Distal urethral plate adhesions: New anatomical perspective in hypospadias

The distal urethral plate of all hypospadias patients is partially “folded” in the midline by epithelial adhesions of different depth and extent that may be easily dissoluted. In half of the patients (53%) the “folded” part of the plate continues proximally as a blind channel inside the urethral plate (type A channel). Opening of these structures together with the well-known urethral plate pits (type B channel) helps augment the width and the overall epithelized surface of the distal urethral plate.97Figure.
