Diphallus in an adult: microsurgical treatment--case report.

A case of true, complete diphallus in an adult, associated with multiple malformations, is presented. The left urethra was perineal hypospadic; the right posterior urethra was small in caliber; and the right testis and spermatic cord were absent. The chordee was released; the right penis was resected and transferred to elongate the left one; and the urethra was reconstructed with a radial forearm free flap. Follow-up of more than 6 years shows that the patient has a good functional and cosmetic result.
