Hematuria (Blood in the Urine)

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 under 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.

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.

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

Urinalysis is the examination of urine for various cells and chemicals. In addition to finding RBCs, the doctor may find white blood cells that signal a urinary tract infection or casts (groups of cells molded together in the shape of the kidneys' tiny filtering tubes) that signal kidney disease. Excessive protein in the urine also signals kidney disease.

Blood tests may reveal kidney disease if the blood contains high levels of wastes that the kidneys are supposed to remove.

An intravenous pyelogram (IVP) is an x ray of the urinary tract. An IVP may reveal a tumor, a kidney or bladder stone, an enlarged prostate, or other blockage to the normal flow of urine.

A cystoscope can be used to take pictures of the inside of the bladder. It has a tiny camera at the end of a thin tube, which is inserted through the urethra. A cystoscope may provide a better view of a tumor or bladder stone than can be seen in an IVP.

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

Additional Information on Hematuria

The National Kidney and Urologic Diseases Information Clearinghouse collects resource information on kidney and urologic diseases for the Combined Health Information Database (CHID). CHID is a database produced by health-related agencies of the Federal Government. This database provides titles, abstracts, and availability information for health information and health education resources.

To provide you with the most up-to-date resources, information specialists at the clearinghouse created an automatic search of CHID. To obtain this information, you may view the results of the automatic search on Hematuria.

If you wish to perform your own search of the database, you may access the CHID Online website and search CHID yourself.
