1、输尿管镜钦激光碎石术后残留结石的因素分析【摘要】目的分析?尿管镜钦激光碎右术后残留结石的危险因素。方法收集接受输尿管钦激光碎石术治疗的输尿管结石患者361例，根据术后是否存在结石残留分为结石残留组（132例）和无结石残留组（229例）。对两组患者的临床特征、手术等情况进行单因素分析和Logistic多因素回归分析。结果361例患者结石残留率为36.6%；结石残留组患者的结石直径31cm的比例、结石位置在上屮段的比例、患侧肾功能受损的比例、术前有其他治疗史的比例明显高于无结石残留的患者（P〈0・05或0.01）,术后第2天尿量明显低于无结石残留患者
2、（P〈0.01）。输尿管钦激光碎石术后结石残留的危险因素为结石位置、患侧肾功能、术前治疗情况（P〈0・01）,保护因素为术后第1天尿量（P〈0.01）。结论结石位置、患侧肾功能、术前是否接受治疗是结石残留的危险因素，术后第1天尿量是结石残留的保护因素，故临床治疗此类结石时应重视这4个影响因素，以提高临床治疗效果。【关键词】输尿管镜钦激光碎右术；结右残留；危险因素中图分类号：R692.4文献标识码:AD0I:10.3969/j.issn.10031383.2017.01.016Analysisoffactorsofresidualstonesaft
