Microsurgical one-stage repair of hypospadias with a rectangular transverse dorsal preputial vascularized skin flap.
A microsurgical technique for one-stage repair of hypospadias using a rectangular transverse dorsal preputial island skin flap is presented. The use of optical magnification, atraumatic technique, and microsurgical instruments allows a vascularized preputial skin flap to be raised and isolated on the dorsum of the penis and then rotated ventrally and tubulized into a neourethral channel. The meatus of the new urethral channel lies at the tip of the glans. Cover for the penis is simply obtained and does not require a longitudinal row of sutures. The need to remove the distal stenotic portion of the urethra and to correct any degree of chordee is outlined and emphasized. Good cosmetic and functional results demonstrate the efficacy of such a technique.
