Neurogenic bladder:
Causes
(Professional Guide to Diseases (Eighth Edition))
At one time, neurogenic bladder was thought to result primarily from spinal cord injury; now, it appears to stem from a host of underlying conditions:
❑ cerebral disorders, such as stroke, brain tumor (meningioma and glioma), Parkinson’s disease, multiple sclerosis, dementia, and incontinence caused by aging
❑ spinal cord disease or trauma, such as herniated vertebral disks, spina bifida, myelomeningocele, spinal stenosis (causing cord compression) or arachnoiditis (causing adhesions between the membranes covering the cord), cervical spondylosis, myelopathies from hereditary or nutritional deficiencies and, rarely, tabes dorsalis
❑ disorders of peripheral innervation, including autonomic neuropathies resulting from endocrine disturbances such as diabetes mellitus (most common)
❑ metabolic disturbances, such as hypothyroidism, porphyria, or uremia (infrequent)
❑ acute infectious diseases such as transverse myelitis
❑ heavy metal toxicity
❑ chronic alcoholism
❑ collagen diseases such as systemic lupus erythematosus
❑ vascular diseases such as atherosclerosis
❑ distant effects of cancer such as primary oat cell carcinoma of the lung
❑ herpes zoster
❑ sacral agenesis.
An upper motor neuron lesion (above S2 to S4) causes spastic neurogenic bladder, with spontaneous contractions of detrusor muscles, elevated intravesical voiding pressure, bladder wall hypertrophy with trabeculation, and urinary sphincter spasms. A lower motor neuron lesion (below S2 to S4) causes flaccid neurogenic bladder, with decreased intravesical pressure, increased bladder capacity and large residual urine retention, and poor detrusor contraction.

Bladder distention:
Medical causes
(Professional Guide to Signs & Symptoms (Fifth Edition))
Benign prostatic hyperplasia (BPH)
In BPH, bladder distention develops gradually as the prostate enlarges. Occasionally, its onset is acute. Initially, the patient experiences urinary hesitancy, straining, and frequency; reduced force of and inability to stop the urine stream; nocturia; and postvoiding dribbling. As the disorder progresses, it produces prostate enlargement, sensations of suprapubic fullness and incomplete bladder emptying, perineal pain, constipation, and hematuria.
Bladder calculi
Bladder calculi may produce bladder distention, but pain is usually the only symptom. The pain is usually referred to the tip of the penis, the vulvar area, the lower back, or the heel. It worsens during walking or exercise and abates when the patient lies down. It’s usually most severe when micturition ceases. The pain may be accompanied by urinary frequency and urgency, terminal hematuria, and dysuria.
Bladder cancer
By blocking the urethral orifice, neoplasms can cause bladder distention. Associated signs and symptoms include hematuria (most common sign); urinary frequency and urgency; nocturia; dysuria; pyuria; pain in the bladder, rectum, pelvis, flank, back, or legs; vomiting; diarrhea; and sleeplessness. A mass may be palpable on bimanual examination.
Cultural Cue: Bladder cancer is twice as common in Whites as in Blacks. It’s relatively uncommon among Asians, Hispanics, and Native Americans.
Multiple sclerosis
In this neuromuscular disorder, urine retention and bladder distention result from interruption of upper motor neuron control of the bladder. Associated signs and symptoms include optic neuritis, paresthesia, impaired position and vibratory senses, diplopia, nystagmus, dizziness, abnormal reflexes, dysarthria, muscle weakness, emotional lability, Lhermitte’s sign (transient, electric-like shocks that spread down the body when the head is flexed), Babinski’s sign, and ataxia.
Prostate cancer
Prostate cancer eventually causes bladder distention in about 25% of patients. Usual signs and symptoms include dysuria, urinary frequency and urgency, nocturia, weight loss, fatigue, perineal pain, constipation, and induration of the prostate or a rigid, irregular prostate on digital rectal examination. In some patients, urine retention and bladder distention are the only signs.
