微创经皮肾穿刺取石术治疗输尿管上段嵌顿性结石(附71例报告)

Minimally Invasive Percutaneous Nephrolithotomy for Impacted Upper Ureteric Calculi (a Report of 71 Cases)

目的 评价微创经皮肾穿刺取石术治疗输尿管上段嵌顿性结石的疗效及并发症。 方法 采用微创经皮肾穿刺取石术治疗 71例输尿管上段嵌顿性结石患者 ,统计手术时间、结石清除率和并发症情况。 结果 平均手术时间为 4 5min ,一期结石清除率为 97.2 % (6 7 71) ,术后血红蛋白平均下降(0 .5 6± 0 .5 4 )g L ,无输血病例 ,术后 3d内体温超过 38.5℃ 4例。 结论 微创经皮肾穿刺取石术治疗输尿管上段嵌顿性结石安全有效 ,值得推广。

Objective To evaluate the effect and complications of minimally invasive percutaneous nephrolithotomy (mPCNL) for impacted upper ureteric calculi. Methods From May 2001 to February 2003, mPCNL was performed in 71 patients with impacted upper ureteric calculi. The time of the operation, stone-clear rate, and complications were evaluated. Results The average time of operation was 45 minutes. Stone-clear rate was 97.2%(69/71). Postoperative concentration of hemoglobin decreased by (0.56±0.54)g/L and blood transfusion was not needed. Four cases developed fever more than 38.5℃ within 3 days postoperatively. Conclusion Minimally invasive percutaneous nephrolithotomy is safe and effective in managing impacted upper ureteric calculi.
