cause(s):
A. General. Is the patient physically capable of getting to the toilet?
B. Mental status. Can the patient understand and act on the urge to void?
C. Neurologic, including the anal reflex; focal signs suggest a neurologic cause.
D. Abdominal examination. Is the bladder distended?
E. Rectal or prostate. Does the patient have a fecal impaction or an enlarged prostate?
F. Pelvic examination. Look for atrophic vaginitis, uterine prolapse, or a pelvic mass.
Testing
A. Voiding journal. A voiding journal is a good way to get additional information about the patient’s problem. Have the patient record the time and approximate amount of each voiding, and whether they were wet or dry.
B. Urinalysis. Be cautious when interpreting the urine analysis: in the absence of other symptoms, bacteriuria is seldom the primary cause of UI. Treat cystitis or urethritis when the rest of the clinical picture confirms them. Unexplained, persistent microhematuria requires investigation (Chapter 10.2).
C. Postvoiding urine volume. The patient should be catheterized immediately after voiding. In general, the postvoid urine volume should be less than 50 ml. Volumes in the range of 100 to 200 ml may suggest impaired bladder contractility or obstruction. Volumes greater than 200 ml strongly suggest obstruction.
D. Blood urea nitrogen, creatinine, and glucose are simple blood tests that help rule out underlying renal disease and diabetes.
E. Special tests are available via urologic consultation to further delineate the cause of UI. These include cystoscopy, cystometry, and other voiding studies. Up to two-thirds of patients can be successfully treated without urologic referral.
Diagnostic assessment
The clinical history is the most important factor leading to the correct diagnosis and successful treatment of urinary incontinence. However, it is an imperfect tool at best. In one review, clinical history had a sensitivity and specificity for stress incontinence of 0.90 and 0.50, respectively. For detrusor instability, the figures were 0.74 and 0.55 (2).
The task becomes even more problematic when considering the reluctance of patients to talk about their symptoms and the tendency for UI to be of a mixed type. Response to therapy (or lack thereof) often drives the practical management of this condition. Lack of response to multiple trials of therapy is a good indication for consulting a urologist. Remember, that your initial assessment will often be incorrect, so keep an open mind and consider all possible diagnoses. Finally, recall that UI frequently involves more than one causal factor. For example, many elderly people have a functional component (can’t get to the toilet quickly) in addition to one of the other types.

Dysuria:
Diagnostic Approach
(Field Guide to Bedside Diagnosis)
In women, ask whether burning is internal (urinary tract infection) or external (vaginitis). Women who have had a prior urinary tract infection are more than 90% accurate in identifying recurrences.
The urine dipstick is a useful diagnostic adjunct for determining the presence of pyuria. Leukocyte esterase and nitrate tests are complementary, increasing the overall sensitivity.
Always consider a sexually transmitted infection, especially with minimal pyuria and/or a new sexual partner.
The combination of symptoms of dysuria and frequency without vaginal discharge or irritation has an overall likelihood ratio of 24.6 in predicting acute urinary tract infection.

Polyuria:
Diagnostic Approach
(Field Guide to Bedside Diagnosis)
Polyuria is output of 3 L or more daily, and should be differentiated from urinary frequency and nocturia. Nocturia is most commonly due to drinking fluids before sleep, but is also associated with congestive heart failure, cirrhosis, nephrotic syndrome, chronic renal failure and diuretics. Mechanisms of polyuria include: loss of renal concentrating ability (parenchymal disease); decreased bladder capacity; solute diuresis of glucose (diabetes), urea (hypercatabolic states), mannitol, or radiocontrast; postobstructive and post-ATN nephropathy; and decreased responsiveness of the tubule to aldosterone with sodium diuresis (cystic renal disease, Bartter syndrome, or resolving ATN).

Proteinuria:
Diagnostic Approach
(Field Guide to Bedside Diagnosis)
Proteinuria may present on urinalysis or as edema caused by reduced oncotic pressure from serum albumin loss. The dipstick detects albumin in concentrations of 30 mg/dL (Sensitivity 70%, Specificity 92%, Likelihood ratio 8.8), or 300 to 500 mg of proteinuria per day. False positives may be seen with dehydration and hematuria, both of which can be detected with the dipstick (specific gravity and hemoglobin). False negatives can occur when the protein is a low molecular weight tubular protein (not albumin), e.g., immunoglobulin light chains in myeloma or beta-2 microglobulin. In nephrotic syndrome more than 3.5 grams per day of proteinuria occurs.
Systemic disease should be suspected in the presence of fever, rash, or arthritis.