Cultural Cue: Prostate cancer is more common in Blacks than in other ethnic groups.
Prostatitis
In acute prostatitis, bladder distention occurs rapidly along with perineal discomfort and a sensation of suprapubic fullness. Other signs and symptoms include perineal pain; tense, boggy, tender, and warm enlarged prostate; decreased libido; impotence; decreased force of the urine stream; dysuria; hematuria; and urinary frequency and urgency. Additional signs and symptoms include fatigue, malaise, myalgia, fever, chills, nausea, and vomiting.
Bladder distention is rare in chronic prostatitis, which may be accompanied by perineal discomfort, a sensation of suprapubic fullness, prostatic tenderness, decreased libido, urinary frequency and urgency, dysuria, pyuria, hematuria, persistent urethral discharge, ejaculatory pain, and dull pain radiating to the lower back, buttocks, penis, or perineum.
Spinal neoplasms
Disrupting upper neuron control of the bladder, spinal neoplasms cause neurogenic bladder and resultant distention. Associated signs and symptoms include a sense of pelvic fullness, continuous overflow dribbling, back pain that often mimics sciatica pain, constipation, tender vertebral processes, sensory deficits, and muscle weakness, flaccidity, and atrophy. Signs and symptoms of urinary tract infection (dysuria, urinary frequency and urgency, nocturia, tenesmus, hematuria, and weakness) may also occur.
Urethral calculi
In urethral calculi, urethral obstruction leads to interrupted urine flow and bladder distention. The obstruction causes pain radiating to the penis or vulva and referred to the perineum or rectum. It may also produce a palpable stone and urethral discharge.
Urethral stricture
Urethral stricture results in urine retention and bladder distention with chronic urethral discharge (most common sign), urinary frequency (also common), dysuria, urgency, decreased force and diameter of the urine stream, and pyuria. Urinoma and urosepsis may also develop.
Other causes
Catheterization
Using an indwelling urinary catheter can result in urine retention and bladder distention. While the catheter is in place, inadequate drainage due to kinked tubing or an occluded lumen may lead to urine retention. In addition, a misplaced urinary catheter or irritation due to catheter removal may cause edema, thereby blocking urine outflow.
Drugs
Parasympatholytics, anticholinergics, ganglionic blockers, sedatives, anesthetics, and opiates can produce urine retention and bladder distention.

Urethral discharge:
Medical causes
(Professional Guide to Signs & Symptoms (Fifth Edition))
Prostatitis
Acute prostatitis is characterized by a purulent urethral discharge. Initial signs and symptoms include sudden fever, chills, low back pain, perineal fullness, myalgia, and arthralgia. Urination becomes increasingly frequent and urgent, and the urine may appear cloudy. Dysuria, nocturia, and some degree of urinary obstruction may also occur. The prostate may be tense, boggy, tender, and warm. Prostate massage to obtain prostatic fluid is contraindicated.
Chronic prostatitis commonly produces no symptoms, but it may produce a persistent urethral discharge that’s thin, milky or clear, and sometimes sticky. The discharge appears at the meatus after a long interval between voidings—for example, in the morning. Associated effects include a dull ache in the prostate or rectum, sexual dysfunction such as ejaculatory pain, and urinary disturbances, such as frequency, urgency, and dysuria.
Reiter’s syndrome
In this self-limiting syndrome that usually affects males, a urethral discharge and other signs of acute urethritis occur 1 to 2 weeks after sexual contact. Asymmetrical arthritis, conjunctivitis of one or both eyes, and ulcerations on the oral mucosa, glans penis, palms, and soles may also occur.
Urethral neoplasm
This rare cancer is sometimes heralded by a painless urethral discharge that’s initially opaque and gray and later yellowish and blood-tinged. Dysuria progresses to anuria as the urethra becomes blocked.
Urethritis
This inflammatory disorder, which is often sexually transmitted (as in gonorrhea), commonly produces a scant or profuse urethral discharge that’s either thin and clear, mucoid, or thick and purulent. Other effects include urinary hesitancy, urgency, and frequency; dysuria; and itching and burning around the meatus.

