Abstract

We present the case of ureteral triplication with vesicoureteral reflux into the lowest and middle pole in a 5-year-old girl. Magnetic resonance (MR) nephrography depicted loss of function of the lowest pole, which could not be assessed through MAG3 renal scan. Morphologic analyses revealed organ structure and vascular anatomy in superior quality. A laparoscopic partial nephroureterectomy of the lower pole was performed. Intraoperative findings correlated exactly with morphologic data obtained through MR nephrography. Dynamic MR nephrography should be considered as diagnostic tool of choice for selected kidney anomalies before surgery.

摘要

我们报告了一例 5 岁女孩输尿管三重畸形伴最低和中间极的膀胱输尿管反流。磁共振尿路成像（MR 尿路造影）显示最低极功能丧失，MAG3 肾扫描无法评估。形态学分析显示上极的器官结构和血管解剖质量较高。行腹腔镜下下极部分肾输尿管切除术。术中所见与 MR 尿路造影获得的形态学数据完全吻合。动态 MR 尿路造影应作为术前选择的特定肾脏异常的首选诊断工具。
