Koff's procedure in the treatment of distal hypospadias consist in a large mobilization of the distal urethra. The association to a transglandular funelization and minimal urethroplasty is useful for the treatment in the majority of patients with distal hypospadias. In the last two years 34 patients with distal types of hypospadias were operated with a Koff's modified procedure. The technique consists in a urethral advancement without glanduloplasty and distal cutaneous tubulization. The primitive meatal localization was subcoronal (n = 22), glandular (n = 6), and on the distal shaft (n = 6). In 10 cases urethral catheters was not necessary. A patient develops a proximal fistula successfully treated with 14 days catheterization. Cosmetic and functional results were good in all cases. Extensive urethral mobilization can be done in cases of distal hypospadias and is evidence of the preserved vascularity and viability of the mobilized urethra.
科夫氏手术治疗远端尿道下裂包括对远端尿道进行广泛游离。联合经腺体造瘘和微创尿道成形术对大多数远端尿道下裂患者的治疗很有用。在过去两年中，34例远端型尿道下裂患者接受了科夫氏改良手术。该技术包括无腺体成形术的尿道前移和远端皮肤管状化。原始尿道口位置在冠状沟下（n = 22）、腺体部（n = 6）和阴茎远端干（n = 6）。10例患者无需留置尿道导管。1例患者出现近端瘘，通过14天的导管插入术成功治愈。所有病例的美容和功能效果均良好。在远端尿道下裂病例中可进行广泛的尿道游离，这证明游离尿道的血管供应和活力得以保留。
