You have undergone an endoscopy of your renal pelvis and ureter.

There are 2 kidneys in the body. There is one on each side of the spine just below the ribcage. Each kidney is made up of renal tissue and a renal pelvis. The renal tissue purifies the blood and, by doing so, produces urine. The urine gathers in the renal pelvis. The urinary passages include the ureters, bladder and urethra. Urine flows from both kidneys into the bladder via the ureters. The urethra channels the urine outward from the bladder.

Endoscopy is used to examine the inside of the renal pelvis and ureter. The procedure involves passing a thin scope or tube into the body, then advancing it to the renal pelvis and ureter. The tube or scope may be passed into the body through the opening in the urethra. However, access may also be obtained through an incision in the skin. Images from the examined area can be transmitted to the outside through the tube or scope. In this way, the inside of the renal pelvis and ureter can be viewed and assessed for any changes.
