From January 1983 to December 1985, 14 procedures were performed in which a free graft of skin from either the foreskin or elsewhere was substituted for the flipped flap in the repair of hypospadias. This obviates the problem of thin skin below the urethral meatus, since a flipped flap in such a case will result in devascularization of the flap. Moderate chordee was not necessarily a contraindication to the use of this procedure, provided the chordee could be corrected without moving the meatus proximally. Cosmetic and functional results have been good, and there was only 1 urethral fistula. Nevertheless, because of the need for a scrotal flap of fat to prevent fistula formation and to ensure vascularization of the graft, and because of the availability of a vascularized flap from the foreskin in most cases, the free graft patch procedure is best reserved for cases in which the foreskin is either absent or deficient.
1983年1月至1985年12月期间，共进行了14例手术，在尿道下裂修复中，采用来自包皮或其他部位的游离皮片替代翻转皮瓣。这避免了尿道口下方皮肤过薄的问题，因为在这种情况下使用翻转皮瓣会导致皮瓣缺血。只要阴茎弯曲能够在不将尿道口向近端移位的情况下得到矫正，中度阴茎弯曲不一定是该手术的禁忌证。美容和功能效果良好，仅出现1例尿道瘘。然而，由于需要阴囊脂肪瓣来防止瘘管形成并确保移植皮片的血管化，且在大多数情况下可获得来自包皮的带血管蒂皮瓣，游离移植补片手术最好保留用于包皮缺失或不足的病例。
