【摘要】目的：评价肾下盏解剖结构对输尿管软镜结合钬激光治疗肾下盏结石

的影响。方法：对60例肾下盏结石患者顺行尿路造影片上肾盂输尿管与肾下盏漏

斗部夹角、肾下盏漏斗部长度及最窄宽度和输尿管软镜下钬激光的结石治疗效果

间关系进行分析。结果：结石治愈患者的肾盂输尿管与肾下盏漏斗部夹角显著大

于未治愈患者（P=0.009），而肾下盏漏斗长度和漏斗部宽度在两组患者间均无统

计学差异。若患者按肾盂输尿管与肾下盏漏斗部夹角进行分组，则夹角90º的患

者治愈率为92.3%，夹角为30～90º的患者治愈率为73.2%，夹角30º的患者治愈

率为0%。Logistic回归分析表明肾盂输尿管与肾下盏漏斗部夹角是结石治愈与

否的决定因子（OddsRatio1.124，p0.001）。结论：肾盂输尿管与肾下盏漏斗

部夹角对输尿管软镜治疗肾下盏结石有影响。
