We present 2 variants of the penile disassembly technique for epispadias repair that refine some details of the Mitchell technique. In some cases the urethral plate retracts and shortens, and there may be poor vascularization at the most distal portion. In addition, when the neurovascular bundles of the separated hemicorporeal glanular bodies are intact, it is difficult to achieve excellent correction of dorsal chordee.
Between 1995 and 1998 we performed the modified Mitchell technique in 11 boys 2 to 14 years old using 1 of 2 variants. For variant 1 the hemiglans and urethral plate remain connected by a small tissue bridge to avoid shortening the urethral plate and ensure a better blood supply. For variant 2 each corporeal body is dissected from the glans cap and neurovascular bundle to achieve complete mobility. This procedure enables ideal mobility of the corporeal bodies as well as curvature repair. When corporeal rotation was unsuccessful, we corrected persistent dorsal chordee using the Ransley corporotomy with corporostomy in 2 patients and with dermal grafting in 1.
Mean followup was 17 months (range 6 to 30). Dorsal curvature was corrected in all cases. Cosmetic appearance was good. Complications included meatal stenosis and urethral fistula in 1 case each.
Our variants of epispadias repair may be good alternatives to the Ransley and Mitchell complete penile disassembly techniques.
我们介绍两种阴茎拆解技术用于尿道上裂修复的变体,这些变体改进了米切尔技术的一些细节。在某些情况下,尿道板会回缩和缩短,并且最远端部分可能存在血管化不良的情况。此外,当分离的半阴茎海绵体的神经血管束完整时,很难实现对背侧阴茎弯曲的完美矫正。
1995年至1998年间,我们对11名2至14岁的男孩采用两种变体中的一种进行了改良米切尔技术。对于变体1,半阴茎头和尿道板通过一个小组织桥相连,以避免尿道板缩短并确保更好的血液供应。对于变体2,将每个阴茎海绵体从阴茎头帽和神经血管束上分离,以实现完全的活动度。此操作可使阴茎海绵体获得理想的活动度并矫正弯曲。当阴茎旋转不成功时,我们对2例患者采用兰斯利阴茎海绵体切开术并造瘘,对1例患者采用真皮移植来矫正持续的背侧阴茎弯曲。
平均随访17个月(范围6至30个月)。所有病例的背侧弯曲均得到矫正。外观良好。并发症包括1例尿道口狭窄和1例尿道瘘。
我们的尿道上裂修复变体可能是兰斯利和米切尔完全阴茎拆解技术的良好替代方法。
