Developmental anomalies of inferior vena cava are a rare cause of ureteral obstruction. We report a case that presented with right upper ureteral obstruction that radiologically simulated a retrocaval ureter. An aberrant vessel, which caused obstruction of the right ureter was identified at operation and surgical relief of ureteral obstruction was performed. Inferior venocavography was performed postoperatively and disclosed an unusual incomplete duplication of inferior vena cava. Our findings suggested that ureteral obstruction by incompletely duplicated anomaly of the inferior vena cava should be included in the differential diagnosis of extrinsic ureteral obstruction.
下腔静脉发育异常是输尿管梗阻的罕见原因。我们报告一例表现为右上输尿管梗阻的病例，其影像学表现类似腔静脉后输尿管。术中发现一条导致右输尿管梗阻的异常血管，并对输尿管梗阻进行了手术解除。术后进行了下腔静脉造影，发现下腔静脉存在不寻常的不完全重复畸形。我们的研究结果表明，下腔静脉不完全重复畸形导致的输尿管梗阻应列入外在性输尿管梗阻的鉴别诊断中。
