多通道微创经皮肾镜结合钬激光治疗复杂性肾结石的临床研究

目的 探讨多通道微创经皮肾镜结合钬激光治疗复杂性肾结石的临床疗效.方法 将86例复杂性肾结石患者分为两组,研究组(46例)采用多通道微创经皮肾镜结合钬激光碎石术,对照组(40例)行单通道微创经皮肾镜结合体外冲击波碎石术治疗.比较两组碎石取出时间、结石清除率、术后血红蛋白下降率、术中输血率、术后住院时间及并发症发生率.结果 研究组的碎石取出时间为(102±23)min,对照组为(121±28)min,两组比较差异无统计学意义(P＞0.05).研究组术后血红蛋白下降率为6.5%(3/46)、术中输血率为17.4%(8/46)、结石清除率为82.6%(38/46)、术后住院时间为(5.6±1.7)d,对照组分别为12.5%(5/40)、22.5%(9/40)、72.5%(29/40)、(7.4±1.8)d,两组比较差异均有统计学意义(P＜0.05).结论 多通道微创经皮肾镜结合钬激光治疗复杂性肾结石手术时间短、术中出血少、结石清除率高,且并发症相对较少,值得临床推广应用.

Abstract：

Objective To investigate the effect of multi-channel minimally invasive percutaneous nephrolithotomy in combination with Yag laser in complex renal calculi operation. Methods Eighty six complex renal calculi patients were divided into two groups, study group (46 cases) was treated with multi-channel minimally invasive percutaneous nephrolithotomy combined with Yag laser, control group was treated with single-channel minimally invasive percutaneous nephrolithotomy combinated with extracorporeal shock wave treatment. Comparison of gravel removed time, stone clearance rate,postoperative hemoglobin decreasing rate, blood transfusion rate of surgery,length of stay time and operative complications were done between the two groups, the results were analysed statistically. Result The gravel removed time was (102±23) min in study group, and ( 121 ± 28) min in control group, there was no significant difference between the two groups(P ＞ 0.05 ). In study group, postoperative hemoglobin decreasing rate was 6.5%(3/46), blood transfusion rate of surgery was 17.4% (8/46), stone clearance rate was 82.6%( 38/46 ), length of stay time was (5.6 ± 1.7) d,while those in control group was 12.5%(5/40),22.5%(9/40),72.5%(29/40), (7.4 ± 1.8) d,respectively. There was statistical significance between the two groups(P＜ 0.05 ). Conclusion Multi-channel minimally invasive percutaneous nephrolithotomy in combination with Yag laser in the treatment of complex renal calculi has the shorter operation time, less blood loss,less complications and higher stone clearance rate, and is worthy of promotion.
