If you have a stone lodged in your ureter or have an area that needs more study in your ureter, Dr. Friedman may recommend a ureteroscopy, usually with general or regional anesthesia.

The ureter is the tube that carries urine fro the  kidney to the bladder. The ureteroscope is a special, very thin instrument used to look directly at and visualize the inside of the ureter.

Some ureteroscopes are flexible like a small, very long straw. Others are more rigid and firm.

Through the ureteroscope, the doctor can see the stone. The doctor can then remove the stone, either by removing it with a small basket at the end of the wire inserted through an extra tube in the ureteroscope or by extending a flexible fiber that carries a laser beam to break the stone into smaller pieces that can then pass out of the body in your urine.

How and what the doctor will do is determined by the location, size, and composition of the stone. The doctor may leave a stent, a flexible tube that keeps the ureter open for drainage after the procedure.
