目的探讨4种输尿管镜入镜方法的成功率及对输尿管口的损伤。方法回顾性分析2008年7月-2011年3月间行输尿管镜手术的患者共553例,按其入镜方法分为4组,分别采用球囊扩张法、灌注泵加压灌注入镜法、内旋法及倒入法进行输尿管镜操作。分析其成功率及对输尿管口的损伤。结果气囊扩张法成功率为95%,但对输尿管口的损伤率为100%;灌注泵加压法成功率为67.5%,输尿管口损伤率为87.0%;内旋法的成功率为87.9%,损伤率为50.0%;倒入法成功率91.0%,对输尿管口损伤率为22.2%。4种方法中,灌注泵加压法一次性成功率最低,与其余3种方法比较,差异均有统计学意义(P<0.008);其余3种方法间一次性成功率差异无统计学意义(P>0.008)。对输尿管口的损伤率,4种方法组间两两比较的差异均有统计学意义(P<0.008),其中气囊扩张法损伤率最高,倒入法最低。结论倒入法是4种方法中成功率较高且损伤小的一种方法。
Objective To investigate the success rate of 4 kinds of ureteroscopy into the mirror and its damage to the ureter. Methods A total of 553 patients undergoing ureteroscopic surgery between July 2008 and March 2011 were retrospectively analyzed. The patients were divided into 4 groups according to their method of endoscopy. Balloon dilatation method, Internal rotation method and into the law for ureteroscopic operation. Analysis of its success rate and damage to the ureteral orifice. Results The success rate of balloon dilation was 95%, but the rate of damage to the ureter orifice was 100%. The success rate of perfusion pump pressurization was 67.5% and the ureteral orifice was 87.0%. The success rate of internal rotation was 87.9% The rate was 50.0%. The success rate of the infusion method was 91.0%, and the rate of ureteral orifice injury was 22.2%. Among the four methods, the one-off success rate of perfusion pump pressurization was the lowest, and the difference was statistically significant compared with the other three methods (P <0.008). There was no significant difference in one-off success rate among the other three methods P> 0.008). The rate of damage to the ureteral orifice was significantly different between the two groups (P <0.008). Among them, the rate of balloon dilatation injury was the highest, and the infusion method was the lowest. Conclusions The pour-in method is one of the four methods with high success rate and less damage.
