Embryologic preputial sinus remnant mimicking urethral duplication.

Urethral duplications are rare congenital anomalies. Approximately 200 cases of urethral duplications have been reported in literature. We present a seven-year-old-boy with an embryologic preputial sinus remnant which was mimicking urethral duplication. The clinical presentations and embryology of the urethral duplication and preputial sinus are discussed.
