Preureteral Venacava: An Unusual Cause of Ureteral Obstruction

Abstract

Preureteral venacava is a rare congenital anomaly in which ureter passes behind the inferior venacava. It is due to abnormal persistence of right subcardical vein such that the ureter is trapped posterior to it. We present a case of 35 years old male who presented with right flank pain. Diagnosis was made by Computed Tomography (CT) urography which showed proximal ureteral dilatation with “J” shaped deformity. Open surgical repair resolved the symptoms.
