目的探讨后腹腔镜输尿管切开取石术的技巧。方法应用后腹腔镜行输尿管上段切开取石7例,其中3例曾行ESWL失败,所有病例均经B超及IVP证实为输尿管上段结石。结果7例手术均取得成功,平均手术时间80 min,平均失血30 mL,7例均获得随访,随访时间为3-7个月,无并发症发生。结论后腹腔镜输尿管切开取石术损伤小、安全有效、恢复快,具有良好的临床应用前景。 Objective To investigate the technique of laparoscopic ureterolithotomy. Methods Laparoscopic ureteroscopic resection of the upper segment of the stone in 7 cases, of which 3 cases had failed ESWL, all cases were confirmed by B-ultrasound and IVP as the upper ureteral calculi. Results All the 7 surgeries were successful. The average operation time was 80 min and the mean blood loss was 30 mL. Seven patients were followed up for 3-7 months with no complication. Conclusions Retroperitoneal laparoscopic ureterolithotomy is less invasive, safe and effective, rapid recovery, and has good clinical application prospects.
