Abstract:
Objective To investigate the clinical efficacy of flexible terminal suction ureteral access sheath(FTS-UAS)and ureteral access sheath(UAS)with disposable flexible ureteroscope(DFU)in the treatment of large load Kidney stones sized 2-4 cm.Methods We retrospectively analyzed clinical data from 238 patients who received FTS-UAS with DFU and UAS with DFU at Ruijin Hospital from January 2019 to October 2023.The observation group consisted of 125 patients who used the FTS-UAS with DFU,and the control group consisted of 113 patients who used the UAS with DFU.We compared the groups based on stone free rate(SFR),the overall complication rates,operating times,hospital stays,and postoperative inflammation.Results Surgeries on all 238 patients were successfully completed,with the stone clearance rates for the observation group and the control group being 90.40％and 75.22％respectively,a difference that was statistically significant(P＜0.05).All 238 surgeries were completed successfully.The observation group had a 90.40％SFR,while the control group had 75.22％,with the difference being statistically significant(P＜0.05).The overall complication rates were 1.6％in the observation group and 14.16％in the control group,a statistically significant difference(P＜0.001).The stone fragmentation and clearance took(101.17±25.64)minutes in the observation group and(86.23±20.35)minutes in the control group,also a significant difference(P＜0.05).Conclusion The FTS-UAS combined with DFU can improve SFR and has better safety in the treatment of 2-4 cm Kidney stones,despite longer fragmentation and clearance times compared to UAS.
