title: [A case of an incompletely duplicated ventral urethra].
abstract: A ventral incomplete duplicated urethra was found in a 20-year-old male. The accessory urethra lay ventral to and in parallel with the normal urethra. The external orifice of the accessory urethra was also ventral to the orifice of the normal urethra in the glans. On the other hand, the accessory urethra was closed near the bulbar region, and an abscess was found at the dead end. The accessory urethra, which was 9 cm long, was surgically removed. Histopathologically, the luminal surface was covered with a stratified squamous epithelium; and, smooth muscle and spongy tissue were observed around the accessory urethra. The classification of the duplicated urethra is discussed.
