目的探索后腹腔镜下离断式肾盂输尿管成形术治疗小儿肾盂输尿管连接部梗阻。方法选取肾积水患儿18例,左侧15例,右侧3例。B超放射检查均提示梗阻位于肾盂输尿管连接处。采用后腹腔镜下离断式肾盂成形术。结果 18例患儿手术均成功,无中转开放。手术时间192~345分钟,平均224分钟。术中平均出血量约8 ml。术后B超随访12~24个月,平均18个月,肾盂液暗区明显减小。结论后腹腔镜下肾盂成形术是治疗小儿肾盂输尿管连接部梗阻肾积水的可靠方法。术后肾盂形态恢复良好,肾积水明显消退。
Objective To investigate the treatment of pediatric ureteropelvic junction obstruction by retroperitoneal laparoscopic ureteropelvic pyeloplasty. Methods 18 cases of children with hydronephrosis, left in 15 cases, right in 3 cases. B ultrasound examination showed obstruction in the ureteropelvic junction. Retroperitoneal laparoscopic pyeloplasty. Results 18 cases of children were successful surgery, no transit open. Surgery time 192 ~ 345 minutes, an average of 224 minutes. Intraoperative blood loss of about 8 ml. B-postoperative follow-up of 12 to 24 months, an average of 18 months, the dark area of the pelvis fluid was significantly reduced. Conclusions Laparoscopic pyeloplasty is a reliable method for the treatment of hydronephrosis in pediatric ureteropelvic junction obstruction. Postoperative pyelography recovered well, hydronephrosis subsided.
