A new case of male Y-type urethral duplication and review of literature.

Urethral duplication is a rare congenital anomaly, affecting mainly boys. Generally, the duplication develops on the sagittal plane; the accessory urethra may run dorsally or ventrally to the orthotopic one. The embryology of this pathology is still controversial. In the English medical literature, approximately 175 cases have been reported. We report here a new case of urethral duplication type II A2 "Y" in a 14-year-old boy and review the current literature of this rare entity.