Urinary incontinence:
Medical causes
(Professional Guide to Signs & Symptoms (Fifth Edition))
Benign prostatic hyperplasia (BPH)
Overflow incontinence is common in this disorder as a result of urethral obstruction and urine retention. BPH begins with a group of signs and symptoms known as prostatism: reduced caliber and force of the urine stream, urinary hesitancy, and a feeling of incomplete voiding. As the obstruction increases, the patient may develop urinary frequency, nocturia and, possibly, hematuria. Examination reveals bladder distention and an enlarged prostate.
Bladder calculus
Overflow incontinence may occur if the calculus lodges in the bladder neck. Associated findings vary but may include those of an irritable bladder: urinary frequency and urgency, dysuria, hematuria, and suprapubic pain from bladder spasms. Pelvic pain may be referred to the tip of the penis, vulva, low back, or heel and may be exacerbated by movement.
Bladder cancer
Urge incontinence and hematuria are common findings in bladder cancer; obstruction by a tumor may produce overflow incontinence. The early stages can be asymptomatic. Other urinary signs and symptoms include frequency, dysuria, nocturia, dribbling, and suprapubic pain from bladder spasms after voiding. A mass may be palpable on bimanual examination.
Diabetic neuropathy
Autonomic neuropathy may cause painless bladder distention with overflow incontinence. Related findings include episodic constipation or diarrhea (which is commonly nocturnal), impotence and retrograde ejaculation, orthostatic hypotension, syncope, and dysphagia.
Guillain-Barré syndrome
Urinary incontinence may occur early in this disorder as a result of peripheral and autonomic nerve dysfunction. The cardinal sign is progressive, profound muscle weakness, which typically starts in the legs and extends to the arms and facial nerves within 24 to 72 hours. Associated findings include paresthesia, dysarthria, nasal speech, dysphagia, orthostatic hypotension, tachycardia, fecal incontinence, diaphoresis, drooling, and pain in the shoulders, thighs, or lumbar region.
Multiple sclerosis (MS)
Urinary incontinence, urgency, and frequency are common urologic findings in MS. Visual problems and sensory impairment are usually the first symptoms. Other findings include constipation, muscle weakness, paralysis, spasticity, hyperreflexia, intention tremor, ataxic gait, dysarthria, impotence, and emotional lability.
Prostate cancer
Urinary incontinence usually occurs only in the advanced stages of prostate cancer. Urinary frequency and hesitancy, nocturia, dysuria, bladder distention, perineal pain, constipation, and a hard, irregularly shaped, nodular prostate are other common late findings.
Prostatitis (chronic)
Urinary incontinence may occur as a result of urethral obstruction from an enlarged prostate. Other findings include urinary frequency and urgency, dysuria, hematuria, bladder distention, a persistent urethral discharge, dull perineal pain that may radiate to other areas, ejaculatory pain, and decreased libido.
Spinal cord injury
Complete cord transection above the sacral level causes flaccid paralysis of the bladder. Overflow incontinence follows rapid bladder distention. Other findings include paraplegia, sexual dysfunction, sensory loss, muscle atrophy, anhidrosis, and loss of reflexes distal to the injury.
Stroke
Urinary incontinence may be transient or permanent in a stroke patient. Associated findings reflect the site and extent of the lesion and may include impaired mentation, emotional lability, behavioral changes, altered level of consciousness, and seizures. Sensorimotor effects may include contralateral hemiplegia, dysarthria, dysphagia, ataxia, apraxia, agnosia, aphasia, and unilateral sensory loss. Headache, vomiting, visual deficits, and decreased visual acuity may also occur.
Urethral stricture
Partial obstruction of the lower urinary tract due to trauma or infection produces urinary hesitancy, tenesmus, and decreased force and caliber of the urine stream. Urinary frequency and urgency, nocturia, and eventually overflow incontinence may also occur. As the obstruction increases, urine extravasation may lead to formation of urinomas and urosepsis.
