HEMATURIA

Ask the Following Questions:

1. Is there abdominal pain? The presence of abdominal pain with hematuria should first suggest renal calculus, but other causes, such as renal embolism, renal contusion, or laceration, must be considered.
2. Is there dysuria or frequency of micturition associated with the hematuria? The presence of dysuria and frequency with the hematuria should suggest a bladder stone, prostatic disease, or a UTI.
3. Is there fever? The presence of fever with the hematuria would suggest pyelonephritis.
4. Is there a flank mass? The presence of bilateral flank masses with hematuria should suggest polycystic kidneys and hydronephrosis, whereas a unilateral flank mass would suggest a hypernephroma or unilateral hydronephrosis. A solitary cyst or renal vein thrombosis may also present with a flank mass and hematuria.
5. Is there hypertension? The presence of hypertension with the hematuria suggests glomerulonephritis, polycystic kidneys, and collagen diseases.
6. Are there other systemic signs and symptoms? If there are other systemic signs and symptoms, one should be looking for collagen disease, coagulation disorders, leukemia, and sickle cell anemia. When there is no hypertension or other signs and symptoms of systemic diseases, one should be looking for a benign or malignant tumor of the bladder, tuberculosis, or parasitic infection.

DIAGNOSTIC WORKUP

The workup begins with a urinalysis and microscopic examination of the urinary sediment. The physician can easily do this in his office. If there is proteinuria, granular cast, and red cell cast, glomerulonephritis or collagen disease should be suspected. A culture and sensitivity and colony count should be done if a UTI is suspected. A three-glass test may be done. If there is blood in the initial specimen, the cause is most likely in the urethra or male genitalia. If it is in the final specimen, the cause is most likely a bladder lesion. Phase-contrast microscopy may also be helpful in identifying hematuria from a glomerular lesion. If this is negative, an anaerobic culture should be done also and then an AFB smear and culture and guinea pig inoculation to rule out tuberculosis. An intravenous pyelogram will also usually have to be done. A CBC, sedimentation rate, chemistry panel, coagulation profile, and ANA test will help rule out blood dyscrasias, collagen diseases, and other systemic diseases. Ultrasonography may help diagnose a renal cyst.

If the above are not revealing, referral to a urologist is indicated. He will probably do a cystoscopy and retrograde pyelography. He may also want to order a CT scan of the abdomen and pelvis and a renal biopsy. Renal angiography and aortography may be necessary to evaluate renovascular hypertension and renal embolism.
