目的：探讨组合式输尿管软镜联合U100plus激光治疗上尿路结石的临床疗效及安全性。方法：应用组合式输尿管软镜联合U100plus激光治疗上尿路结石120例，记录手术时间、术中出血量等指标，观察并发症发生情况，计算单次碎石成功率，术后3月计算结石排净率。结果：单次碎石成功率88．3％，其中肾下盏结石单次碎石成功率66．7％，比其他部位单次碎石成功率低，具有统计学意义。手术时间47．7±30．5min ，术后血红蛋白下降1．7±1．5g／L ，11例患者出现发热，抗感染治疗后好转，未出现其他严重并发症。术后3月复查，结石排净率94．7％。结论：组合式输尿管软镜联合U100plus激光治疗直径＜2cm的上尿路结石是一种高效、安全的治疗方法。在降低部分操作性能的同时，降低了维护、使用成本，节约了维修成本及时间，为初次开展及经费紧张医院开展输尿管软镜技术提供了方便。%Objective:To evaluate the reliability and clinical efficiency of modular flexible ureteroscope combined with U100 plus laser lithotripsy for treatment of upper urinary tract calculi .Methods:A total of 120 cases with upper urinary tract calculi were treated with modular flexible ureteroscope combined with U100 plus laser litho‐tripsy in our department .Record the index with operation time ,hemorrhage volume ,etc .Observe the complication during and after the operation .Calculate the success rate of the single lithotripsy .Account the stone free rate 3 months after the operation .Results :The stone free rate was 88 .3% after one lithotripsy in these 120 cases .The single lithotripsy success rate of the lower calyx calculi was 66 .7% ,which is obviously lower than the other locations single lithotripsy success rate .The mean operation time was 47 .7 ± 30 .5min ,the average hemoglobin decreased 1 .7 ± 1 .5g/L after operation .11 patients had got fever ,but cured after anti‐infective therapy ,and without other severe complications .Review these cases 3 months later ,the stone free rate was 94 .7% after modular flexible ureteroscope lithotripsy .Conclusions :Modular flexible ureteroscope combined with U100 plus laser lithotripsy is an effective and safe treatment with the upper urinary tract calculi less than 2cm in diameters .Modular flexible ureteroscope de‐pressed the operating performance ,but ,meanwhile it can decrease the high use and maintenance costs .It can also decrease the repair time .It provides a convenience for the hospital which is short of money or the first time to carry out this technique .
