Abstract:
Objective To compare the efficacy and safety of flexible vacuum-assisted ureteral access sheath(FV-UAS)plus flexible ureteroscopic lithotripsy(FURL)and percutaneous nephrolithotomy(PCNL)in the treatment of 2-3 cm lower calyx stones,so as to provide reference for clinical treatment options of this type of stones.Methods A retrospective analysis was conducted on 114 patients with lower calyx stones admitted to our hospital during May 2021 and May 2024.Based on the surgical approaches,the patients were divided into the FV-UAS-FURL group(n=57)and PCNL group(n=57).The general data,biochemical indicators,operation time,complication rate,stone-free rate(SFR)and other clinical data of the two groups were compared.Results There were no significant differences in the general data,SFR 1 day(70.2％vs.59.6％,P=0.239)and 1 month(84.2％vs.78.9％,P=0.469)(P＞0.05)after the surgery between the PCNL group and FV-UAS-FURL group.Compared to the PCNL group,the FV-UAS-FURL group had greater decrease in hemoglobin level[1.00(-6.00,6.00)g/L vs.4.50(0,12.75)g/L,P=0.010],shorter operation time[87.0(60.5,121.5)min vs.112.0(90.0,122.5)min,P=0.004],shorter hospital stay[1.0(1.0,4.0)d vs.8.0(6.5,10.0)d,P＜0.001],and lower incidence of postoperative hematuria(15.8％vs.31.6％,P=0.047)and fever(5.3％vs.22.8％,P=0.007).Conclusion Both PCNL and FV-UAS-FURL can safely and effectively treat 2-3 cm lower calyx stones.However,FV-UAS-FURL has advantages over PCNL,including fewer postoperative complications,shorter operation time,and shorter hospital stay,making it a better surgical choice.
