When a stone has made its way out of the kidney and is close to the bladder or ureter in the lower part of the urinary tract, the most common procedure of removing it is through ureteroscopy. The surgeon may pass a ureteroscope (a hollow tube-like device) through the urinary tract to the location of the stone. A basket-like device is passed through the tube to grasp the stone, break it and withdraw the fragments through the tube.
No incisions are made in the body.
