Brief Summary

Sepsis is a lethal complication of flexible ureteroscopy. The aim of this study is to identify predictors of sepsis after flexible ureteroscopy in patients with solitary proximal ureteral stones.

Outcome Measures

Primary Outcomes (1)

  • complication-sepsis

    sepsis is defined as the concurrence of infection and at least 2 of the following 4 criteria: (1) body temperature \>38°C, (2) heart rate \>90/minute, (3) respiratory rate \>20/minute, and (4) leukocyte count \<4,000 cells/μL or \>12,000 cells/μL

    within 48 hour after surgery

Study Arms (1)

proximal ureteral stone patient

Procedure: flexible ureteroscopy

Interventions

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.
