Abstract

Metoidioplasty denotes the creation of a neophallus out of the hormonally hypertrophied clitoris. Construction of an esthetically acceptable male-like genitalia while enabling micturition in standing position are the primary goals. Herein, we aim to review the literature regarding masculinizing gender-affirming genital surgery in the form of metoidioplasty, focusing on the steps related to urethral lengthening and reconstruction, and describe the authors' preferred surgical technique. Clitoral release, division of the urethral plate, native urethral lengthening with anterior vaginal wall flap, and neourethral tubularization using a combination of buccal mucosa graft and labia minora flap(s) seem to provide the best result in terms of urinary outcomes. This is reflected in a greater urethral length, higher probability of standing micturition, and lower incidence of fistula. Urethral complications, which can be encountered in up to 15% of the patients, may necessitate additional procedures. Some of the studies have reported successful penetrative intercourse following metoidioplasty. Case series about different metoidioplasty techniques do not allow head-to-head comparison due to non-standardized reporting and outcome assessment. Metoidioplasty can be offered to transgender men with sufficiently hypertrophied clitoris who wish to avoid a complicated, multistage, flap-based total phalloplasty, or for those individuals considering phalloplasty at a later date.

摘要

阴茎成形术是指利用激素刺激增大的阴蒂构建一个新阴茎。构建出外形美观且类似男性的生殖器,并能实现站立排尿,是主要目标。在此,我们旨在回顾有关以阴茎成形术形式进行的性别肯定性男性化生殖器手术的文献,重点关注与尿道延长和重建相关的步骤,并描述作者偏爱的手术技术。阴蒂松解、尿道板分离、利用阴道前壁皮瓣进行自体尿道延长,以及联合使用颊黏膜移植物和小阴唇皮瓣进行新尿道管状化,在排尿结果方面似乎能提供最佳效果。这体现在尿道长度更长、站立排尿概率更高以及瘘管发生率更低。尿道并发症在高达15%的患者中可能会出现,这可能需要额外的手术。一些研究报告了阴茎成形术后成功的插入式性交。由于报告和结果评估不规范,关于不同阴茎成形术技术的病例系列研究无法进行直接比较。阴茎成形术可提供给阴蒂充分增大、希望避免复杂的多阶段皮瓣法全阴茎成形术的跨性别男性,或那些考虑日后进行阴茎成形术的个体。
