title: Expanding use of ureteral access sheath for stones larger than access sheath's internal diameter.
abstract: The internal diameter of the ureteral access sheath limits the size of stones that can be removed during flexible ureteroscopy. We describe a technique that allows removal of larger stones, which are entrapped and removed en bloc with the access sheath. This new technique was shown to be efficient and safe.
