Interiliac Ureter: A Rare Venous Anomaly Causing Hydronephrosis.

Most of the developmental anomalies of inferior vena cava are asymptomatic. The retrocaval and retroiliac ureter, however, commonly present with symptoms due to ureteric obstruction. We present interesting computed tomography images of a 30-year-old male who was symptomatic for right upper ureteric obstruction and the ureter was coursing between the 2 common iliac veins that were uniting abnormally high at the level of right renal hilum with absence of infrarenal inferior vena cava.
