Retrocaval or circuncaval ureters are rare congenital anomaly, in which the ureter is located posterior to the inferior vena cava (IVC). Usually, patients present symptoms in the 3rd or 4th decade of life due to compression of the ureter by the IVC, with obstruction of the urinary flow and consequent hydronephrosis. Herein we report the case of a 62-year-old patient who underwent ultrasonography to investigate abdominal pain. The patient had bilateral renal lithiasis associated with urinary tract dilation with no obvious obstruction. Computed tomography of the abdomen demonstrated a retrocaval ureter without hydronephrosis.
腔静脉后输尿管或腔静脉周围输尿管是一种罕见的先天性异常，其中输尿管位于下腔静脉（IVC）后方。通常，患者在生命的第三个或第四个十年出现症状，原因是IVC压迫输尿管，导致尿流梗阻并继而引起肾积水。在此，我们报告一例62岁患者，该患者因腹痛接受超声检查。患者患有双侧肾结石并伴有尿路扩张，但无明显梗阻。腹部计算机断层扫描显示有一条腔静脉后输尿管，但没有肾积水。
