Hematuria or Blood in the Urine

Hematuria, or blood in the urine, is a relatively common condition that involves the abnormal presence of red blood cells in the urine. Microscopic hematuria, in which the urine appears normal to the naked eye, is often revealed through urine cultures during routine medical examinations. Gross hematuria can be seen with the naked eye when the urine appears red or rusty brown like tea or cola. Although both microscopic and gross hematuria can signal a serious medical condition, unexplained gross hematuria is often more concerning to the patient and the care provider.

Several conditions can cause hematuria, but most of them are not serious. Prescription medicines, vigorous exercise or even sexual intercourse may cause temporary hematuria that goes away naturally. Many people have microscopic hematuria without any other related problems. Because women and elderly adults are more vulnerable to urinary tract infections, they are also more likely to experience blood in the urine. But, because hematuria may be the result of kidney or bladder stones, a urinary tract infection, an enlarged prostrate, cancer or other serious medical problems, a physician should be consulted.

Testing for Hematuria or Blood in the Urine

  • Urinalysis
  • Urine culture
  • Blood tests
  • Cystoscopy
  • CT scan
  • Intravenous pyelogram
  • Abdominal ultrasound

Treatment for Hematuria

Treatment for hematuria depends on the physician's evaluation of the symptoms, medical history and cause. If no serious condition is causing the hematuria, no treatment is necessary. If a urinary tract infection is suspected, antibiotics may be prescribed.