Urinary Incontinence:
Diagnostic Approach
(Field Guide to Bedside Diagnosis)
On examination, test for stress-induced leakage with a full bladder, palpate for bladder distension after voiding, and check for post-void residual. Do a pelvic examination looking for pelvic floor laxity, atrophic vaginitis, urethritis, or pelvic mass, and a rectal examination for tone, fecal impaction, and prostate nodule. Check perineal sensation and neurosacral reflexes including volitional anal contraction, anal wink (anal contraction in response to a light scratch of the perineal skin), and bulbocavernosus reflex (anal contraction in response to a light squeeze of the penis or clitoris). An intact reflex arc but absent perineal sensation suggests a cord lesion or multiple sclerosis.
Urge incontinence: Due to detrusor overactivity. Urine loss is accompanied by a strong desire to void. Incontinence is preceded by a warning of seconds to minutes. Leakage is periodic but frequent, and nocturnal incontinence is common. Voluntary control of the anal sphincter is intact, and sacral sensation and reflexes are preserved. The post-void residual is low. It is usually a result of detrusor instability caused by stroke, Alzheimer dementia, brain tumor, Parkinson disease, bladder outlet obstruction, spinal cord lesion, or interstitial cystitis.
Reflex incontinence: Due to an excessive pressure response to bladder filling. Voiding occurs without stress or warning. Sacral reflexes are preserved, but voluntary sphincter control and perineal sensation are impaired. Post-void residual is increased. Usually caused by a spinal cord lesion, incontinence may be mimicked by cortical damage with decreased awareness of signals to void.
Stress incontinence: Due to failure of the sphincter to remain closed during bladder filling. Incontinence of small amounts of urine occurs with increased abdominal pressure (e.g., coughing, laughing, sneezing). Stress-induced detrusor instability is suggested by a 5 to 15 second delay between stress and leakage, and by nocturnal leakage.
Overflow incontinence: Due to impaired detrusor contractility and/or bladder outlet obstruction. There is frequent leakage of small amounts of urine, hesitancy, decreased flow, and incomplete emptying. The post-void residual is increased, and the bladder is palpable. Common mechanisms include bladder outlet obstruction caused by benign prostatic hypertrophy or urethral stricture; decreased detrusor tone due to a herniated disc; or peripheral neuropathy caused by diabetes, pernicious anemia, tabes, or cauda equina.

Bladder distention:
Physical assessment
(Signs & Symptoms: A 2-in-1 Reference for Nurses)
Take the patient’s vital signs, and percuss and palpate the bladder. (Remember that if the bladder is empty, it can’t be palpated through the abdominal wall.) Inspect the urethral meatus, and measure its diameter. Describe the appearance and amount of any discharge. Finally, test for perineal sensation and anal sphincter tone; in male patients, digitally examine the prostate gland.

Dysuria:
Physical assessment
(Signs & Symptoms: A 2-in-1 Reference for Nurses)
Ask the patient to void before beginning your examination. Inspect the urethral meatus for discharge, irritation, and other abnormalities. Then percuss over the kidneys. Costovertebral angle tenderness indicates kidney inflammation. Percuss the bladder. Start at the symphysis pubis and percuss upward. You should hear tympany; a dull sound signals retained urine. Then palpate the kidneys. Normally, they aren’t palpable unless they’re enlarged. If the kidneys feel enlarged, the patient may have hydronephrosis, cysts, or tumors. You won’t be able to palpate the bladder unless it’s distended. (See Palpating the kidneys.) A pelvic or rectal examination may be necessary.

