title: Use of a ureteral access sheath to facilitate removal of large stone burden during extracorporeal shock wave lithotripsy.
abstract: Large renal stone burdens within a nondilated collecting system in patients with a relative contraindication to percutaneous nephrolithotomy can be a challenging problem. We describe a novel technique using a ureteral access sheath combined with extracorporeal shock wave lithotripsy to facilitate passage of stone fragments in such patients.
