What causes Glomerular Disease?
Article excerpts about the
causes of Glomerular Disease:
Glomerular diseases damage the glomeruli,
letting protein and sometimes red blood cells leak into the urine.
Sometimes a glomerular disease also interferes with the clearance of waste
products by the kidney, so they begin to build up in the blood.
Furthermore, loss of blood proteins like albumin in the urine can result
in a fall in their level in the bloodstream. In normal blood, albumin acts
like a sponge, drawing extra fluid from the body into the bloodstream,
where it remains until the kidneys remove it. But when albumin leaks into
the urine, the blood loses its capacity to absorb extra fluid from the
body. Fluid can accumulate outside the circulatory system in the face,
hands, feet, or ankles and cause swelling.

Hematuria:
Medical causes
(Handbook of Signs & Symptoms (Third Edition))
Bladder cancer
A primary cause of gross hematuria in men, bladder cancer may also produce pain in the bladder, rectum, pelvis, flank, back, or leg
Other common features are nocturia, dysuria, urinary frequency and urgency, vomiting, diarrhea, and insomnia.
Bladder trauma
Gross hematuria is characteristic in traumatic rupture or perforation of the bladder Typically, hematuria is accompanied by lower abdominal pain and, occasionally, anuria despite a strong urge to void
The patient may also develop swelling of the scrotum, buttocks, or perineum and signs of shock, such as tachycardia and hypotension.
Calculi
Bladder and renal calculi produce hematuria, which may be associated with signs of a urinary tract infection (UTI), such as dysuria and urinary frequency and urgency Bladder calculi usually cause gross hematuria, referred pain to the lower back or penile or vulvar area and, in some patients, bladder distention.
Renal calculi may produce microscopic or gross hematuria
The cardinal symptom, however, is colicky pain that travels from the CVA to the flank, suprapubic region, and external genitalia when a calculus is passed. The pain may be excruciating at its peak. Other signs and symptoms may include nausea and vomiting, restlessness, a fever, chills, abdominal distention and, possibly, decreased bowel sounds.
Coagulation disorders
Macroscopic hematuria is usually the first sign of hemorrhage in coagulation disorders, such as thrombocytopenia or disseminated intravascular coagulation
Other features include epistaxis, purpura (petechiae and ecchymoses), and signs of GI bleeding.
Cortical necrosis (acute)
Accompanying gross hematuria in acute cortical necrosis are intense flank pain, anuria, leukocytosis, and a fever.
Cystitis
Hematuria is a telling sign in all types of cystitis
Bacterial cystitis usually produces macroscopic hematuria with urinary urgency and frequency, dysuria, nocturia, and tenesmus. The patient complains of perineal and lumbar pain, suprapubic discomfort, and fatigue and occasionally has a low-grade fever.
More common in women, chronic interstitial cystitis occasionally causes grossly bloody hematuria. Associated features include urinary frequency, dysuria, nocturia, and tenesmus. Microscopic and macroscopic hematuria may occur with tubercular cystitis, which may also cause urinary urgency and frequency, dysuria, tenesmus, flank pain, fatigue, and anorexia. Viral cystitis usually produces hematuria, urinary urgency and frequency, dysuria, nocturia, tenesmus, and a fever.
Diverticulitis
When diverticulitis involves the bladder, it usually causes microscopic hematuria, urinary frequency and urgency, dysuria, and nocturia
Characteristic findings include left lower quadrant pain, abdominal tenderness, constipation or diarrhea and, at times, a palpable, firm, fixed, and tender abdominal mass The patient may also develop mild nausea, flatulence, and a low-grade fever.
Glomerulonephritis
Acute glomerulonephritis usually begins with gross hematuria that tapers off to microscopic hematuria and red cell casts, which may persist for months It may also produce oliguria or anuria, proteinuria, a mild fever, fatigue, flank and abdominal pain, generalized edema, increased blood pressure, nausea, vomiting, and signs of lung congestion, such as crackles and a productive cough.
Chronic glomerulonephritis usually causes microscopic hematuria accompanied by proteinuria, generalized edema, and increased blood pressure
Signs and symptoms of uremia may also occur in advanced disease.
Nephritis (interstitial)
Typically, nephritis causes microscopic hematuria However, the patient with acute interstitial nephritis may develop gross hematuria. Other findings are a fever, a maculopapular rash, and oliguria or anuria. In chronic interstitial nephritis, the patient has dilute — almost colorless — urine that may be accompanied by polyuria and increased blood pressure.
