Abstract Neourethral diverticulum secondary to distal neourethral stenosis is not uncommon after proximal hypospadias repair. We describe a technique using the neo urethral diverticular roof and overlying skin as a composite flap to reconstruct the urethral stenosis distal to the diverticulum. The composite flap is advanced distally for reconstruction of the stenosed urethra either as a tube or as an onlay. Urethra at the diverticular bed is tubularized to reduce its caliber. This technique has yielded excellent results in three children. The tissue expansion caused by the obstructed urinary stream has been utilized to correct both neourethral diverticulum and stenosis.
