微创经皮肾取石术处理开放手术后复发性肾结石的疗效分析

The Effect of Minimal Invasive Percutaneous Nephrolithotomy in the Treatment of Recurrent Nephrolithiasis After Open Nephrolithotomy

目的探讨微创经皮肾取石术(MPCNL)处理开放手术后复发性肾结石的疗效。方法选取有开放手术史的肾结石患者23例作为研究组,以及同期无开放手术史的肾结石患者23例作为对照组,均进行微创经皮肾取石术,比较两组的手术指标以及手术效果。结果研究组采用的手术通道情况与对照组相比,差异有统计学意义(P<0.05),显示研究组的手术难度明显增加;两组患者术中术后是否需要输血、手术时间、术后72小时内发热情况、结石清除率等比较,差异无统计学意义(P>0.05)。结论尽管开放手术增加了术中微创经皮肾处理的难度,但MPCNL仍是处理开放手术后复发性肾结石的安全、有效方法。

Objective To investigate the effect of minimally invasive percutaneous nephrolithotomy （MPCNL） for the recurrent nephrolithiasis after open nephrolithotomy. Methods 23 cases ofnephrolithiasis patients with history of open nephrolithotomy were selected as study group, and another 23 cases of nephrolithiasis patients without history of open nephrolithotomy at the same period were selected as control group. All cases received MPCNL. The operation indicators and therapeutic effects of two groups were compared. Results The nephrolithotomy channel had statistically significant difference between study group and control group （P 〈0.05）, indicating that the study group had significantly increased difficulty in surgery. No significant difference was found between study group and control group in the intraoperative or postoperative blood transfusion, surgical time, postoperative fever within 72 hours and calculi clearance rate （P 〉0.05）. Conclusions Although history of open nephrolithotomy increases the difficulty of surgery, MPCNL is still a safe and effective way for the treatment of recurrent nephrolithiasis after open nephrolithotomy.
