目的 探讨微创经皮肾镜取石术(MPCNL)治疗肾盂和输尿管上段嵌顿结石的疗效.方法 84例肾盂和输尿管上段嵌顿结石患者随机均分为两组,观察组采用MPCNL治疗,对照组采用输尿管镜取石术治疗.比较两组手术时间、碎石成功率、住院时间、住院费用及并发症发生情况.结果 与对照组比较,观察组手术时间短,住院时间及住院费用较高,碎石成功率也较高(P＜0.01).两组术后并发症发生率无统计学差异(P＞0.05).结论 MPCNL治疗肾盂和输尿管上段嵌顿结石能够提高碎石成功率,缩短手术时间,并发症少.“,”Objective To investigate the efficacy of minimally invasive percutaneous nephrolithotomy(MPCNL) in the treatment of renal and upper ureteral incarcerated stone.Methods A total of 84 cases with renal and upper ureteral incarcerated stone was equally divided into two groups.Group A was treated with MPCNL and group B was treated with ureteroscopic lithotomy.The operative time,success rate of lithotripsy,hospital stay,hospitalization cost and complications were compared between two groups.Results Compared to group B,group A had shorter operative time and higher success rate of lithotripsy,longer hospital stay and more medical cost(P＜0.01).The incidence rates of complications of two groups were similar (P＞0.05).Conclusion Treating the renal and upper ureteral incarcerated stone with MPCNL can improve the success rate of lithotripsy,shorten the operation time and reduce complications.
