We report 7 cases of severe Peyronie's disease treated with a modified surgical technique of the one described in 1989. This second version consists of making only one I-shaped incision on the dorsal face of the penis, in order to relax and create a defect in the tunica albuginea, which is then covered with a patch of human lyophilized dura mater. The plastic and sexual results were identical to the ones described previously, but the operative time was shortened. This type of surgery is indicated to correct severe angulation and shortening of the penis in men with normal sexual lives.
