摘　　要：目的 :评价钬激光碎石术 (LL)治疗输尿管上段结石的疗效。方法 :回顾性分析应用OmnipulseTM钬激光机经输尿管镜治疗 137例输尿管上段结石患者的资料。结果 :12 2例输尿管上段结石原位 1次碎石成功 ,10例结石被冲入肾盂 (有 2例继在肾盂内行钬激光碎石获成功 ) ;2例在处理并发的输尿管息肉时发生输尿管穿孔改行开放手术 ,2例因输尿管下段特别狭窄经输尿管扩张 1周后再行内腔镜治疗成功 ,1例碎石过程中出现大量絮状脓液改行手术摘除患肾。单次LL成功率为 90 .5 % (12 4 / 137)。术后结石排净时间平均 2 .8周 ,术后无明显血尿、梗阻性脓肾等并发症发生。结论 :合理选择病例、提高操作技巧 ,LL可作为输尿管上段结石的首选方法。Objective:To evaluate the clinical effects of Ho:YAG laser lithotripsy(LL) on the treatment of upper-ureter caculi.Method:The clinic data of 137 cases of upper-ureter caculi via ureteroscope with OMNIPULSETM Ho:YAG lithotriptor were retrospectively analyzed.Result:The calculi of 122 cases were fragmented in situ after a single session. 2 of the 10 cases flushed to the pelvis were fragmented successfully in the pelvis. Ureter perforation occurred in 2 cases and 3 cases failed in the procedure. The successful caculi fragmentation rate of one lithotripsy was 90.51%(124/137). The mean expectoration time of caculi-free was 2.8 weeks.Conclusion:LL is one of the best choices for upper ureter caculi when proper indications exist and good techniques under ureteropyeloscope are provided.
