摘要/Abstract

摘要： 目的探讨利用钬激光低频低能联合输尿管导管引流，在输尿管上段结石输尿管镜钬激光碎石术的疗效。
方法 2017年9月～2019年9月我院行输尿管镜钬激光碎石治疗的输尿管上段结石病人120例，根据术中是否使用输尿管导管引流，分为两组，常规碎石组52例，未使用输尿管导管引流；导管引流碎石组68例，采用输尿管导管引流。在导管引流碎石组中，根据钬激光的能量频率，分为高频高能组(33例)和低频低能组(35例)。统计各组的手术时间，术后结石移位率和术后残石率。
结果导管引流碎石组的手术时间为(35.4±5.5)分钟，常规碎石组为(37.6±5.9)分钟，两组比较差异有统计学意义(P<0.05)。导管引流碎石组术后结石移位率为17.6%，常规碎石组为34.6%，低频低能组为11.4%，高频高能组为24.2%，两组比较差异有统计学意义(P<0.05)。
结论钬激光低频低能联合输尿管导管引流，在输尿管镜钬激光碎石术治疗输尿管上段结石，能有效降低术后结石移位率和残石率，并能缩短手术时间。

Abstract: Objective To investigate the efficacy of low rate,low energy of holmium laser combined with ureteral catheter in ureteroscopic lithotripsy to treat upper ureteral calculi.
Methods The clinical data of 120 patients with upper ureteral calculi performed with ureteroscopic lithotripsy from Sep.2017 to Sep.2019 was retrospectively alalyzed.The patients were divided into routine lithotripsy group(without catheter drainage，52 cases) and catheter drainage group(68 cases).The catheter drainage group was divided into high rate,high energy group(33 cases) and low rate,low energy group(35 cases).The operation time was statistically analysed.The postoperative stone shift rate and the postoperative stone-residual rate were also compared.
Results The operation time of the catheter drainage group[(35.4±5.5)min] was statistically lower than that of the routine lithotripsy group[(37.6±5.9)min](P<0.05).The postoperative stone shift rate in the catheter drainage group was statistically lower than that in the routine lithotripsy group:17.6% vs 34.6%(P<0.05).The postoperative stone shift rate in the low rate,low energy group was also statistically lower than that in the high rate,high energy group:11.4% vs 24.2%(P<0.05).
Conclusion Low rate,low energy of holmium laser combined with ureteral catheter is an effective method in ureteroscopic lithotripsy to treat upper ureter calculi,which reduces postoperative shift rate of stone and postoperative stone-residual rate,also shortens the operation time.
