目的探讨微创经皮肾镜取石术在开放手术后肾结石中疗效及安全性。方法选取2009年7月-2011年7月于本院采用传统经皮肾镜取石术进行治疗的28例开放手术后肾结石患者为对照组,同期采用微创经皮肾镜取石术进行治疗的28例患者为观察组,比较两组患者的结石清除率、手术时间、复发率、并发症发生率及手术前后的血清hs-CRP、肾功能指标。结果观察组结石清除率高于对照组,复发率及并发症发生率均低于对照组,术后7d的血清hs-CRP、Cr及BUN均低于对照组,GFR高于对照组,P均<0.05,而两组手术时间无显著性差异,P>0.05。结论微创经皮肾镜取石术在开放手术后肾结石中疗效及安全性均较佳。
Objective To investigate the efficacy and safety of minimally invasive percutaneous nephrolithotomy in the treatment of kidney stones after open surgery. Methods Twenty-eight patients with renal calculi treated by traditional percutaneous nephrolithotomy in our hospital from July 2009 to July 2011 were selected as the control group. The patients underwent minimally invasive percutaneous nephrolithotomy Twenty-eight patients were observed. The stone clearance rate, operation time, recurrence rate, complication rate and serum hs-CRP and renal function indexes before and after operation were compared between the two groups. Results The stone clearance rate in the observation group was higher than that in the control group, and the recurrence rate and complication rate were lower than those in the control group. The levels of hs-CRP, Cr and BUN in the 7th day after operation were lower than those in the control group <0.05, but no significant difference between the two groups operation time, P> 0.05. Conclusion The minimally invasive percutaneous nephrolithotomy is effective and safe in the treatment of kidney stones after open surgery.
