Interventions

SUREdevice

The SURE stone evacuation procedure is a technique intended to more easily and completely remove a kidney stone during a kidney stone treatment. The urologist first uses a laser to break the kidney stone into small pieces. Then with the SURE procedure, the pieces are gently vacuumed out of the kidney instead of retrieving the pieces one-by-one with a basket or leaving them to pass naturally in the urine. Basketing is allowed and might be used with the SURE procedure, if needed to remove some small stones.

Standard Ureteroscopy (Basketing)device

This is a treatment in which the urologist uses a laser to break a kidney stone into small pieces and then uses a tool called a basket to retrieve the pieces one at a time.
