The authors report a rare congenital anomaly, retrocaval ureter (RCU) with carcinoma. The patient had recurrent pyelonephritis, hematuria and renal colic. Urography shows no function on right side. Abdominal ultrasound revealed marked right hydronephrosis. Antegrade ureterography through nephrostomy revealed a RCU. Helical C.T. confirmed the RCU and also revealed a defect in contrast medium in the upper ureter. We performed percutaneus antegrade nephro-ureteroscopy and found carcinoma of the retrocaval ureter. This may be the first case of tumor in the RCU. We did not find any other in the literature. (Fig. 3, Ref. 14.).
作者报告了一种罕见的先天性异常，即下腔静脉后输尿管（RCU）合并癌。患者有复发性肾盂肾炎、血尿和肾绞痛。尿路造影显示右侧无功能。腹部超声显示右侧明显肾积水。通过肾造瘘进行的顺行输尿管造影显示为下腔静脉后输尿管。螺旋CT证实了下腔静脉后输尿管，还显示上段输尿管造影剂充盈缺损。我们进行了经皮顺行肾输尿管镜检查，发现下腔静脉后输尿管癌。这可能是下腔静脉后输尿管肿瘤的首例病例。我们在文献中未发现其他相关病例。（图3，参考文献14。）