Dysuria:
Diagnostic Approach
(The Diagnostic Approach to Symptoms and Signs in Pediatrics)
History and physical exam are usually diagnosticof trauma, vulvovaginitis, labial adhesions, chemical irritation,and diaper dermatitis. Otherwise, suspect UTI and perform UA andurine culture.
Urinalysis
Presenceof WBCs (>10/high-power field) in sediment ofcentrifuged specimen of urine suggests but is not diagnostic ofUTI. Neither is positive leukocyte esterase test (urine dipstick), whichindicates presence of WBCs in urine.Positive nitrite test using nitritestrip (Griess test) on urine dipstick is highly sensitive and specificfor detection of gram-negative bacteria (e.g., E. coli, Klebsiella,and Proteus species). Positive reaction usually indicates 105 CFUs/mL.False-positive reactions are uncommon if urine is fresh; however,if urine is not examined immediately, test result may be positivebecause of bacteria growing at room temperature. False-negativereactions may occur when there has been inadequate time for bacterialproliferation (random collection rather than first morning specimen)or when infection is due to Enterococcal species and some Staphylococcaland Pseudomonas species that do not convert nitrate to nitrite.Presence of ≥1 bacteria/oilimmersion field of unspun urine (unstained or Gram stain) from clean-catchmidstream specimen correlates with urine colony count of >105 CFUs/mL80–95% of the time. Urine Culture
Quantitative culture of properly collectedurine specimen establishes diagnosis of UTI, and susceptibilitytesting can be performed. Table15.1, based on data from many studies, is useful guidefor diagnosis of UTI.

Proteinuria:
Diagnostic Approach
(The Diagnostic Approach to Symptoms and Signs in Pediatrics)
First stepin evaluation of a child with proteinuria is to determine if thereare any predisposing factors for transient or functional proteinuria(e.g., fever or strenuous exercise).If history is negative for these factorsand dipstick protein is persistently ≥1+, next step isto do complete UA and determine protein:creatinine ratio in a firstmorning spot urine specimen.If results of UA are normal and protein:creatinineratio is in normal range, diagnosis is postural proteinuria andno further studies are necessary.If results of UA are otherwise abnormalor first morning protein:creatinine ratio is above normal, furtherstudies are necessary. Serum electrolytes, creatinine, albumin,and cholesterol as well as blood urea nitrogen should be measured,and renal U/S should be performed. C3 and antinuclear antibody shouldbe considered.If diagnosis remains uncertain andno chemical or radiographic evidence of renal disease exists, renalbiopsy may be performed or child may tentatively be considered tohave benign persistent proteinuria. If renal biopsy is not performedor is normal, child should be monitored at 6-mo intervals for urinaryand chemical changes indicative of renal disease.

Polyuria and Polydipsia:
Diagnostic Approach
(The Diagnostic Approach to Symptoms and Signs in Pediatrics)
Polyuriamust be distinguished from small volume urinary frequency, whichis common in pediatric practice. Children with polyuria often havenocturia and are unable to sleep through the night without wakingup to urinate. Most children with urinary frequency do not havepolyuria or a defect in urinary concentrating ability. Common causesof isolated urinary frequency are habit, attention-seeking behavior,and urinary tract infection.Random sample of urine with specificgravity of >1.028 and absence of polyuria rules out a concentrationdefect. Even urinary specific gravity of >1.020 on randomor early morning sample indicates sufficient urinary concentrationsuch that symptomatic diabetes insipidus is unlikely. Children whohave urine with a somewhat lower than normal specific gravity butwho can sleep through the night without passing urine do not needfurther evaluation.Presence of polyuria, dehydration,and high urinary specific gravity is evidence for osmotic diuresis,which is most commonly caused by diabetes mellitus. Dilute urineassociated with polyuria suggests diabetes insipidus or psychogenicpolydipsia. If blood glucose and urea nitrogen are normal, high serumosmolality with hyposmolar urine suggests ADH deficiency or resistance.Low serum osmolality with hyposmolar urine suggests primary polydipsia.With either ADH deficiency or resistance,urine specific gravity rarely exceeds 1.005 and urinary osmolalityrarely exceeds 200 mOsm/kg. Water deprivation test thatdemonstrates inability to concentrate urine indicates diabetes insipidusand distinguishes it from primary polydipsia. If urine remains hypotonicwith dehydration, next step is to determine response to exogenousvasopressin, which distinguishes ADH deficiency from resistance.With ADH deficiency, administration of vasopressin causes diminishingof symptoms and increase in urine specific gravity, whereas no responseoccurs with ADH resistance.With suspected renal disease, certaintests should be performed: CBC and differential; UA; urine culture;serum electrolytes, calcium, phosphorus, and creatinine; blood ureanitrogen; hemoglobin electrophoresis; and renal U/S. Othertests (e.g., determination of serum and urinary amino acids, voiding cystourethrography,and renal biopsy) may be necessary to define specific renal abnormality.Psychosocial history of emotional disturbance,including episodes of compulsive water drinking and formation ofconcentrated urine with fluid deprivation, are evidence for psychogenicpolydipsia. This disorder may sometimes be difficult to distinguishfrom hypothalamic thirst defect, and consultation with a pediatricendocrinologist is recommended.