Nephropathy (obstructive)
Obstructive nephropathy may cause microscopic or macroscopic hematuria, but urine is rarely grossly bloody The patient may report colicky flank and abdominal pain, CVA tenderness, and anuria or oliguria that alternates with polyuria.
Polycystic kidney disease
Polycystic kidney disease is a hereditary disorder that may cause recurrent microscopic or gross hematuria
Although commonly asymptomatic before age 40, it may cause increased blood pressure, polyuria, dull flank pain, and signs of a UTI, such as dysuria and urinary frequency and urgency Later, the patient develops a swollen, tender abdomen and lumbar pain that’s aggravated by exertion and relieved by lying down
He may also have proteinuria and colicky abdominal pain from the ureteral passage of clots or stones.
Prostatitis
Whether acute or chronic, prostatitis may cause macroscopic hematuria, usually at the end of urination It may also produce urinary frequency and urgency and dysuria followed by visible bladder distention.
Acute prostatitis also produces fatigue, malaise, myalgia, polyarthralgia, a fever with chills, nausea, vomiting, perineal and low back pain, and a decreased libido
Rectal palpation reveals a tender, swollen, boggy, firm prostate.
Chronic prostatitis commonly follows an acute attack. It may cause persistent urethral discharge, dull perineal pain, ejaculatory pain, and a decreased libido.
Pyelonephritis (acute)
Acute pyelonephritis typically produces microscopic or macroscopic hematuria that progresses to grossly bloody hematuriaAfter the infection resolves, microscopic hematuria may persist for a few months. Related signs and symptoms include a persistent high fever, unilateral or bilateral flank pain, CVA tenderness, shaking chills, weakness, fatigue, dysuria, urinary frequency and urgency, nocturia, and tenesmus. The patient may also exhibit nausea, anorexia, vomiting, and signs of paralytic ileus, such as hypoactive or absent bowel sounds and abdominal distention.
Renal cancer
The classic triad of signs and symptoms includes grossly bloody hematuria; dull, aching flank pain; and a smooth, firm, palpable flank mass
Colicky pain may accompany the passage of clots Other findings include a fever, CVA tenderness, and increased blood pressure
In advanced disease, the patient may develop weight loss, nausea and vomiting, and leg edema with varicoceles.
Renal infarction
Typically, renal infarction produces gross hematuria The patient may complain of constant, severe flank and upper abdominal pain accompanied by CVA tenderness, anorexia, and nausea and vomiting
Other findings include oliguria or anuria, proteinuria, hypoactive bowel sounds and, a day or two after infarction, a fever and increased blood pressure.
Renal papillary necrosis (acute)
Acute renal papillary necrosis usually produces grossly bloody hematuria, which may be accompanied by intense flank pain, CVA tenderness, abdominal rigidity and colicky pain, oliguria or anuria, pyuria, fever, chills, vomiting, and hypoactive bowel sounds Arthralgia and hypertension are common.
Renal trauma
About 80% of patients with renal trauma have microscopic or gross hematuria Accompanying signs and symptoms may include flank pain, a palpable flank mass, oliguria, hematoma or ecchymoses over the upper abdomen or flank, nausea and vomiting, and hypoactive bowel sounds
Severe trauma may precipitate signs of shock, such as tachycardia and hypotension.
Renal tuberculosis
Gross hematuria is commonly the first sign of renal tuberculosis It may be accompanied by urinary frequency, dysuria, pyuria, tenesmus, colicky abdominal pain, lumbar pain, and proteinuria.
Renal vein thrombosis
Grossly bloody hematuria usually occurs in renal vein thrombosis In abrupt venous obstruction, the patient experiences severe flank and lumbar pain as well as epigastric and CVA tenderness
Other features include a fever, pallor, proteinuria, peripheral edema and, when the obstruction is bilateral, oliguria or anuria and other uremic signs. The kidneys are easily palpable. Gradual venous obstruction causes signs of nephrotic syndrome, proteinuria and, occasionally, peripheral edema.
Schistosomiasis
Schistosomiasis usually causes intermittent hematuria at the end of urination It may be accompanied by dysuria, colicky renal and bladder pain, and palpable lower abdominal masses.

