Hematuria or blood in the urine is one of the most common reasons why someone visits the urologist office. If blood in the urine is visible then it is termed gross hematuria. If blood is only detected on a urine test such as a urinalysis or a urine dipstick then it is termed microscopic hematuria.
Common Causes of Hematuria (Blood in urine)
Some of the common causes of blood in the urine include urinary tract infection, kidney stone, kidney disease, trauma, malignancies of the urinary tract, and medications such as blood thinners like Coumadin.
Evaluation for hematuria usually includes further laboratory studies that may include a repeat urinalysis and culture, urine cytology, upper urinary tract imaging with an renal-bladder ultrasound or abdominal / pelvic CAT scan (or CT urogram) as well as cystoscopy.