Bladder distention:
History and physical examination
(Nursing: Interpreting Signs and Symptoms)
If distention isn't severe, begin by reviewing the patient's voiding patterns. Find out the time and amount of the patient's last voiding and the amount of fluid consumed since then. Ask if he has difficulty urinating. Does he use Valsalva's maneuver or Credé's method to initiate urination? Does he urinate with urgency or without warning? Is urination painful or irritating? Ask about the force and continuity of his urine stream and whether he feels that his bladder is empty after voiding.
Explore the patient's history of urinary tract obstruction or infections; venereal disease; neurologic, intestinal, or pelvic surgery; lower abdominal or urinary tract trauma; and systemic or neurologic disorders. Note his drug history, including his use of over-the-counter drugs and herbal medicines.
Take the patient's vital signs, and percuss and palpate the bladder. (Remember that if the bladder is empty, it can't be palpated through the abdominal wall.) Inspect the urethral meatus, and measure its diameter. Describe the appearance and amount of any discharge. Finally, test for perineal sensation and anal sphincter tone; in male patients, digitally examine the prostate gland.

Dysuria:
History and physical examination
(Nursing: Interpreting Signs and Symptoms)
If the patient complains of dysuria, have him describe its severity and location. When did he first notice it? Did anything precipitate it? Does anything aggravate or alleviate it?
Next, ask about previous urinary or genital tract infections. Has the patient recently undergone an invasive procedure, such as cystoscopy or urethral dilatation, or had a urinary catheter placed? Also ask if he has a history of intestinal disease. Ask the female patient about menstrual disorders and the use of products that irritate the urinary tract, such as bubble bath salts, feminine deodorants, contraceptive gels, or perineal lotions. Also ask her about vaginal discharge or pruritus.
During the physical examination, inspect the urethral meatus for discharge, irritation, or other abnormalities. A pelvic or rectal examination may be necessary.

Nocturia:
History and physical examination
(Nursing: Interpreting Signs and Symptoms)
Begin by exploring the history of the patient's nocturia. When did it begin? How often does it occur? Can the patient identify a specific pattern or precipitating factors? Also, note the volume of urine voided. Ask the patient about changes in the color, odor, or consistency of his urine. Has the patient changed his usual pattern or volume of fluid intake? Next, explore associated symptoms. Ask about pain or burning on urination, difficulty initiating a urine stream, costovertebral angle (CVA) tenderness, and flank, upper abdominal, or suprapubic pain.
Determine if the patient or his family has a history of renal or urinary tract disorders or endocrine and metabolic diseases, particularly diabetes. is the patient taking a drug that increases urine output, such as a diuretic, a cardiac glycoside, or an antihypertensive?
Focus your physical examination on palpating and percussing the kidneys, CVA, and bladder. Carefully inspect the urinary meatus. Inspect a urine specimen for color, odor, and the presence of sediment.

Polyuria:
History and physical examination
(Nursing: Interpreting Signs and Symptoms)
Because the patient with polyuria is at risk for developing hypovolemia, evaluate his fluid status first. Take his vital signs, noting an increased body temperature, tachycardia, and orthostatic hypotension (a 10 mm Hg decrease in systolic blood pressure upon standing and a 10 beats/minute increase in heart rate upon standing). Inspect for dry skin and mucous membranes, decreased skin turgor and elasticity, and reduced perspiration. Is the patient unusually tired or thirsty? Has he recently lost more than 5% of his body weight? If you detect these effects of hypovolemia, you'll need to infuse replacement fluids.
If the patient doesn't display signs of hypovolemia, explore the frequency and pattern of the polyuria. When did it begin? How long has it lasted? Was it precipitated by a certain event? Ask the patient to describe the pattern and amount of his daily fluid intake. Check for a history of visual deficits, headaches, or head trauma, which may precede diabetes insipidus. Also check for a history of urinary tract obstruction, diabetes mellitus, renal disorders, chronic hypokalemia or hypercalcemia, or psychiatric disorders (past and present). Find out the schedule and dosage of any drugs the patient is taking.
Perform a neurologic examination, noting especially any change in the patient's level of consciousness. Then palpate the bladder and inspect the urethral meatus. Obtain a urine specimen and check its specific gravity.

