Two Cases of Dorsal Urethral Duplication

Urethral duplication is a rare congenital anomaly. In addition to a normally urethra, there is an accessory urethra arising from the bladder or the proximal urethra which may open anywhere on the penis or even on the perineum. Many patients with this malformation are asymptomatic. Some patients may complain of intermittent discharge from the accessory urethra, incontinence, infection, double streams or stricture. The duplicated urethra may be complete or incomplete, may be located dorsal, ventral or in Y-type. The treatment of urethral duplication is individualized, depending on the type of malformation. We report two cases of dorsal urethral duplication discovered in two boys.
