Urethral duplication is a rare anomaly, affecting mainly boys. The clinical presentation varies because of the different anatomical patterns of this abnormality. We report 4 cases of urethral duplication in children. An epispadiac duplication was present in 1 case, hypospadiac duplication in 1 case, Y-duplication in 1 case and a congenital prepubic sinus in the last case. The pre-operative probe was based on urethrocystography and fistulography. The surgical management included excision of the duplicated urethra in 3 cases. Transurethral incision of the intra-urethral septum was performed in the case of hypospadiac duplication. The characteristics of male urethral duplication are reviewed.