Urethral discharge:
History and physical examination
(Nursing: Interpreting Signs and Symptoms)
Ask the patient when he first noticed the discharge, and have him describe its color, consistency, and quantity. Does he experience pain or burning on urination? Does he have difficulty initiating a urine stream? Does he experience urinary frequency? Ask the patient about other associated signs and symptoms, such as fever, chills, and perineal fullness. Explore his history for prostate problems, sexually transmitted disease, or urinary tract infection. Ask the patient if he has had recent sexual contacts or a new sexual partner. Obtain a complete drug history.
Inspect the patient's urethral meatus for inflammation and swelling. Using proper technique, obtain a culture specimen. (See Collecting a urethral discharge specimen.) Then obtain a urine specimen for urinalysis, culture, and possibly a three-glass urine specimen. (See Performing the three-glass urine test, page 613.) In the male patient, the prostate gland may have to be palpated.

Urinary incontinence:
History and physical examination
(Nursing: Interpreting Signs and Symptoms)
Ask the patient when he first noticed the incontinence and whether it began suddenly or gradually. Have him describe his typical urinary pattern: Does incontinence usually occur during the day or at night? Does he have any urinary control, or is he totally incontinent? If he can occasionally control urination, ask him the usual times and amounts voided. Determine his normal fluid intake. Ask about other urinary problems, such as hesitancy, frequency, urgency, nocturia, and decreased force or interruption of the urine stream. Also ask if he has ever sought treatment for incontinence or found a way to deal with it himself.
Obtain a medical history, especially noting urinary tract infection (UTI), prostate conditions, spinal injury or tumor, stroke, or surgery involving the bladder, prostate, or pelvic floor. Ask a woman how many pregnancies she has had and how many childbirths. A diary of voiding habits for a 24- to 48-hour period may provide useful information. Obtain a complete drug history.
After completing the history, have the patient empty his bladder. Inspect the urethral meatus for obvious inflammation or anatomic defect. Have female patients bear down; note any urine leakage. Gently palpate the abdomen for bladder distention, which signals urine retention. Perform a complete neurologic assessment, noting motor and sensory function and obvious muscle atrophy.

Urinary frequency:
History and physical examination
(Nursing: Interpreting Signs and Symptoms)
Ask the patient how many times per day he voids. How does this compare with his previous pattern of voiding? Ask about the onset and duration of the abnormal frequency and about any associated urinary signs or symptoms, such as dysuria, urgency, incontinence, hematuria, discharge, or lower abdominal pain with urination.
Ask also about neurologic symptoms, such as muscle weakness, numbness, or tingling. Explore his medical history for urinary tract infection, other urologic problems or recent urologic procedures, and neurologic disorders. With a male patient, ask about a history of prostatic enlargement. If the patient is a female of childbearing age, ask whether she is or could be pregnant. Obtain a complete drug history.
Obtain a clean-catch midstream specimen for urinalysis and culture and sensitivity tests. Then palpate the patient's suprapubic area, abdomen, and flanks, noting any tenderness. Examine his urethral meatus for redness, discharge, or swelling. In a male patient, the physician may palpate the prostate gland.
If the patient's medical history reveals symptoms or a history of neurologic disorders, perform a neurologic examination.

Urinary hesitancy:
History and physical examination
(Nursing: Interpreting Signs and Symptoms)
Ask the patient when he first noticed hesitancy and if he has ever had the problem before. Ask about other urinary problems, especially reduced force or interruption of the urine stream. Ask if he has ever been treated for a prostate problem or UTI or obstruction. Obtain a drug history.
Inspect the patient's urethral meatus for inflammation, discharge, and other abnormalities. Examine the anal sphincter and test sensation in the perineum. Obtain a clean-catch specimen for urinalysis and culture. In a male patient, the prostate gland requires palpation. A female patient requires a gynecologic examination.

Urinary urgency:
History and physical examination
(Nursing: Interpreting Signs and Symptoms)
Ask the patient about the onset of urinary urgency and whether he has ever experienced it before. Ask about other urologic symptoms, such as dysuria and cloudy urine. Also ask about neurologic symptoms, such as paresthesia. Examine his medical history for recurrent or chronic UTIs or for surgery or procedures involving the urinary tract. Obtain a complete drug history.
Obtain a clean-catch specimen for urinalysis and culture. Note urine character, color, and odor, and use a reagent strip to test for pH, glucose, and blood. Then palpate the suprapubic area and both flanks for distention and tenderness. If the patient's history or symptoms suggest neurologic dysfunction, perform a neurologic examination.
