目的探讨经皮肾微造瘘取石术(PCNL)结合体外震波碎石(ESWL)治疗复杂性肾结石的临床效果。方法对54例复杂性肾结石患者采用经皮肾微造瘘取石术,结合一次或多次ESWL治疗。结果经皮肾微造瘘取石术结合一次ESWL治疗后结石清除率为74%,二次ESWL治疗后结石清除率88.8%,三次ESWL治疗后结石清除率为92.5%。结论经皮肾微造瘘取石术结合一次或多次ESWL治疗复杂性肾结石安全、有效值得临床推广应用。
Objective To investigate the clinical effect of percutaneous nephrostomy (PCNL) combined with extracorporeal shock wave lithotripsy (ESWL) in the treatment of complex renal calculus. Methods Fifty-four patients with complicated renal calculi underwent percutaneous nephrostomy combined with one or more ESWL treatments. Results The stone clearance rate after percutaneous nephrostomy combined with ESWL treatment was 74%. The stone clearance rate after secondary ESWL treatment was 88.8%. The stone clearance rate after three ESWL treatments was 92.5%. Conclusion Percutaneous nephrostomy combined with one or more ESWL in the treatment of complex renal stones is effective and worthy of clinical application.
