Abstract:
Objective To evaluate the therapeutic efficacy of a novel ureterorenoscope(Sotn ureterorenoscope)combined with flexible ureteroscope in the management of ureteral long-term incarcerated stones.Methods From June 2019 to January 2024,116 cases of ureteral incarcerated stones that had developed for over 1 year were treated in our department.Among them,45 cases were treated by using the Sotn ureterorenoscope combined with flexible ureteroscope(Sotn group),and 71 cases were given rigid ureteroscopy with flexible ureteroscopy(regular group).In the Sotn group,a standard endoscope and a rigid ureteral channel sheath were inserted under direct vision.With the sheath indwelled,a lithotripsy endoscope was replaced for stone fragmentation and removal.If the stone moved up,a flexible ureteroscope was inserted to explore the renal pelvis for lithotripsy.In the regular group,a rigid ureteroscope was used to explore the affected ureter for lithotripsy.If the stone moved up during the lithotripsy process,a sheath was inserted and the ureteroscope was replaced for lithotripsy.The operation time,surgical bleeding volume,incidence of postoperative complications,stone-free rate after operation,and postoperative hospital stay were compared between the two groups.Results There were no statistically significant differences in operation time,surgical bleeding volume,and postoperative hospital stay between the two groups(P＞0.05).The incidence of postoperative complications(back pain,fever,nausea and vomiting)in the Sotn group was lower than that in the regular group[15.6％(7/45)vs.33.8％(24/71),x2=4.683,P=0.030;6.7％(3/45)vs.26.8％(19/71),x2=7.236,P=0.007;4.4％(2/45)vs.23.9％(17/71),x2=7.646,P=0.006].The instant stone-free rate(at day 1 after operation)in the Sotn group was significantly higher than that in the regular group[51.1％(23/45)vs.16.9％(12/71),x2=15.299,P=0.000].Conclusion The Sotn ureterorenoscope has lower incidence of postoperative complications and higher instant stone-free rate in the treatment of long-term incarcerated ureteral stones,which is a safe and effective surgical technique.
