Arm Intervention/treatment
Active Comparator: SURE Device: SURE
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.

Active Comparator: Standard Ureteroscopy (Basketing) Device: Standard Ureteroscopy (Basketing)
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.

Primary Outcome Measures :
