title: A new application for the removal of caliceal renal stones with the rigid ureteropyeloscope.
abstract: Stone migration into the kidney can result in failure to remove a ureteral stone with a ureteroscope. A new application with the rigid ureteropyeloscope was used to remove a ureteral stone that had migrated into a lower renal calix. Under fluoroscopic control a 9F catheter was advanced next to the stone through the emptied sheath of the ureteropyeloscope whose tip was in the upper ureter. Then a basket was placed through the catheter and was used to trap and remove the stone.
