Overview

Seeing blood in your urine can be alarming. While in many instances the cause is harmless, blood in urine (hematuria) can indicate a serious disorder.

Blood that you can see is called gross hematuria. Urinary blood that's visible only under a microscope (microscopic hematuria) is found when your doctor tests your urine. Either way, it's important to determine the reason for the bleeding.

Treatment depends on the cause.
