Abstract

Urethral duplication is a rare congenital anomaly that can present in various clinical forms according to the plane and extent of duplication. Although some are associated with abnormalities of the external genitalia, others present as mild condition which is incidentally found. Nine cases of complete and incomplete types of urethral duplication have been reported in the Korean literature. We report the clinical presentation and management of four cases of various types of urethral duplication in boys
