What Is Hematuria?

Hematuria is the presence of red blood cells (RBCs) in the urine. Often the urine appears normal to the naked eye, but examination under a microscope it reveals a high number of RBCs. This is known as microscopic hematuria. In gross hematuria, the urine is red or the color of cola, and can be seen with the naked eye.

In women, blood may appear to be in the urine when it is actually coming from the vagina. In men, what may be mistaken for urinary bleeding is sometimes a bloody ejaculation, usually due to a prostate problem. Always consult with your doctor if you see blood in your urine as a thorough evaluation will be needed. Your doctor will follow up on this problem to see if it persists and identify the cause. In children, hospitalization is often necessary to complete the work up.
