Computerized tomography (CT), intravenous pyelography (IVP), and ultrasound characteristics of nonobstructive right circumcaval ureter associated with double inferior vena cava in an adult is presented. The CT appearance of the retrocaval segment of the circumcaval ureter which was detected as a "thin, long line" suggests it might be a useful sign in the incidental diagnosis of the anomaly even on noncontrast-enhanced abdominal CT examination. Because of the unique IVP appearance of circumcaval ureter in this case, a new classification is presented.
本文介绍了一名成人非梗阻性右侧腔静脉后输尿管合并双下腔静脉的计算机断层扫描（CT）、静脉肾盂造影（IVP）及超声特征。腔静脉后输尿管腔静脉后段在CT上表现为“细长线”，提示即使在非增强腹部CT检查中，这也可能是该异常偶然诊断的有用征象。由于本例中腔静脉后输尿管独特的IVP表现，提出了一种新的分类方法。
