Despite the abundance of techniques for the repair of Hypospadias, its problems still persist and a satisfactory design to correct the penile curvature with the formation of neourethra from the native urethral tissue or genital or extragenital tissues, with minimal postoperative complications has yet to evolve.
Persisting with such an endeavor, a new technique for the repair of distal and midpenile hypospadias is described.
The study has been done in 70 cases over the past 11 years. The "Forked-Flap" repair is a single stage method for the repair of such Hypospadias with chordee. It takes advantage of the rich vascular communication at the corona and capitalizes on the established reliability of the meatal based flip-flap. The repair achieves straightening of the curvature of the penis by complete excision of chordee tissue from the ventral surface of the penis beneath the urethral plate. The urethra is reconstructed using the native plate with forked flap extensions and genital tissue relying on the concept of meatal based flaps. Water proofing by dartos tissue and reinforcement by Nesbit's prepucial tissue transfer completes the one stage procedure.
An analysis of 70 cases of this single stage technique of repair of penile hypospadias with chordee, operated at 3 to 5 years of age over the past 11 years is presented.
The Forked Flap gives comparable and replicable results; except for a urethrocutaneous fistula rate of 4% no other complications were observed.
尽管修复尿道下裂的技术众多,但其问题仍然存在,一种令人满意的设计,即利用天然尿道组织或生殖或生殖外组织形成新尿道来矫正阴茎弯曲,且术后并发症最少的方法尚未出现。
持续进行这样的努力,本文描述了一种修复阴茎远端和中段尿道下裂的新技术。
在过去11年中对70例患者进行了该研究。“叉状皮瓣”修复术是一种一期修复此类伴有阴茎下弯的尿道下裂的方法。它利用了冠状沟丰富的血管交通,并利用了基于尿道口的翻转皮瓣已确立的可靠性。通过从尿道板下方阴茎腹侧完全切除下弯组织,该修复术实现了阴茎弯曲的矫正。尿道利用天然尿道板并结合叉状皮瓣延伸和生殖组织进行重建,这依赖于基于尿道口皮瓣的概念。用肉膜组织进行防水处理,并用内斯比特(Nesbit)包皮组织转移进行加固,从而完成一期手术。
对过去11年中3至5岁接受手术的70例采用该一期技术修复伴有阴茎下弯的阴茎尿道下裂的病例进行了分析。
叉状皮瓣给出了可比且可重复的结果;除了4%的尿道皮肤瘘发生率外,未观察到其他并发症。
