目的:探讨B超引导下肾上盏入路经皮肾镜取石术(PCNL)治疗肾铸型结石的安全性及临床疗效。方法:我们于2005年1月～2011年8月对27例肾铸型结石采用B超引导下肾上盏入路PCNL。建立经皮肾通道F24,经皮肾镜下EMS碎石清系统碎石。回顾性分析27例患者的手术时间、结石清除率、并发症等临床资料。结果:本组27例均成功建立经肾上盏通道,其中经第11肋间25例,经第12肋下2例。手术时间50～140min,平均85min。一期结石清除率85.2%(23/27)。胸腔积液1例(3.7%),输血1例(3.7%),无重要脏器损伤及其他严重并发症。结论:B超引导下肾上盏入路PCNL治疗铸型肾结石安全、有效。
Objective: To investigate the safety and clinical efficacy of percutaneous nephrolithotomy (PCNL) guided by B-ultrasonography in the treatment of renal calculi. Methods: From January 2005 to August 2011, 27 cases of renal calculus were treated with B ultrasound guided PCNL. The establishment of percutaneous renal access F24, percutaneous nephrolithotomy EMS lithotripsy clear gravel. A retrospective analysis of 27 patients with surgical time, stone clearance, complications and other clinical data. Results: Twenty-seven patients in this group were successfully established via the upper renal access, including 25 cases in the 11th intercostal space and 2 cases in the 12th rib. Surgery time 50 ~ 140min, an average of 85min. A stone clearance rate of 85.2% (23/27). Pleural effusion in 1 case (3.7%), transfusion in 1 case (3.7%), no important organ injury and other serious complications. Conclusion: It is safe and effective to use B-ultrasonography to lead PCNL in treating renal calculi.
