A retrocaval ureter is a rare congenital cause of upper ureteric obstruction that results from entrapment of the upper ureter by the inferior vena cava (IVC) as it courses posterior to the cava. We report an interesting scenario of upper ureteric obstruction secondary to entrapment between twin segments of IVC. © 2012 Elsevier Inc.
