体外冲击波碎石术在双J管滞留结石形成中的应用

Application of Extracorporeal Shock Wave Lithotripsy in the Patients with Double Jureteral Stents Long-retention and Stone Adhesion

目的:评价体外冲击波碎石在处理双J管滞留结石形成中的应用价值。方法:运用慧康IV液电型体外冲击波碎石机对25例因双J管滞留结石形成拔管困难的患者进行体外冲击波碎石术后再拔管。结果:25例中,经体外冲击波碎石术后顺利拔出的21例(其中一次成功的12例,二次成功的9例),联合输尿管镜钬激光碎石后顺利拔出的4例。结论:体外冲击波碎石在处理双J管置留结石形成中具有方便、廉价、创伤小等优点,但成功率与双J管滞留的时间和结石程度等因素有关。

Objective To evaluate the application value of extracorporeal shock wave lithotripsy （ESWL） in the patients with double Jureteral stents long- retention and stone adhesion. Methods We withdrew the double Jureteral stents after doing ESWL by Hui-kang IV electro-hydraulic extracorporeal lithotrite for 25 patients. Results 12 patients were withdrawn stents successfully once, 9 patients were withdrawn twice. 4 patients were withdrawn by ureteroscopes. Conclusion ESWL is convenient, cheap and less invasive. The rate of success is relevant with the time of retention and the quality of stone.
