目的观察经尿道输尿管镜钬激光碎石术治疗输尿管结石的临床疗效。方法 2009年1月至2012年3月东营市第二人民医院采用输尿管镜钬激光碎石术治疗收治的186例输尿管结石患者,分析其一次性碎石成功率、并发症发生率、手术及住院时间。结果 179例患者顺利完成手术,一次性碎石成功率为96.2%,其中输尿管上段结石一次性碎石成功率为81.5%(22/27),输尿管中段结石一次性碎石成功率为96.8%(61/63),输尿管下段结石一次性碎石成功率为100%(96/96)。术后并发症发生率为7.3%(13/179),手术时间(57±15)min,住院时间(5.7±1.3)d。术后179例碎石成功者4周结石排净率为95.5%(171/179),8周结石排净率为100%。结论经尿道输尿管镜钬激光碎石术治疗输尿管结石的临床疗效显著,损伤小,安全性高,是目前腔道碎石中理想的方法之一。
Objective To observe the clinical efficacy of transurethral ureteroscopic holmium laser lithotripsy in the treatment of ureteral calculi. METHODS: From January 2009 to March 2012, 186 patients with ureteral calculi treated by ureteroscopic holmium laser lithotripsy were treated in Dongying Second People’s Hospital. The success rate of one-off lithotripsy, the incidence of complications, operation and hospitalization time. Results A total of 179 patients successfully completed the operation. The success rate of one-time lithotripsy was 96.2%. The success rate of disposable ureteral stones was 81.5% (22/27), and the success rate of disposable ureteral stones was 96.8% 61/63). The success rate of disposable ureteral stones was 100% (96/96). The incidence of postoperative complications was 7.3% (13/179), operation time (57 ± 15) min, and hospitalization time (5.7 ± 1.3) days. 179 cases of gravel after 4 weeks of stones were cleared rate was 95.5% (171/179), 8 weeks stone discharge rate was 100%. Conclusions Transurethral ureteroscopic holmium laser lithotripsy for the treatment of ureteral calculi has obvious curative effect, small injury and high safety. It is one of the ideal methods in the present study.
