proximal ureteral stone patient
flexible ureteroscopy
flexible ureteroscopy is used to removed the stone. If a double-J stent was inserted pre-operatively, it was removed at the beginning of surgery. Rigid ureteroscopy was routinely used for ureteral dilatation before fURS. A 0.035 mm guidewire was advanced through the urethral and ureteral meatuses to the renal pelvis under direct rigid ureteroscope vision. A 14-Fr ureteral access sheath (Cook Medical, Bloomington, IN) was then passed over the wire to the ureteropelvic junction, and 7.5-Fr fURS (Flex-X2, Karl Storz, Germany) was performed through the sheath. Intrarenal pressure was stabilized by a pressure-sensitive pump (Shenda Medical, China). Holmium: yttrium-aluminum-garnet laser was used to fragment the stones. After lithotripsy, 6-Fr double-J stent was routinely inserted in all cases for 2-4 weeks.
