To evaluate the technique and the clinical efficacy of Retroperitoneoscopic dismembered pyeloplasty in children.
Retroperitoneoscopic dismembered pyeloplasty was performed on 17 patients of pediatric ureteropelvic junction (UPJ) obstruction, age ranging from 3 - 10 years. All patients had radiographic evidence of obstruction with signs, symptoms or deterioration of renal function.
All of the 17 operations were performed successfully, and no serious complications occurred during and after the operations. Average operating time was 4.3 hours, which decreased with surgeon experience. Average blood loss was 38 ml, mean postoperative stay was 4.6 d. Only one case had postoperative urine leakage. With a mean follow-up of 14 months, all patients were free of obstruction on follow-up radiographic imaging.
Retroperitoneoscopic dismembered pyeloplasty is a safe, effective and minimally invasive procedure for treatment of UPJ obstruction in children, and it can be used as an alternative to open surgery.
评估后腹腔镜离断性肾盂成形术治疗儿童肾盂输尿管连接部（UPJ）梗阻的技术及临床疗效。
对17例年龄在3至10岁的小儿肾盂输尿管连接部梗阻患者行后腹腔镜离断性肾盂成形术。所有患者均有梗阻的影像学证据，并伴有体征、症状或肾功能恶化。
17例手术均成功完成，术中及术后均未发生严重并发症。平均手术时间为4.3小时，随着术者经验增加手术时间缩短。平均失血量为38毫升，术后平均住院时间为4.6天。仅1例患者术后出现尿漏。平均随访14个月，所有患者随访影像学检查均无梗阻。
后腹腔镜离断性肾盂成形术是治疗儿童肾盂输尿管连接部梗阻的一种安全、有效且微创的手术方法，可作为开放手术的替代方法。
