目的:探讨阴茎纵行腹外侧肉膜瓣在远端尿道下裂Ⅰ期修复术中的应用价值。方法:对55例阴茎远端型尿道下裂患者先行尿道板纵切卷管尿道成形术(TIP)修复尿道,然后采用阴茎纵行腹外侧阴茎肉膜瓣对修复新尿道进行覆盖。结果:55例患者均获得类似包皮环切术后样外观,尿道外口开口于阴茎头顶端呈裂隙状;仅4例(7.3%)于冠状沟处发生尿道瘘。结论:在远端尿道下裂Ⅰ期修复术中,以阴茎纵行腹外侧肉膜瓣对新尿道加以覆盖,能有效降低尿道瘘的发生率,且修复后阴茎获得类似包皮环切术后样外观。
Objective: To investigate the value of penile lateral venous flap in the repair of distal hypospadias. Methods: 55 urethral distal hypospadias patients underwent urethroplasty and urethroplasty (TIP) to repair the urethra, and then covered the urethra with penile lateral penile flap. RESULTS: All 55 patients had a similar appearance after circumcision. The opening of the urethra was fissured at the tip of the glans penis. Only 4 cases (7.3%) had urethral fistula at the coronary sulcus. Conclusion: During the first stage repair of distal hypospadias, the new urethra is covered with the penile lateral ventromedial membrane flap, which can effectively reduce the incidence of urethral fistula. After the repair, the penis is similar to the circumcision Exterior.
