The purpose of this study was to evaluate the effects of treatment of curvature in Peyronie's disease with a relaxation incision and fascia lata grafting. Between 2000 and 2002, this technique was used for 12 patients with a 1-year history of plaque and curvature of more than 35 degrees. Penile degloving was performed with a circumferential incision. The tunica defect was closed with fascia lata grafting after a relaxation incision. For all patients, penile curvature was corrected and normal erections were achieved. No complication was observed in 9 to 24 months (mean, 10 months) of follow-up monitoring. The initial results suggested that tunica albuginea incision and fascia lata grafting could represent an alternative for the treatment of curvature in Peyronie's disease. Further studies are warranted.
