Abstract
Summary The onlay island flap urethroplasty was originally used to repair anterior hypospadias without chordee and was later used to repair penile hypospadias with a well developed urethral plate exhibiting little or no chordee after release of skin tethering. It is possible to treat all cases of penile hypospadias even with severe chordee by releasing the chordee without dividing the urethral plate and by reconstructing the urethra with an onlay island flap.
