The aim of our study was to evaluate the role of paraurethral spongial tissue plus dartos flap using an additional urethral cover to prevent fistula formation in patients who underwent surgery with the Snodgrass technique.
A retrospective study was performed on 161 patients aged 10 months to 15 years who underwent midpenile and distal hypospadias repair using the Snodgrass technique. The patients were assigned to one of two groups. In Group I (75 patients), the neourethra was covered with the dartos flap, and in Group II (86 patients), the neourethra was covered with the dartos flap plus spongioplasty.
Urethral fistulae were encountered in six cases (8%) in Group I, and no fistulae were encountered in Group II.
The use of corpus spongiosum as an intermediate layer in urethral coverage, combined with the dartos flap, reduces the likelihood of fistula formation. This procedure can be applied easily and effectively to prevent the formation of fistulae.
本研究旨在评估在接受 Snodgrass 技术手术的患者中，使用额外尿道覆盖物预防瘘形成的尿道海绵体组织加球海绵体肌瓣的作用。
对 161 名年龄在 10 个月至 15 岁之间的患者进行了回顾性研究，这些患者接受了 Snodgrass 技术的阴茎中部和远端尿道下裂修复。患者被分为两组。在第 I 组（75 例）中，新尿道用球海绵体肌瓣覆盖，在第 II 组（86 例）中，新尿道用球海绵体肌瓣加海绵体成形术覆盖。
第 I 组有 6 例（8%）出现尿道瘘，第 II 组未出现尿道瘘。
将尿道海绵体作为尿道覆盖的中间层，结合球海绵体肌瓣，可降低瘘形成的可能性。该手术操作简单有效，可有效预防瘘的形成。
