title: Ureteropelvic junction obstruction caused by accessory renal vessels in association with preureteral vena cava and vena caval duplication.
abstract: An apparent ureteropelvic junction obstruction on the right side may herald an array of anomalous conditions for which the surgeon should be prepared. A case is presented in which ureteropelvic junction obstruction caused by accessory renal vessels was found in association with a preureteral vena cava and a vena caval duplication on the right side. The embryology of caval anomalies associated with preureteric vena cava is reviewed.
