Herein we present a rare ureteric duplication anomaly; blind ending bifid ureter with calculi which is asymptomatic unless complicated by infection, reflux, calculi or malignancy. The diagnosis is often missed at intravenous urography (IVU) and US because the ipsilateral ureter and kidney are grossly normal. In this case the diagnosis was established with ultrasound (US) and mainly with multidetector computerized tomography (MDCT) imaging using multiplanar reformats and 3-D reconstructions which were unique to this case. MDCT scans not only revealed the exact diagnosis and anatomic relationships but also ruled out other pathologies included in the differential diagnosis as well, such as ureter and bladder diverticula.
在此，我们呈现一例罕见的输尿管重复畸形；盲端双输尿管伴结石，若无感染、反流、结石或恶性肿瘤等并发症，则无症状。静脉肾盂造影（IVU）和超声检查时常常漏诊，因为同侧输尿管和肾脏大体正常。在本病例中，通过超声（US），主要是利用多平面重建和三维重建的多排螺旋计算机断层扫描（MDCT）成像确诊，此为该病例所特有。MDCT扫描不仅明确了确切诊断及解剖关系，还排除了鉴别诊断中包含的其他病变，如输尿管和膀胱憩室。
