目的:评估双频双脉冲激光联合钬激光碎石术治疗复杂性输尿管结石的疗效。方法:采用输尿管镜双频双脉冲激光联合钬激光治疗复杂性输尿管结石39例,其中输尿管结石合并息肉30例,输尿管结石合并输尿管狭窄9例。先应用钬激光切除输尿管结石下方的息肉或切开结石下方的狭窄处,再应用双频双脉冲激光进行碎石。结果:一次手术碎石成功率为92.3%,2例发生结石上漂,1例输尿管穿孔转开放手术。平均手术时间39m in,平均激光工作时间25m in,术后平均住院3.2天。结论:应用双频双脉冲激光联合钬激光碎石术治疗伴有息肉或狭窄的复杂性输尿管结石是安全、有效的。
Objective: To evaluate the efficacy of dual-frequency and double-pulsed laser combined with holmium laser lithotripsy in the treatment of complicated ureteral calculi. Methods: 39 cases of complex ureteral calculi were treated with ureteroscope dual-frequency and double-pulsed laser combined with holmium laser, including 30 cases of ureteral calculi complicated with polyps, 9 cases of ureteral calculi combined with ureteral stricture. The first application of holmium laser excision of the polyps below the ureteral stones or incision below the stenosis, and then double-frequency dual-pulse laser lithotripsy. Results: The success rate of one operation was 92.3%. Two cases had stone floating and one case had perforation to open surgery. The average operation time was 39m in, the average laser working time was 25m in, and the average postoperative hospital stay was 3.2 days. CONCLUSIONS: The use of dual-frequency, double-pulsed laser in combination with holmium laser lithotripsy for the treatment of complicated ureteral calculi with polyps or stenosis is safe and effective.
