摘要: 目的:比较后腹腔镜输尿管切开取石术(RLU)、经肾镜取石术(mPCNL)、经输尿管镜取石术(URL)三种微创方法治疗嵌顿性输尿管上段结的临床疗效及安全性,探讨治疗嵌顿性输尿管上段结石的最佳手术方式。方法:229例嵌顿性输尿管上段结石患者229例患者随机分为3组,分别采用RLU(77例)、mPCNL(76例)和URL治疗(76例)。比较3组的治疗效果和并发症发生率。结果:RLU组和mPCNL组的手术成功率和结石取净率均明显高于URL组,分别为100% vs 100% vs 88.16%、100% vs 98.68% vs 82.09%(P <0.01)。RUL组的手术时间、住院时间均明显低于RLU组和mPCNL组,分别为(41.72±15.6)min vs(90.12±19.0)min vs (88.82±19.1)min、(3.70±1.9)d vs (8.65±1.6)d vs(8.76±2.1)d,P <0.01。mPCNL组的手术并发症发生率高于RLU组和URL组。结论:RLU、mPCNL及URL均可用于治疗嵌顿性输尿管上段结石,用何种方法应根据结石的位置、大小、存留时间及肾积水情况,遵循相对安全、有效、创伤小和经济实用的原则,并结合患者的个体差异,制定最佳方案。Abstract: Objective:To compare the efficacy of retroperitoneoscopic ureterolithotomy (RLU),minimally invasive percutaneous nephrolithotomy (mPCNL)and ureteroscopic lithotripsy (URL)for the treatment of impacted upper ureteral calculi,so as to explore the optimal treatment for impacted upper ureteral calculi.Method:A total of 229 cases of impacted upper ureteral calculi were randomized into 3 groups,receiving RLU (n=77),mPCNL (n=76)and URL (n=76),respectively.The therapeutic effect and the complication in the three groups were compared.Result:The success rate and stone free rate in Group RLU and Group mPCNL were significantly higher than Group URL (100% vs 100% vs 88.16%,100% vs 98.68% vs 82.09% respectively;P both <0.01),while the operation time and the length of stay in Group URL were significantly shorter than Group RLU and Group mPCNL (41.72±15.6) min vs (90.12±19.0) min vs (88.82±19.1) min,(3.70±1.9) d vs (8.65±1.6) d vs (8.76±2.1) d,P<0.01.Group mPCNL had higher complications.Conclusion:RLU,mPCNL and URL are applicable for the treatment of impacted upper ureteral calculi.An optimal therapeutic method should be determined according to the practical situation,including position and size of the stone,hydronephrosis,and other individual characters,following the principle of safety,utility,minimal invasiveness and economy.
