目的

评价倒"J"皮瓣螺旋缝合隧道法成形阴茎头段尿道及U型支架管引流在治疗重度尿道下裂的疗效。

方法

回顾性分析2019年4月至2023年12月在我院行尿道下裂分期手术的25例重度尿道下裂患儿资料。所有患儿均一期先行阴茎下弯矫正,采用包皮内板腹侧转移术6个月后行二期带蒂包皮卷管尿道成形术,阴茎头段尿道采用倒"J"皮瓣螺旋缝合隧道法成形,并采用U型支架管引流。

结果

25例患儿中出现尿瘘6例(24%),所有病例尿道口位于龟头前端,阴茎外观好。

结论

倒"J"皮瓣螺旋缝合隧道法成形阴茎头段尿道及U型支架管引流二期尿道成形术术后尿道口位于阴茎头,操作简单,尿道狭窄发生率低,阴茎外观好。

Objective

To evaluate the efficacy of the inverted "J" flap helical suture tunnel technique for neomeatus formation and U-shaped stent tube drainage in the treatment of severe hypospadias.

Methods

A retrospective analysis was conducted on 25 patients with severe hypospadias who underwent staged hypospadias repair in our hospital from April 2019 to December 2023. All patients first underwent correction of penile curvature (first stage). Six months later, a second-stage tubularized preputial flap urethroplasty was performed. The neomeatus was created using the inverted "J" flap helical suture tunnel technique, and a U-shaped stent tube was used for urinary diversion.

Results

Among the 25 patients, urethrocutaneous fistula occurred in 6 cases (24%). The urethral meatus was located at the tip of the glans in all cases, and the penile appearance was satisfactory.

Conclusion

The second-stage urethroplasty using the inverted "J" flap helical suture tunnel technique for neomeatus formation combined with U-shaped stent tube drainage results in a glanular meatus, is simple to perform, has a low incidence of urethral stricture, and provides satisfactory penile appearance.