Urethral trauma
Initial hematuria may occur, possibly with blood at the urinary meatus, local pain, and penile or vulvar ecchymoses.
Vasculitis
Hematuria is usually microscopic in vasculitis Associated signs and symptoms include malaise, myalgia, polyarthralgia, a fever, increased blood pressure, pallor and, occasionally, anuria
Other features, such as urticaria and purpura, may reflect the etiology of vasculitis.
Other causes
Diagnostic tests
Renal biopsy is the diagnostic test most commonly associated with hematuria This sign may also result from biopsy or manipulative instrumentation of the urinary tract such as in cystoscopy.
Drugs
Drugs that commonly cause hematuria are anticoagulants, aspirin (toxicity), analgesics, cyclophosphamide, metyrosine, phenylbutazone, oxyphenbutazone, penicillin, rifampin, and thiabendazole.
Herb alert
When taken with an anticoagulant, herbal remedies, such as garlic and ginkgo biloba, can cause adverse reactions, including excessive bleeding and hematuria.
Treatments
Any therapy that involves manipulative instrumentation of the urinary tract, such as transurethral prostatectomy, may cause microscopic or macroscopic hematuria Following a kidney transplant, a patient may experience hematuria with or without clots, which may require indwelling urinary catheter irrigation.

Nephrotic syndrome:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
About 75% of nephrotic syndrome cases result from primary (idiopathic) glomerulonephritis. Classifications include:
❑ In lipid nephrosis (nil lesions), the main cause of nephrotic syndrome in children, the glomerulus looks normal by light microscopy. Some tubules may contain increased lipid deposits.
❑ Membranous glomerulonephritis, the most common lesion in adult idiopathic nephrotic syndrome, is characterized by uniform thickening of the glomerular basement membrane containing dense deposits and eventually progresses to renal failure.
❑ Focal glomerulosclerosis can develop spontaneously at any age, follow renal transplantation, or result from heroin abuse. Reported incidence of this condition is 10% in children with nephrotic syndrome and up to 20% in adults. Lesions initially affect the deeper glomeruli, causing hyaline sclerosis, with later involvement of the superficial glomeruli. These lesions generally cause slowly progressive deterioration in renal function. Remissions occur occasionally.
❑ In membranoproliferative glomerulonephritis, slowly progressive lesions develop in the subendothelial region of the basement membrane. Lesions may follow infection, particularly streptococcal infection. This disease occurs primarily in children and young adults.
Other causes of nephrotic syndrome include metabolic diseases such as diabetes mellitus; collagen-vascular disorders, such as systemic lupus erythematosus and periarteritis nodosa; circulatory diseases, such as heart failure, sickle cell anemia, and renal vein thrombosis; nephrotoxins, such as mercury, gold, and bismuth; allergic reactions; and infections, such as tuberculosis or enteritis. Other possible causes are pregnancy, hereditary nephritis, multiple myeloma, and other neoplastic diseases. These diseases increase glomerular protein permeability, leading to increased urinary excretion of protein, especially albumin, and subsequent hypoalbuminemia.
Nephrotic patients have an increased risk of infection, particularly of peritonitis.

After the infection resolves, microscopic hematuria may persist for a few months. Related signs and symptoms include persistent high fever, unilateral or bilateral flank pain, CVA tenderness, shaking chills, weakness, fatigue, dysuria, urinary frequency and urgency, nocturia, and tenesmus. The patient may also exhibit nausea, anorexia, vomiting, and signs of paralytic ileus, such as hypoactive or absent bowel sounds and abdominal distention.
The classic triad of signs and symptoms of renal cancer includes grossly bloody hematuria; dull, aching flank pain; and a smooth, firm, palpable flank mass. Colicky pain may accompany the passage of clots. Other findings include fever, CVA tenderness, and increased blood pressure. In advanced disease, the patient may develop weight loss, nausea and vomiting, and leg edema with varicoceles.
Typically, this disorder produces gross hematuria. The patient may complain of constant, severe flank and upper abdominal pain accompanied by CVA tenderness, anorexia, and nausea and vomiting. Other findings include oliguria or anuria, proteinuria, hypoactive bowel sounds and, a day or two after infarction, fever and increased blood pressure.
