目的探讨经皮肾镜超声碎石取石术治疗输尿管上段结石的临床应用价值。方法回顾性分析2008年10月至2010年7月期间应用经皮肾超声碎石取石术治疗35例输尿管上段结石患者的临床资料,评估手术疗效及临床价值。结果 35例患者均一次穿刺成功,其中一期手术取净结石32例,其余3例因术后肾脏残留小结石,口服排石药物,3周后排出治愈。术后2～5 d复查腹部平片,结石基本取出,净石率为91.4%(32/35)。无大出血及输尿管穿孔、狭窄病例。结论经皮肾镜超声碎石取石术治疗输尿管上段结石临床疗效好,结石清除率高,术后患者不易发生碎石部位黏膜的出血,亦不会形成瘢痕导致输尿管狭窄,值得临床推广和应用。
Objective To investigate the clinical value of percutaneous nephrolithotomy lithotripsy in the treatment of upper ureteral calculi. Methods The clinical data of 35 patients with upper ureteral calculi treated with percutaneous nephrolithotomy lithotripsy from October 2008 to July 2010 were analyzed retrospectively to evaluate the curative effect and clinical value. Results All the 35 patients were successfully punctured. Among them, 32 cases were treated with net stones in one operation, and the remaining three patients were cured by small residual stones and oral row of stones after operation. 2 to 5 days after the operation, the abdominal plain film was taken and the stones were removed. The net stone rate was 91.4% (32/35). No major bleeding and ureter perforation, narrow cases. Conclusion Percutaneous nephrolithotomy lithotripsy for the treatment of upper ureteral calculi has good clinical curative effect, high rate of stone removal, postoperative patients are not prone to hemorrhage in the gravel site mucosa, and will not cause scar formation of ureteral stricture, worthy of clinical promotion and application.
