目的探讨输尿管镜下气压弹道碎石术( URSL)治疗复杂性输尿管结石疗效的影响因素。方法回顾性分析2009年6月—2013年7月铜陵市人民医院采用URSL治疗的132例复杂性输尿管结石患者的临床资料，按照术后1周复查输尿管B超或腹部X线平片显示无结石残留或结石<3 mm为成功、反之为失败的标准分组，其中手术成功111例为成功组、失败21例为失败组，对比分析两组患者治疗效果及影响疗效的因素。结果病程长短(>8周 vs≤8周)、结石嵌顿与否、结石大小(>1.2 cm vs≤1.2 cm)等指标两组患者比较差异有统计学意义(P值均<0.05)，是影响URSL治疗输尿管结石疗效的主要因素。结论病程长、结石嵌顿、结石较大等因素直接影响URSL的效果；采取有效的干预措施，可减少输尿管镜碎石术的失败比例。

Objective To investigate the influencing factors of ureteroscopic pneumatic ballistic lithotripsy ( URSL) in the treatment of complicated ureteral calculi. Methods From June 2009 to July 2013, clinical data of 132 cases with complicated ureteral calculi at Tongling People’s Hospital were retrospectively analyzed. Among them, the successful operation for 111 cases as group A and 21 failed cases as group B , test was used to investigate the effect of treatment and influencing factors of patients in two groups. Results When the course of disease was more than 8 weeks, incarceration stones, stone size had significant difference (all P values <0.05), which were dangerous influencing factors of URSL in the treatment of complicated ureteral calculi. Conclusions According to the factors of URSL effect, when the course of of disease is more than 8 weeks, incarceration and larger stones, effective measures should be taken to reduce the proportion of ureteroscopic lithotripsy failure.
