The rare duplications of the male urethra--only 210 cases are described till now--are found as many different variations. Only few of these malformations are symptomatic. The embryology is not always clear. Several classifications have been proposed, often too complicated or incomplete. We think, that our classification avoids these disadvantages. Each duplication is systematically classified in a morphological way according to the type of orifice (epispadiac, normotopic on the glans, hypospadiac, perineo-anal), without urinary transport (distal abortive types) or with urinary transport. The latter type can be complete (if a channel exists between bladder and an external meatus) or incomplete (if a channel exists between bladder and any point of the normal urethra or between the normal urethra and any accessory meatus). Four cases are reported and therapeutical aspects are discussed.