Acute renal papillary necrosis usually produces grossly bloody hematuria, which may be accompanied by intense flank pain, CVA tenderness, abdominal rigidity and colicky pain, oliguria or anuria, pyuria, fever, chills, vomiting, and hypoactive bowel sounds. Arthralgia and hypertension are common.
About 80% of patients with renal trauma have microscopic or gross hematuria. Accompanying signs and symptoms may include flank pain, a palpable flank mass, oliguria, hematoma or ecchymoses over the upper abdomen or flank, nausea and vomiting, and hypoactive bowel sounds. Severe trauma may precipitate signs of shock, such as tachycardia and hypotension.
Gross hematuria is often the first sign of renal tuberculosis. It may be accompanied by urinary frequency, dysuria, pyuria, tenesmus, colicky abdominal pain, lumbar pain, and proteinuria.
Grossly bloody hematuria usually occurs in renal vein thrombosis. In abrupt venous obstruction, the patient experiences severe flank and lumbar pain as well as epigastric and CVA tenderness. Other features include fever, pallor, proteinuria, peripheral edema and, when the obstruction is bilateral, oliguria or anuria and other uremic signs. The kidneys are easily palpable. Gradual venous obstruction causes signs of nephrotic syndrome, proteinuria and, occasionally, peripheral edema.
In this hereditary disorder, gross hematuria may result from congestion of the renal papillae. Associated signs and symptoms of sickle cell anemia may include pallor, dehydration, chronic fatigue, polyarthralgia, leg ulcers, dyspnea, chest pain, impaired growth and development, hepatomegaly and, possibly, jaundice. Auscultation reveals tachycardia and systolic and diastolic murmurs.
Gross hematuria and proteinuria may occur when systemic lupus erythematosus (SLE) involves the kidneys. Cardinal associated features include nondeforming joint pain and stiffness, a butterfly rash, photosensitivity, Raynaud’s phenomenon, seizures or psychoses, recurrent fever, lymphadenopathy, oral or nasopharyngeal ulcers, anorexia, and weight loss.
With urethral trauma, initial hematuria may occur, possibly with blood at the urinary meatus, local pain, and penile or vulvar ecchymoses.
When vaginitis spreads to the urinary tract, it may produce macroscopic hematuria. Related signs and symptoms may include urinary frequency and urgency, dysuria, nocturia, perineal pain, pruritus, and a malodorous vaginal discharge.
Hematuria is usually microscopic in vasculitis. Associated signs and symptoms include malaise, myalgia, polyarthralgia, fever, increased blood pressure, pallor and, occasionally, anuria. Other features, such as urticaria and purpura, may reflect the etiology of vasculitis.
Renal biopsy is the diagnostic test most often associated with hematuria. This sign may also result from biopsy or manipulative instrumentation of the urinary tract, as in cystoscopy.
Drugs that commonly cause hematuria are anticoagulants, aspirin toxicity, analgesics, cyclophosphamide, metyrosine, phenylbutazone, penicillin, rifampin, and thiabendazole.
Any therapy that involves manipulative instrumentation of the urinary tract, such as transurethral prostatectomy, may cause microscopic or macroscopic hematuria. Following a kidney transplant a patient may experience hematuria with or without clots, which may require indwelling urinary catheter irrigation.

Bladder cancer.A primary cause of gross hematuria in men, bladder cancer may also produce pain in the bladder, rectum, pelvis, flank, back, or leg. Other common features are nocturia, dysuria, urinary frequency and urgency, vomiting, diarrhea, and insomnia.
Bladder trauma.Gross hematuria is characteristic in traumatic rupture or perforation of the bladder. Typically, hematuria is accompanied by lower abdominal pain and, occasionally, anuria despite a strong urge to void. The patient may also develop swelling of the scrotum, buttocks, or perineum and signs of shock, such as tachycardia and hypotension.
Calculi.Bladder and renal calculi produce hematuria, which may be associated with signs of a urinary tract infection (UTI), such as dysuria and urinary frequency and urgency. Bladder calculi usually cause gross hematuria, referred pain to the lower back or penile or vulvar area and, in some patients, bladder distention.
Renal calculi may produce microscopic or gross hematuria. The cardinal symptom, however, is colicky pain that travels from the CVA to the flank, suprapubic region, and external genitalia when a calculus is passed. The pain may be excruciating at its peak. Other signs and symptoms may include nausea and vomiting, restlessness, a fever, chills, abdominal distention and, possibly, decreased bowel sounds.
