Hematuria (Blood in Urine)

What is hematuria?

Hematuria is the presence of red blood cells (RBC) in the urine, and is defined as gross or microscopic. Gross hematuria is a visible change in your urine color, where microscopic hematuria is when the red blood cells are visible only under a microscope. Some common causes of hematuria include kidney stones, infection, trauma, and cancer.


Evaluation includes an urine analysis, an urine culture, and a urine cytology. Imaging studies such as a CT scan or an ultrasound will be done, and a cystoscopy may be necessary to look inside the bladder.


The doctor will determine treatment based upon the cause of the hematuria.
