目的探讨经皮肾镜取石术微通道组(MPCNL组)和标准通道组(PCNL组)治疗复杂性上尿路结石的可行性及安全性。方法回顾性分析南昌县人民医院2012年5月—2015年8月收治的复杂性上尿路结石患者140例的临床资料,随机分为MPCNL组和PCNL组,各70例。MPCNL组给予经皮肾镜取石术微通道取石治疗,PCNL组给予标准通道取石治疗,比较两组患者治疗效果。结果两组患者结石清除率、输血率比较,差异无统计学意义(P>0.05);MPCNL组术后高热发生率低于PCNL组,手术时间长于PCNL组,MPCNL组住院时间短于PCNL组,差异有统计学意义(P<0.05)。结论 MPCNL和PCNL治疗复杂性上尿路结石各有优势,两种方法结石清除率差异不明显,MPCNL术后发热率低、手术耗时长,但住院时间短。
Objective To investigate the feasibility and safety of percutaneous nephrolithotomy micro-channel group (MPCNL group) and standard channel group (PCNL group) in the treatment of complex upper urinary tract calculi. Methods The clinical data of 140 patients with complicated upper urinary tract calculi admitted from May 2012 to August 2015 in Nanchang People’s Hospital were retrospectively analyzed. They were randomly divided into MPCNL group and PCNL group, with 70 cases in each group. MPCNL group were given micro-channel lithotripsy by percutaneous nephrolithotomy, PCNL group was treated by standard channel stone, and the treatment effect was compared between the two groups. Results There was no significant difference in stone clearance rate and blood transfusion rate between the two groups (P> 0.05). The incidence of postoperative high fever in MPCNL group was lower than that in PCNL group and the operation time was longer than that in PCNL group. The length of stay in MPCNL group was shorter than that in PCNL group, The difference was statistically significant (P <0.05). Conclusion Both MPCNL and PCNL have the advantages in the treatment of complicated upper urinary tract calculi. There is no obvious difference between the two methods in the stone clearance rate. The postoperative MPCNL rate is low, the operation time is long, but the hospitalization time is short.
