The 2 types of urethral injury that can occur during circumcision are urethrocutaneous fistula and urethral distortion secondary to partial glans amputation. We report the surgical repair of these rare injuries.
In 8 patients urethrocutaneous fistulas located on the distal penile shaft or at the coronal margin were managed by splitting the glans and using a Mathieu style skin flap in 4 or vascularized penile skin flap in 4 to bridge the urethral defect. Three patients underwent repair of a hypospadiac deviated urethra secondary to partial glans amputation by 1 cm. of urethral mobilization and repositioning the meatus into a terminal position within the remaining glans tissue.
The 8 patients with urethrocutaneous fistulas voided via a terminal meatus without fistula recurrence at a mean followup of 3.2 years (range 1 to 6). The 3 patients with partial glans amputation and urethral deviation repaired by short urethral advancement had functionally acceptable results, defined as a normal urinary stream, although 1 required meatal dilation postoperatively.
The 2 types of urethral injuries that can occur during circumcision are a subcoronal urethrocutaneous fistula and scarred abnormal urethra from partial glans amputation. The urethrocutaneous fistula can be successfully repaired by splitting the glans and forming a neourethra from a vascularized pedicle flap of penile skin. The abnormal urethra after partial glans amputation is more difficult to repair but repositioning the urethra in a more cosmetic location has restored function.
包皮环切术期间可能发生的两种尿道损伤类型为尿道皮肤瘘和继发于部分龟头切除的尿道扭曲。我们报告了这些罕见损伤的手术修复情况。
8例位于阴茎远端阴茎干或冠状缘的尿道皮肤瘘患者,4例采用劈开龟头并使用马蒂厄式皮瓣,4例采用带血管蒂阴茎皮瓣来桥接尿道缺损。3例因部分龟头切除1 cm继发尿道下裂且尿道偏斜的患者,通过游离尿道1 cm并将尿道口重新定位到剩余龟头组织内的末端位置进行修复。
8例尿道皮肤瘘患者在平均3.2年(范围1至6年)的随访中,经末端尿道口排尿,无瘘复发。3例因部分龟头切除和尿道偏斜而通过短段尿道前移修复的患者,功能结果可接受,定义为尿流正常,尽管有1例术后需要进行尿道口扩张。
包皮环切术期间可能发生的两种尿道损伤类型为冠状沟下尿道皮肤瘘和部分龟头切除导致的瘢痕性异常尿道。尿道皮肤瘘可通过劈开龟头并利用带血管蒂阴茎皮瓣形成新尿道成功修复。部分龟头切除后的异常尿道修复更为困难,但将尿道重新定位到更美观的位置已恢复了功能。
