复杂肾结石在经皮肾术前1天行体外碎石的对比研究

摘要： 目的 探讨术前行体外冲击波碎石（ESWL）是否可以提高复杂性肾结石行经皮肾镜取石术（PCNL）的疗效。方法 选择复杂性肾结石病患160例，随机分为观察组和对照组，每组80例，对照组采取常规PCNL治疗，而观察组在常规PCNL术前1天行ESWL治疗，记录两组患者的手术时间、术中失血量、术后结石清除率、并发症、治疗费用和住院时间，对比两组疗效。结果 两组比较，手术时间、术中失血量、术后结石清除率、并发症、治疗费用和住院时间差异均有统计学意义（P <0.05），观察组较对照组全部具有明显优势。结论 对于复杂性肾结石，PCNL术前行ESWL治疗与常规PCNL比较，在残石率、手术时间、手术次数、并发症、治疗费用和住院时间方面均有明显优势，是一种经济安全而效果好的治疗方法。
Abstract: Objective To discuss whether preoperative extracorporeal shock wave lithotripsy (ESWL) could improve the efficacy of percutaneous nephrolithotomy (PCNL) for complicated renal calculi. Methods 160 cases of complicated renal calculi patients were divided into observation group (80) and control group (80) at random. Take conventional PCNL treatment for control group, and ESWL treatment one day before conventional PCNL treatment for observation group. Record the operation time, intraoperative blood loss, postoperative calculi clearance rate, complications, treatment costs, hospital stays of two groups of patients, then compare the curative effects between the two groups. Results Results are very different in the two groups, and the therapeutic effect of observation group is much better than control group (P < 0.05). Conclusions For complicated renal calculi, compared with conventional PCNL, in reducing the residual stone rate shorting the operation time, reducing the operation number, complications, treatment costs and the length of hospital stay, PCNL preoperative ESWL have obvious advantages. It is a kind of both economic and safe and effective treatment method.