Coagulation disorders.Macroscopic hematuria is usually the first sign of hemorrhage in coagulation disorders, such as thrombocytopenia or disseminated intravascular coagulation. Other features include epistaxis, purpura (petechiae and ecchymoses), and signs of GI bleeding.
Cortical necrosis (acute).Accompanying gross hematuria in acute cortical necrosis are intense flank pain, anuria, leukocytosis, and a fever.
Cystitis.Hematuria is a telling sign in all types of cystitis. Bacterial cystitis usually produces macroscopic hematuria with urinary urgency and frequency, dysuria, nocturia, and tenesmus. The patient complains of perineal and lumbar pain, suprapubic discomfort, and fatigue and occasionally has a low-grade fever.
More common in women, chronic interstitial cystitis occasionally causes grossly bloody hematuria. Associated features include urinary frequency, dysuria, nocturia, and tenesmus. Microscopic and macroscopic hematuria may occur with tubercular cystitis, which may also cause urinary urgency and frequency, dysuria, tenesmus, flank pain, fatigue, and anorexia. Viral cystitis usually produces hematuria, urinary urgency and frequency, dysuria, nocturia, tenesmus, and a fever.
Diverticulitis.When diverticulitis involves the bladder, it usually causes microscopic hematuria, urinary frequency and urgency, dysuria, and nocturia. Characteristic findings include left lower quadrant pain, abdominal tenderness, constipation or diarrhea and, at times, a palpable, firm, fixed, and tender abdominal mass. The patient may also develop mild nausea, flatulence, and a low-grade fever.
Glomerulonephritis.Acute glomerulonephritis usually begins with gross hematuria that tapers off to microscopic hematuria and red cell casts, which may persist for months. It may also produce oliguria or anuria, proteinuria, a mild fever, fatigue, flank and abdominal pain, generalized edema, increased blood pressure, nausea, vomiting, and signs of lung congestion, such as crackles and a productive cough.
Chronic glomerulonephritis usually causes microscopic hematuria accompanied by proteinuria, generalized edema, and increased blood pressure. Signs and symptoms of uremia may also occur in advanced disease.
Nephritis (interstitial).Typically, nephritis causes microscopic hematuria. However, the patient with acute interstitial nephritis may develop gross hematuria. Other findings are a fever, a maculopapular rash, and oliguria or anuria. In chronic interstitial nephritis, the patient has dilute—almost colorless—urine that may be accompanied by polyuria and increased blood pressure.
Nephropathy (obstructive).Obstructive nephropathy may cause microscopic or macroscopic hematuria, but urine is rarely grossly bloody. The patient may report colicky flank and abdominal pain, CVA tenderness, and anuria or oliguria that alternates with polyuria.
Polycystic kidney disease.Polycystic kidney disease is a hereditary disorder that may cause recurrent microscopic or gross hematuria. Although it commonly produces no symptoms before age 40, it may cause increased blood pressure, polyuria, dull flank pain, and signs of a UTI, such as dysuria and urinary frequency and urgency. Later, the patient develops a swollen, tender abdomen and lumbar pain that's aggravated by exertion and relieved by lying down. He may also have proteinuria and colicky abdominal pain from the ureteral passage of clots or calculi.
Prostatitis.Whether acute or chronic, prostatitis may cause macroscopic hematuria, usually at the end of urination. It may also produce urinary frequency and urgency and dysuria followed by visible bladder distention.
Acute prostatitis also produces fatigue, malaise, myalgia, polyarthralgia, a fever with chills, nausea, vomiting, perineal and low back pain, and a decreased libido. Rectal palpation reveals a tender, swollen, boggy, firm prostate.
Chronic prostatitis commonly follows an acute attack. It may cause persistent urethral discharge, dull perineal pain, ejaculatory pain, and a decreased libido.
Pyelonephritis (acute).Acute pyelonephritis typically produces microscopic or macroscopic hematuria that progresses to grossly bloody hematuria. After the infection resolves, microscopic hematuria may persist for a few months. Related signs and symptoms include a persistent high fever, unilateral or bilateral flank pain, CVA tenderness, shaking chills, weakness, fatigue, dysuria, urinary frequency and urgency, nocturia, and tenesmus. The patient may also exhibit nausea, anorexia, vomiting, and signs of paralytic ileus, such as hypoactive or absent bowel sounds and abdominal distention.
