If a patient has a stone lodged in the ureter, Loma Linda University Medical Center urologists may recommend a ureteroscopy. The ureter is the tube that carries urine from the kidneys, to the bladder and in a ureteroscopy, the surgeon passes a thin viewing instrument called a ureteroscopy through the urethra and into the bladder.

The surgeon then moves the scope up into the ureter. This allows the surgeon to see the small stone or stones that have passed from the kidneys and become stuck in the ureter. While the passing of stones, particularly when they become lodged in a narrow ureter or urethra can be extremely painful, this procedure is performed when the patient is fully asleep under general anesthesia. There are no incisions made during a ureteroscopy.

Procedure Details
Once the afflicting stones have been located, the surgeon will use laser energy to break up the stones. They will then pass through the urethra. A small tube called a stent will be left in the ureter for up to two weeks to enhance healing. Ureteroscopy is an outpatient procedure at Loma Linda University Medical Center and typically does not require overnight hospitalization.