UTI
Besides incontinence, a UTI may produce urinary urgency, dysuria, hematuria, cloudy urine and, in males, a urethral discharge. Bladder spasms or a feeling of warmth during urination may occur.
Other causes
Surgery
Urinary incontinence may occur after prostatectomy as a result of urethral sphincter damage.

Bladder cancer:
Causes
(Handbook of Diseases)
Certain environmental carcinogens — such as 2-naphthylamine, benzidine, tobacco, and nitrates — predispose people to transitional cell tumors. Thus, workers in certain industries (rubber workers, weavers, leather finishers, aniline dye workers, hairdressers, petroleum workers, and spray painters) are at high risk for such tumors. The period between exposure to the carcinogen and development of symptoms is about 18 years.
Squamous cell carcinoma of the bladder is most common in geographic areas where schistosomiasis is endemic. It’s also associated with chronic bladder irritation and infection (for example, from kidney stones, indwelling urinary catheters, and cystitis caused by cyclophosphamide).

Urinary tract infection, lower:
Causes
(Handbook of Diseases)
Most lower UTIs result from ascending infection by a single gram-negative enteric bacterium, such as Escherichia coli, Klebsiella, Proteus, Enterobacter, Pseudomonas, or Serratia. However, in a patient with neurogenic bladder, an indwelling urinary catheter, or a fistula between the intestine and bladder, lower UTI may result from simultaneous infection with multiple pathogens.
Infection may result from a breakdown in local defense mechanisms in the bladder that allow bacteria to invade the bladder mucosa and multiply. These bacteria cannot be readily eliminated by normal micturition.
The risk of cystitis is higher when the bladder or urethra becomes blocked and urine flow stops. It can occur when instruments are inserted into the urinary tract during procedures such as catheterization or cystoscopy. Other risks include pregnancy, diabetes, and a history of analgesic or reflux nephropathy. The elderly are at increased risk for developing UTIs due to incomplete emptying of the bladder; this is associated with conditions such as benign prostatic hyperplasia (BPH), prostatitis, and urethral strictures. Also, lack of adequate fluids, bowel incontinence, immobility or decreased mobility, indwelling urinary catheters, and placement in a nursing home all place the person at risk for developing an infection.
Bacterial flare-up
During treatment, bacterial flare-up is generally caused by the pathogenic organism’s resistance to the prescribed antimicrobial therapy. The presence of even a small number (less than 10,000/ml) of bacteria in a midstream urine sample obtained during treatment casts doubt on the treatment’s effectiveness.
Recurrent UTI
In 99% of patients, recurrent lower UTI results from reinfection by the same organism or from some new pathogen; in the remaining 1%, recurrence reflects persistent infection, usually from renal calculi, chronic bacterial prostatitis, or a structural anomaly that may become a source of infection.

(Nursing: Interpreting Signs and Symptoms)
Benign prostatic hyperplasia (BPH).With BPH, bladder distention gradually develops as the prostate enlarges. Occasionally, its onset is acute. Initially, the patient experiences urinary hesitancy, straining, and frequency; reduced force of and the inability to stop the urine stream; nocturia; and postvoiding dribbling. As the disorder progresses, it produces prostate enlargement, sensations of suprapubic fullness and incomplete bladder emptying, perineal pain, constipation, and hematuria.
Bladder calculi.Bladder calculi may produce bladder distention, but more commonly pain is the only symptom. The pain is usually referred to the tip of the penis, the vulvar area, the lower back, or the heel. It worsens during walking or exercise and abates when the patient lies down. It can be accompanied by urinary frequency and urgency, terminal hematuria, and dysuria. Pain is usually most severe when micturition ceases.
Bladder cancer.By blocking the urethral orifice, neoplasms can cause bladder distention. Associated signs and symptoms include hematuria (most common sign); urinary frequency and urgency; nocturia; dysuria; pyuria; pain in the bladder, rectum, pelvis, flank, back, or legs; vomiting; diarrhea; and sleeplessness. A mass may be palpable on bimanual examination.
