Hematuria is the medical name for blood in the urine. Hematuria can be visible (called gross), or only visible by a microscope. There are many causes of hematuria including infections, inflammation, trauma, stones, and tumors. Dr. Reznicek from Pacific Northwest Urology Specialists describes some of the many causes of hematuria as well as the recommended workup.

Workup usually consists of imaging of the kidneys and the bladder and then a cystoscopic examination (camera into the bladder).
