经皮肾镜取石治疗肾下盏结石51例

摘要

Objective : To explore the effect of minimally invasive percutaneous nephrolithotomy (mPC-NL ) for kidney lower calycal calculi. Methods : Data of 51 cases with kidney lower calycal calculi treated by minimally invasive percutaneous nephrolithotomy (as the observation group) were reviewed . Compared the stone clearance of mPCNL group and 50 cases treated by extracorporeal shock-wave lithotripsy (ESWL) as the control group. Results : The complication rate of the observation group was 19 .6% , lower than that of the control group ,72 .0% (X2 = 27 .9 ,P＜0.01) ;the stone clearance of the observation group was 76 .5% , higher than that of the control group ,52 . 0%(X2=6.59 ,P＜0 .05) . Conclusion : The stone clearance of mPCNL is higher than that of ESWL ; the complication rate of mPCNL are lower than that of ESWL , which shall be prior to ESWL for kidney lower calycal calculi, diameter between 1 .0~2 .0cm .%目的:探讨应用经皮肾镜取石治疗肾下盏结石的临床疗效.方法:对51例肾下盏结石患者行经皮肾镜取石,并以同期收治的行体外冲击波碎石治疗的50例患者为对照组进行结石清除率比较.结果:观察组术后并发症发生率为19.6%,远低于对照组(72.0%,χ2=27.9,P<0.01).随访3个月后,观察组结石清除率为76.5%,明显高于对照组(52.0%,χ2=6.59,P<0.05).结论:对直径为1.0～2.0cm的肾下盏结石,经皮肾镜取石术结石清除率较体外冲击波碎石术高,并发症少,可作为优先选择的治疗方法.
