In a ureteroscopy, the surgeon passes a thin viewing instrument (ureteroscope) through the tube from the bladder out of the body (urethra) into the bladder, and then into the ureter to the location of the kidney stone. No incisions are made in the body.
Your surgeon removes the kidney stone using forceps or an instrument with a small "basket." Smaller stones can be removed all in one piece. Larger stones may need to be broken up before the surgeon can remove them.
