title: Onlay island flap urethroplasty for severe hypospadias: a variant of the technique.
abstract: A variant of the onlay island flap urethroplasty in severe hypospadias repair is described. The principles of the technique include mobilization of the urethral plate without dividing it, release of chordee, creation of a pedicle island flap on the dorsal penile skin with redundant vascularized tissue that is transposed to the ventral side of the penis by a buttonhole maneuver, and onlay of the flap to the mobilized urethral plate, covering all suture lines with a wide pedicle of flap. During the last 3 years this operation was performed in 92 patients 12 months to 19 years old with severe hypospadias. The complication rate was 5%.
