Hematuria is better known as Blood in Urine. There are two types of hematuria. Easily visualized blood is known as gross hematuria. There is also hematuria unseen by the naked eye, detected via microscopes known as microscopic hematuria. Hematuria may be caused by sexual activity, trauma, extensive exercise, and an infection such as urinary tract infection (UTI), the bladder or kidney stones and enlarged prostate. Other serious causes of hematuria include kidney and bladder cancer, polycystic kidney disease, kidney injury, blood clots, sickle cell disease, and inflammation of the kidneys, urethra bladder and prostate. Hematuria is diagnosed with a urinalysis, which tests the urine for blood via a dipstick. The dipstick patches on them change color determining whether there is presence of blood in the urine. Once it is confirmed that there is hematuria, the physician may send the remainder of urine for extra testing. The physician may also draw some blood, perform a biopsy of the kidney, or perform a cystoscopy to look into the bladder for causes of hematuria.