Multiple sclerosis.With multiple sclerosis, a neuromuscular disorder, urine retention and bladder distention result from the interruption of upper motor neuron control of the bladder. Associated signs and symptoms include optic neuritis, paresthesia, impaired position and vibratory senses, diplopia, nystagmus, dizziness, abnormal reflexes, dysarthria, muscle weakness, emotional lability, Lhermitte's sign (transient, electric-like shocks that spread down the body when the head is flexed), Babinski's sign, and ataxia.
Prostate cancer.Prostate cancer eventually causes bladder distention in about 25% of patients. Usual signs and symptoms include dysuria, urinary frequency and urgency, nocturia, weight loss, fatigue, perineal pain, constipation, and induration of the prostate or a rigid, irregular prostate on digital rectal examination. For some patients, urine retention and bladder distention are the only signs.
Prostatitis.With acute prostatitis, bladder distention occurs rapidly along with perineal discomfort and suprapubic fullness. Other signs and symptoms include perineal pain; a tense, boggy, tender, and warm enlarged prostate; decreased libido; impotence; decreased force of the urine stream; dysuria; hematuria; and urinary frequency and urgency. Additional signs and symptoms include fatigue, malaise, myalgia, fever, chills, nausea, and vomiting.
With chronic prostatitis, bladder distention is rare; however, it may be accompanied by sensations of perineal discomfort and suprapubic fullness, prostatic tenderness, decreased libido, urinary frequency and urgency, dysuria, pyuria, hematuria, persistent urethral discharge, ejaculatory pain, and a dull pain radiating to the lower back, buttocks, penis, or perineum.
Spinal neoplasms.Disrupting upper neuron control of the bladder, spinal neoplasms cause neurogenic bladder and resultant distention. Associated signs and symptoms include a sense of pelvic fullness, continuous overflow dribbling, back pain that typically mimics sciatica pain, constipation, tender vertebral processes, sensory deficits, and muscle weakness, flaccidity, and atrophy. Signs and symptoms of urinary tract infection (dysuria, urinary frequency and urgency, nocturia, tenesmus, hematuria, and weakness) may also occur.
Urethral calculi.With urethral calculi, urethral obstruction leads to bladder distention. The patient experiences interrupted urine flow. The obstruction causes pain radiating to the penis or vulva and referred to the perineum or rectum. It may also produce a palpable stone and urethral discharge.
Urethral stricture.Urethral stricture results in urine retention and bladder distention with chronic urethral discharge (most common sign), urinary frequency (also common), dysuria, urgency, decreased force and diameter of the urine stream, and pyuria. Urinoma and urosepsis may also develop.
Other causes
Catheterization.Using an indwelling urinary catheter can result in urine retention and bladder distention. While the catheter is in place, inadequate drainage due to kinked tubing or an occluded lumen may lead to urine retention. In addition, a misplaced urinary catheter or irritation with catheter removal may cause edema, thereby blocking urine outflow.
Drugs.Parasympatholytics, anticholinergics, ganglionic blockers, sedatives, anesthetics, and opiates can produce urine retention and bladder distention.

Urethral discharge:
Medical causes
(Nursing: Interpreting Signs and Symptoms)
Prostatitis.Acute prostatitis is characterized by purulent urethral discharge. Initial signs and symptoms include sudden fever, chills, lower back pain, myalgia, perineal fullness, and arthralgia. Urination becomes increasingly frequent and urgent, and the urine may appear cloudy. Dysuria, nocturia, and some degree of urinary obstruction may also occur. The prostate may be tense, boggy, tender, and warm. Prostate massage to obtain prostatic fluid is contraindicated.