Renal cancer.The classic triad of signs and symptoms of renal cancer includes grossly bloody hematuria; dull, aching flank pain; and a smooth, firm, palpable flank mass. Colicky pain may accompany the passage of clots. Other findings include a fever, CVA tenderness, and increased blood pressure. In advanced disease, the patient may develop weight loss, nausea and vomiting, and leg edema with varicoceles.
Renal infarction.Typically, renal infarction produces gross hematuria. The patient may complain of constant, severe flank and upper abdominal pain accompanied by CVA tenderness, anorexia, and nausea and vomiting. Other findings include oliguria or anuria, proteinuria, hypoactive bowel sounds and, a day or two after infarction, a fever and increased blood pressure.
Renal papillary necrosis (acute).Acute renal papillary necrosis usually produces grossly bloody hematuria, which may be accompanied by intense flank pain, CVA tenderness, abdominal rigidity and colicky pain, oliguria or anuria, pyuria, fever, chills, vomiting, and hypoactive bowel sounds. Arthralgia and hypertension are common.
Renal trauma.About 80% of patients with renal trauma have microscopic or gross hematuria. Accompanying signs and symptoms may include flank pain, a palpable flank mass, oliguria, hematoma or ecchymoses over the upper abdomen or flank, nausea and vomiting, and hypoactive bowel sounds. Severe trauma may precipitate signs of shock, such as tachycardia and hypotension.
Renal tuberculosis.Gross hematuria is commonly the first sign of renal tuberculosis. It may be accompanied by urinary frequency, dysuria, pyuria, tenesmus, colicky abdominal pain, lumbar pain, and proteinuria.
Renal vein thrombosis.Grossly bloody hematuria usually occurs in renal vein thrombosis. In abrupt venous obstruction, the patient experiences severe flank and lumbar pain as well as epigastric and CVA tenderness. Other features include a fever, pallor, proteinuria, peripheral edema and, when the obstruction is bilateral, oliguria or anuria and other uremic signs. The kidneys are easily palpable. Gradual venous obstruction causes signs of nephrotic syndrome, proteinuria and, occasionally, peripheral edema.
Schistosomiasis.Schistosomiasis usually causes intermittent hematuria at the end of urination. It may be accompanied by dysuria, colicky renal and bladder pain, and palpable lower abdominal masses.
Sickle cell anemia.Sickle cell anemia is a hereditary disorder in which gross hematuria may result from congestion of the renal papillae. Associated signs and symptoms may include pallor, dehydration, chronic fatigue, polyarthralgia, leg ulcers, dyspnea, chest pain, impaired growth and development, hepatomegaly and, possibly, jaundice. Auscultation reveals tachycardia and systolic and diastolic murmurs.
Systemic lupus erythematosus (SLE).Gross hematuria and proteinuria may occur when SLE involves the kidneys. Cardinal associated features include nondeforming joint pain and stiffness, a butterfly rash, photosensitivity, Raynaud's phenomenon, seizures or psychoses, a recurrent fever, lymphadenopathy, oral or nasopharyngeal ulcers, anorexia, and weight loss.
Urethral trauma.Initial hematuria may occur, possibly with blood at the urinary meatus, local pain, and penile or vulvar ecchymoses.
Vasculitis.Hematuria is usually microscopic in vasculitis. Associated signs and symptoms include malaise, myalgia, polyarthralgia, a fever, increased blood pressure, pallor and, occasionally, anuria. Other features, such as urticaria and purpura, may reflect the etiology of vasculitis.
Diagnostic tests.Renal biopsy is the diagnostic test most commonly associated with hematuria. This sign may also result from biopsy or manipulative instrumentation of the urinary tract such as in cystoscopy.
Drugs.Drugs that commonly cause hematuria are anticoagulants, aspirin (toxicity), analgesics, cyclophosphamide, metyrosine, phenylbutazone, oxyphenbutazone, penicillin, rifampin, and thiabendazole.
Treatments.Any therapy that involves manipulative instrumentation of the urinary tract, such as transurethral prostatectomy, may cause microscopic or macroscopic hematuria. Following a kidney transplant, a patient may experience hematuria with or without clots, which may require indwelling urinary catheter irrigation.
