Ureteropelvic junction obstruction caused by accessory renal vessels in association with preureteral vena cava and vena caval duplication.
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.
