Between 1980 and 1986, 224 patients underwent one-stage hypospadias repair, of whom 100 were operated on using a modification of the Asopa technique. This technique, in which a vascularised preputial pedicle flap is rotated ventrally in order to reconstruct a neo-urethra as well as to cover the ventral skin defect, is described. The post-operative results are discussed. Fistula formation was the most common complication, but was easily correctable.
