Y-type urethral duplication presented with perineal fistula in a boy.

Urethral duplication is a rare congenital anomaly of the lower urinary system and has varied presentation. According to the Effmann classification, type IIA2-Y urethral duplication is characterized by the duplicated urethra originating from the bladder neck and opening into either the rectum or the perineum. The accessory urethra is normal and functional and the normally positioned dorsal urethra is hypoplastic and stenotic in unusual form of Y-type duplication. We present a new case with unusual form of Y-type duplication and discuss its treatment.
