title: The ectopic ureter in men.
abstract: The ectopic ureter is less common in male than in female patients. It usually terminates proximally to the external sphincter in the seminal vesicle or vas deferens, and usually involves a nonduplicated drainage system of a dysplastic kidney. Men characteristically present with lower tract symptoms, often epididymitis, a cystic or boggy periprostatic mass on rectal examination and ipsilateral nonvisualization on excretory urography. The embryology, pathogenesis, diagnosis and treatment of this condition are discussed, and 4 illustrative cases are presented.
