目的:探讨腹腔镜经腹腔途径离断性肾盂成形术治疗肾盂输尿管连接部梗阻(UPJO)的技术特点、可操作性、并发症的防范处理等,充分评估该术式的临床适用性。方法:采用腹腔镜经腹腔途径离断性肾盂成形术治疗UPJO 23例,B超检查重度积水9例,中度12例,轻度1例,合并肾盂结石1例。结果:23例手术均获成功,手术时间90～150 min,术中失血20～100 ml,平均60 ml。术后住院时间5～7天,平均6天。术后无吻合口狭窄、漏尿及其他并发症发生。随访6～30个月,所有患者肾功能明显改善,肾积水消失或减轻。结论:针对UPJO,经腹腔途径离断性肾盂成形术有自身不可替代的特点和优点,仍是治疗UPJO有效的手术方式。 Objective: To evaluate the clinical characteristics of laparoscopic percutaneous pyeloplasty in the treatment of ureteropelvic junction obstruction (UPJO), and to evaluate the feasibility and feasibility of this procedure. Methods: Thirty-two cases of UPJO were treated by laparoscopic transepithelial pyeloplasty. There were 9 cases of severe hydrocephalus in B-mode ultrasound examination, 12 cases were moderate, 1 case was mild and 1 case was treated with pelvic pyeloplasty. Results: All the 23 surgeries were successful. The operation time was 90-150 min. The intraoperative blood loss was 20-100 ml, with an average of 60 ml. Postoperative hospital stay 5 to 7 days, an average of 6 days. No anastomotic stricture, leakage of urine and other complications occurred. Follow-up 6 to 30 months, all patients with renal function improved significantly, hydronephrosis disappeared or reduced. Conclusion: For UPJO, transperitoneal prolapse of pyeloplasty has its own irreplaceable features and advantages, is still an effective surgical treatment of UPJO.
