目的观察微创经皮肾镜取石术(MPCNL)对开放手术后肾结石患者的临床疗效。方法对我院2009年1月—2013年6月收治的开放手术后肾结石患者56例进行MPCNL,并以同期初次行MPCNL患者50例作为对照,对两组患者手术情况、术后并发症和结石清除率进行比较。结果两组患者手术时间、术中出血量比较差异无统计学意义(P>0.05);住院时间观察组多于对照组,差异有统计学意义(P<0.05);观察组结石清除率88.79%,对照组90.64%,差异无统计学意义(P>0.05),两组未清除结石均为鹿角型或多发性结石;观察组并发症发生率16.07%,对照组14.00%,两组比较差异无统计学意义(P>0.05)。结论 MPCNL对开放手术后肾结石患者治疗与初次结石治疗并无明显区别,MPCNL是治疗肾结石的有效方法。
Objective To observe the clinical effect of minimally invasive percutaneous nephrolithotomy (MPCNL) in patients with kidney stones after open surgery. Methods Fifty-six patients with kidney stones after open surgery in our hospital from January 2009 to June 2013 were enrolled in this study. Fifty patients with MPCNL were enrolled in this study. The operative conditions, postoperative complications, Stone clearance rates were compared. Results There was no significant difference in operative time and intraoperative blood loss between the two groups (P> 0.05). There were significant differences in hospitalization time between the observation group and the control group (P <0.05). The stone clearance rate in the observation group was 88.79% , The control group 90.64%, the difference was not statistically significant (P> 0.05), the two groups of stones were open antlers or multiple stones; complication rate of the observation group was 16.07%, 14.00% in the control group, the difference between the two groups was no Statistical significance (P> 0.05). Conclusions There is no significant difference between MPCNL and primary calculus after open surgery for patients with kidney stones. MPCNL is an effective method to treat renal calculus.
