A TURP is done by means of a scope introduced through the urethra so there is no incision. The color of the urine will change according to how much bleeding occurs after surgery. The most common type of bleeding is from a venous source resulting in dark burgundy coloration with dark clots. This type of bleeding will typically stop on its own. Bright red urine with bright red clots is considered more aggressive and may require intervention. Drinking water will help flush the kidneys and/or bladder of bacteria and clots. A catheter is typically inserted after a TURP.
