目的 研究输尿管镜碎石术治疗输尿管结石疗效的影响因素.方法 选择2009年6月～2013年3月在桐庐县中医院行输尿管镜碎石术治疗的输尿管结石患者350例,分析临床资料与碎石成功与否的关系.结果 350例患者输尿管镜一次性碎石成功279例（79.71％）,失败71例（20.29％）,成功组和失败组之间性别、年龄、病程、结石直径、结石嵌顿、碎石方法等因素差异有统计学意义（P＜0.05）.年龄、病程、结石嵌顿、碎石方法经多因素非条件logistic回归分析,是影响输尿管镜碎石效果的危险因素（P＜0.05）.结论 输尿管镜钬激光碎石的成功更高,年龄、病程、结石嵌顿与输尿管镜碎石术疗效密切相关.

英文摘要：

Objective To study the ureteroscopy lithotripsy for ureteral calculi efficacy factors. Methods From June 2009 to March 2013 in Tonglu county hospital ureteroscopy ureteral calculi were treated 350 cases,analysis of clinical data and gravel relationship success. Results A total of 350 patients,279 cases of successful ureteroscopy （79.71%）, failed 71 cases （20.29%）,between the success group and failure group sex,age,disease duration,stone diameter, im- pacted stones, gravel methods factors were significantly（P 〈 0.05）.Age, duration,impacted stones, gravel methods by multivariate unconditional logistic regression analysis ,was the impact risk factors for URSL effect（P 〈 0.05 ）. Conclu- sion The success of holmium laser lithotripsy higher age, duration of stone impaction with ureteroscopy efficacy are closely related.
