目的：：探讨经输尿管镜钬激光碎石术治疗输尿管结石患者的临床疗效。方法：临床纳入输尿管结石患者90例，根据碎石方案的不同分为研究组与对照组，研究组患者进行经输尿管镜钬激光碎石术( LL)，对照组患者进行体外冲击波碎石术( ESWL)。比较两组患者手术时间、术后3个月结石排净率等。结果：研究组患者治疗>1.0 cm与≤1.0 cm结石所需要的时间均短于对照组(P<0.05)；研究组术后3个月>1.0 cm结石排净率为91.67%，对照组患者为68.00%，差异有显著性(P<0.05)；研究组患者输尿管中下段术后3个月结石排净率为92.59%，对照组患者为72.00%，差异有显著性(P<0.05)。结论：体外冲击波碎石术适用于直径≤1.0 cm的输尿管上段结石，输尿管镜钬激光碎石术适用于直径>1.0 cm的输尿管中下段结石。

Objective: To study clinical efficacy of ureteroscopic holmium:YAG laser lithotripsy for patients with ureteral stones. Methods:90 ureteral stone patients were divided into study group and control group according to the different lithotripsy schemes. The study group received ureteroscopic holmium:YAG laser lithotripsy ( LL) , while the control group received extracorporeal shock wave lithotripsy ( ESWL) . The operation time and the stone clearance rate 3 months after the treatment of the two groups were compared. Results:For the stones>1. 0 cm and≤1. 0 cm, the operation time of study group was shorter than that of control group (P<0. 05). For the stones >1. 0 cm, the stone clearance rates 3 months after the treatment of study group and control group were 91. 67% and 68. 00%, respectively, and the difference was significant (P<0. 05). For the stones in middle and lower ureter, the stone clearance rates 3 months after the treatment of study group and control group were 92. 59% and 72. 00%, respectively, and the differ-ence was significant (P<0. 05). Conclusions:For the stones in the upper ureter and with a diameter of≤1. 0 cm, ESWL is superior to LL;however, for the stones in middle and lower ureter and with a diameter of >1. 0 cm, LL is more suitable.
