Abstract:
Objective To evaluate the effectiveness and safety of flexible ureteroscopy lithotripsy (FURL) combined with holmium laser for the concurrent treatment of bilateral upper ureteral tract calculi.Methods The clinical data in 43 patients with bilateral upper ureteral tract calculi concurrently treated by FURL combined with holmium laser in our hospital from September 2014 to November 2016 were retrospectively analyzed.All cases conducted CT scanning before operation.The flexible ureteroscope was intraoperatively placed and the lithotripsy was conducted by using 200 μm optical fiber at a power of 0.8-1.0 J/10-20Hz,which was coordinated by reticular basket.After lithotripsy,bilateral urethral stents were placed.KUB or CT was re-examined on postoperative 1 d.The cases of residual stone were performed KUB again after removing urethral stent after 4-6 weeks.Results All cases were successfully placed the flexible ureteroscope by one time.The mean operation time was (101.5±37.2) min and the overall stone-free rate (SFR) was 81.4 ％ (35/43).SFR was 100％ in the patients with the stone burden less than 30 mm and 63.2％ in the patients with the stone burden ≥30 mm,the difference was statistically significant(P＜0.05).One case appeared fever (39.5 ℃) after operation,1 case developed subcapsular renal hematoma and no other severe complications occurred.Conclusion FURL combined with holmium laser is an effective means to concurrently treating bilateral upper ureteral calculi,especially for the patients with stone burden ＜30 mm,which has higher stone clearance rate with good safety.
