Abstract

Retrocaval ureter is a rare congenital anomaly that occurs is patients almost exclusively on the right side. The usual cause is the persistence of fetal posterior cardinal vein, then the ureter passes posterior to the vena cava and is deviated medially as the vena cava migrates medially to its normal position. This produces the typical S-shaped configuration of retrocaval ureter. Since 1983, when Hochstetter first described this condition. about 200 cases have been reported(8 cases in Korea).

Herein we will report on 2 cases with the brief review of literatures.