Chronic prostatitis, although commonly producing no symptoms, may produce a persistent urethral discharge that's thin, milky, or clear and sometimes sticky. The discharge appears at the meatus after a long interval between voidings, as in the morning. Associated effects include a dull aching in the prostate or rectum, sexual dysfunction such as ejaculatory pain, and urinary disturbances such as frequency, urgency, and dysuria.
Reiter's syndrome.In Reiter's syndrome (also known as reactive arthritis), urethral discharge and other signs of acute urethritis occur 1 to 2 weeks after sexual contact. Asymmetrical arthritis, conjunctivitis of one or both eyes, and ulcerations on the oral mucosa, glans penis, palms, and soles may also occur with Reiter's syndrome.
Urethritis.Urethritis commonly produces scant or profuse urethral discharge that's either thin and clear, mucoid, or thick and purulent. Other effects include urinary hesitancy, urgency, and frequency; dysuria; and itching and burning around the meatus.

Urinary incontinence:
Medical causes
(Nursing: Interpreting Signs and Symptoms)
Benign prostatic hyperplasia (BPH).Overflow incontinence is common with BPH as a result of urethral obstruction and urine retention. BPH begins with a group of signs and symptoms known as prostatism: reduced caliber and force of urine stream, urinary hesitancy, and a feeling of incomplete voiding. As obstruction increases, urination becomes more frequent, with nocturia and, possibly, hematuria. Examination reveals bladder distention and an enlarged prostate.
Bladder cancer.With bladder cancer, the patient commonly presents with urge incontinence and hematuria; obstruction by a tumor may produce overflow incontinence. The early stages may not produce symptoms. Other urinary signs and symptoms include frequency, dysuria, nocturia, dribbling, and suprapubic pain from bladder spasms after voiding. A mass may be palpable on bimanual examination.
Diabetic neuropathy.Autonomic neuropathy may cause painless bladder distention with overflow incontinence. Related findings include episodic constipation or diarrhea (which is commonly nocturnal), impotence and retrograde ejaculation, orthostatic hypotension, syncope, and dysphagia.
Multiple sclerosis (MS).Urinary incontinence, urgency, and frequency are common urologic findings in MS. In most patients, vision problems and sensory impairment occur early. Other findings include constipation, muscle weakness, paralysis, spasticity, hyperreflexia, intention tremor, ataxic gait, dysarthria, impotence, and emotional lability.
Prostate cancer.Urinary incontinence usually appears only in the advanced stages of prostate cancer. Urinary frequency and hesitancy, nocturia, dysuria, bladder distention, perineal pain, constipation, and a hard, irregularly shaped, nodular prostate are other common late findings.
Prostatitis (chronic).Urinary incontinence may occur as a result of urethral obstruction from an enlarged prostate. Other findings include urinary frequency and urgency, dysuria, hematuria, bladder distention, persistent urethral discharge, dull perineal pain that may radiate, ejaculatory pain, and decreased libido.
Spinal cord injury.Complete cord transection above the sacral level causes flaccid paralysis of the bladder. Overflow incontinence follows rapid bladder distention. Other findings include paraplegia, sexual dysfunction, sensory loss, muscle atrophy, anhidrosis, and loss of reflexes distal to the injury.
Stroke.With a stroke, urinary incontinence may be transient or permanent. Associated findings reflect the site and extent of the lesion and may include impaired mentation, emotional lability, behavioral changes, altered level of consciousness, and seizures. Headache, vomiting, visual deficits, and decreased visual acuity are possible. Sensorimotor effects include contralateral hemiplegia, dysarthria, dysphagia, ataxia, apraxia, agnosia, aphasia, and unilateral sensory loss.
Urethral stricture.Eventually, overflow incontinence may occur with a urethral stricture. As obstruction increases, urine extravasation may lead to formation of urinomas and urosepsis.
UTI.Besides incontinence, a UTI may produce urinary urgency, dysuria, hematuria, cloudy urine and, in males, urethral discharge. Bladder spasms or a feeling of warmth during urination may occur.
Other causes
Surgery.Urinary incontinence may occur after prostatectomy as a result of urethral sphincter damage.
