Ureteral ectopia into seminal vesicle: embryology and clinical presentation.
The cause of ureteral ectopia in a single nonduplicated system is probably an abnormally high origin of the ureteral bud on the mesonephric duct. In the male patient with vague and unexplained lower urinary tract symptoms, extravesical ureteral ectopia must be considered, especially in prepubertal males with epididymitis and a solitary kidney. Physical examination, seminal vesiculography with delayed films, and voiding cystourethrogram should provide a diagnosis.
