MAGPI 术于1986年在我国首次开展以来,为无阴茎下弯或有轻度阴茎下弯的冠状沟型尿道下裂的患儿提供了一个较好的手术方法。可是在冠状沟型尿道下裂中仍有部分伴有中度或以上的阴茎下弯畸形,仅用 MAGPI 术则难干解决阴茎下弯的问题。而用尿道延伸术又易造成尿道口的狭窄或尿道远端的缺血坏死,甚至尿道回缩等。因此,我们将尿道延伸术加以改进,并与 MAGPI 术联合应用于10例有中度阴茎下弯的冠状沟型尿道下裂,均获成功。 MAGPI surgery in 1986 in our country since the first since, for no penile or mild penile coronal hypospadias children provide a better surgical method. However, in the coronary sulcus hypospadias still some with moderate or more penile deformity, only MAGPI surgery is difficult to solve the problem of penile curvature. Urethral extension and easily lead to urethral stricture or distal necrosis of the urethra, and even urethral retraction. Therefore, we have to improve the urethral extension and combined with MAGPI surgery applied to 10 cases of subdural coronal hypospadias, were successful.
