Definition

A procedure that uses a ureteroscope to look inside the ureter (tube that connects the bladder to the kidney) and the renal pelvis (part of the kidney that collects urine and funnels it into the ureter). A ureteroscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue to be checked under a microscope for signs of disease. The ureteroscope is inserted through the urethra into the bladder, ureter, and renal pelvis. Ureteroscopy may be used to check for cancer or other abnormal growths in the ureter and renal pelvis and to treat stones in the kidney or ureter.
