The patient simultaneously exhibited multiple congenital malformations of the homolateral urogenital system, such as absence of the left kidney, dysplasia and allotopia of the left seminal vesicle, absence of the left ureterostoma, separation between the left testis and the epididymis tail, and maldevelopment of the left testis. According to all clinical and laboratory evidence, the case represented a new syndrome, which we named Wuyang＇s syndrome. It involved a rare phenomenon in embryonic development; the dysplastic proximal vas precursor, having intruded into a common mesonephric duct and accidentally encroaching on the ureteric bud position, resulted in the absence or dysplasia of the homolateral urinary tract and ectopic invasion of the bladder by the homolateral seminal tract.展开更多
