摘要
目的:探讨输尿管硬镜下双频双脉冲激光治疗输尿管结石失败原因。方法:对25例输尿管硬镜下双频双脉冲激光治疗输尿管结石失败患者的临床资料进行分析。结果:25例患者术中19例结石回漂、移位进入肾盂,无法寻见结石;3例输尿管扭曲或狭窄,进镜困难而放弃;3例因输尿管开口异常,置镜失败而终止手术。结论:结石回漂入肾盂、输尿管扭曲或狭窄、输尿管开口异常是手术失败的主要原因。合适病例的选择,套石篮的应用,冲洗速度的调整,碎石时激光纤维的位置是手术成功的关键。
Objective：To assess the causes of the failure of frequency-doubled double-pulse laser for ureterosopy treatment in ureteralcalculi. Methods：To analyze the clinical data of 25 patients with ureteralcalculi failed in the frequency-doubled double-pulse laser for ureterosopic treatment. Results：The stones migrate to the renal pelvis and could not be found in 19 cases; 3 patients were stopped owing to the tortuosity or narrow of the ureters; 3 patients were halted due to abnormal opening of the ureters. Conclusions：The main causes of the failure are the stone migrations, tortuous or narrow ureters and abnormal opening of the ureters. The choice of suitable cases, usage of stone basket, appropriate flow rate and pressure of the fluid, the laser fiber position in ureterolithotripsy are important factors to elevate the success rate.
