Hematuria (Blood in the Urine)

What is hematuria?

Hematuria is the presence of red blood cells (RBCs) in the urine. In microscopic hematuria, the urine appears normal to the naked eye, but examination with a microscope shows a high number of RBCs. Gross hematuria can be seen with the naked eye-the urine is red or the color of cola.

What causes hematuria?

Several conditions can cause hematuria, most of them not serious. For example, exercise may cause hematuria that goes away in 24 hours. Many people have hematuria without any other related problems. Often no specific cause can be found. But because hematuria may be the result of a tumor or other serious problem, a doctor should be consulted.

How is hematuria diagnosed?

To find the cause of hematuria, or to rule out certain causes, the doctor may order a series of tests, including urinalysis, blood tests, kidney imaging studies, and cystoscopic examination.

How is hematuria treated?

Treatment for hematuria depends on the cause. If no serious condition is causing the hematuria, no treatment is necessary.
