Urethral duplication: cases of ventral and dorsal complete duplication and review of the literature.

Urethral duplication is a rare congenital anomaly, with multiple described anatomical variants. Duplications in the sagittal plane can be complete or partial, dorsal or ventral, and may be associated with other congenital urogenital anomalies. The anatomy of the duplication should be defined, and the functional urethra identified prior to any corrective surgical intervention. Correction aims to restore normal cosmesis, provide functional voiding and maintain continence. We describe two cases of urethral duplication in the sagittal plane, outline our approach to surgical correction, and review the literature.
