微通道与标准通道经皮肾镜碎石术处理肾铸型结石疗效的比较

摘要

Objective: To compare the outcome of mini-tract vs standard-tract percutaneous nephrolithotomy (PCNL) in staghorn calculi.Methods: Between May 2009 and May 2011, 122 patients with renal staghorn calculi were treated by PCNL. Fifty-six patients underwent mini-PCNL and the others underwent standard-PCNL. The therapeutic effect and complication of the 2 groups were compared. Results: The two groups had comparable demographic conditions. Although the operation time was significantly longer in mini-PCNL group [(126±24.5) min vs (98+18.9) min], there was no striking difference in hospital stay [(5.7±1.3) d vs (5.3±l.l) d], hemoglobin drop [(9.5±3.2) g/L vs (10.5±3.3) g/L], stone-free state before charge (91.1% vs 89.4%) and complications. Conclusion: The efficacy and safety of mini-PCNL and standard-PCNL are not significantly different.%目的:探讨微通道和标准通道经皮肾镜碎石术(PCNL)在治疗肾铸型结石方面的临床效果.方法:收集肾铸型结石且进行了PCNL治疗的122例患者临床资料进行回顾性分析,根据不同工作通道分为微通道PCNL组和标准通道PCNL组,比较两组间术中术后情况包括手术时间、术后结石清除率、并发症等,并进行统计分析.结果:微通道PCNL组56例,标准通道组66例,微通道PCNL组手术时间长于标准通道PCNL组[(126±24.5) min vs (98±18.9) min],两组间在住院天数[(5.7±1.3)d vs(5.3±1.1)d]、出院前结石清除率(91.1％ vs 89.4％)、血红蛋白下降值[(9.5±3.2)g/L vs (10.5±3.3) g/L]及手术相关并发症等方面差别并无统计学意义(p＞0.05).结论:微通道与标准通道PCNL在处理肾铸型结石的临床疗效与安全性方面无明显差别.
