Cystoscopy is a procedure that allows the surgeon to see directly into the lower urinary tract (bladder and urethra). A lighted, tubular telescope-like instrument called a cystoscope is placed into the bladder through the urethra.
This test is done for many reasons. It is to look for problems associated with bleeding or pain. It can be done to look for obstruction of the urinary tract or to look for kidney stones. It can also be used to detect problems with the lining of the bladder.
Water flows through the cystoscope so the surgeon can see the bladder, urethra and the insertion of the ureters into the bladder. X-rays may be done along with cystoscopy to look for different problems with the ureter or kidney. It is done under general anesthesia so your child will feel no pain.
