Objective To investigate the methods, effects and advantages of percutaneous nephrostomy ( PCNL ) and mini-percutaneous nephrolithotomy ( mPCNL ) in the treatment of calculus pyonephrosis.Methods A retrospective analysis about clinical data of 18 patients with calculus pyonephrosis treated with standard percutaneous nephrolithotomy channel gravel and 22 patients treated with minimally invasive percutaneous nephrolithotomy stone lithotripsy.Data were collected from June 2006 to May 2010.Evaluated the treatment, clinical efficacy and its benefits and other information of these data.Results There was complete removal of stones in both groups, no significant difference was found in clearance rate of stone between the two groups( 81.3％ vs 89.0％ , P ＞ 0.05 ), renal function was normal after operation, no serious complications were occurred.Conclusion There was no significant difference in the stone free rate between the two methods.Both PCNL and mPCNL are safe and effective for the treatment of calculus pyonephrosis.%目的 探讨标准通道经皮肾镜与微创经皮肾镜碎石治疗结石性脓肾的方法、疗效及其优点.方法 回顾性分析2006年6月-2010年5月应用标准通道经皮肾镜碎石治疗18例及微创经皮肾镜碎石治疗22例结石性脓肾患者的临床资料,对其方法、临床疗效及其优点等资料进行评价.结果 2组结石均完全清除,结石取净率比较差异无统计学意义(81.3% vs 89.0%,P>0.05),术后肾功能正常,无严重并发症.结论 采用超声引导下标准通道经皮肾镜碎石与微创经皮肾镜碎石治疗结石性脓肾均安全有效.
