The Analysis Of Curative Effect Of Simultaneous And Staged Bilateral Flexible Ureteroscopy Lithotripsy For Bilateral Renal Stones

Objective To analyze the safety and efficacy of simultaneous bilateral flexible ureteroscopy lithotripsy(SB-FURL)for bilateral renal stones.Methods A retrospective analysis of 101 patients who underwent bilateral flexible ureteroscopy lithotripsy in the hospital from April 2015 to May 2017.76 of them meet the research criteria,39 patients who underwent SB-FURL and 37 patients who underwent Staged bilateral FURL were selected into simultaneous group and staged group respectively.The Stone Free Rate(SFR)1 month after surgery,overall operative time,overall hospital stay and complication rate between two groups were compared.Results The patients' surgeries of two groups were completed successfully.No significant difference found between two groups about overall operative time,complication rate and SFR(P>0.05).While the SB-FURL group's median of overall hospital stay was significantly shorter than staged bilateral FURL group(P < 0.05).No ureteral perforation and ureteral mucosal avulsion occurred in surgeries in the two groups,and there were no serious complications of urinogenic sepsis and renal insufficiency after surgeries.Conclusion SB-FURL is safe and effective in the treatment of bilateral renal calculi in select patients.
