The cystoscope is inserted into your urethra and slowly advanced into the bladder . Thin surgical instruments can be inserted through the cystoscope. Procedures done with the help of these instruments may eliminate the need for more extensive surgery.
Cystoscopy may be done to evaluate problems that cannot be seen on imaging or to further investigate problems detected by ultrasound, intravenous pyelography or CT scan. Cystoscopy may also be done to remove tissue samples for biopsy, to remove foreign objects, to place ureteric stents to help urine flow from kidneys to the bladder, to remove urinary tract stones or growths, treat bleeding in the bladder, relieve blockages in the urethra, or treat or remove tumors.
It may also be done to place a catheter in the ureter for an X-ray test called retrograde pyelography. A dye that shows up on an X-ray picture is injected through the catheter to fill and outline the ureter and the inside of the kidney.
