To demonstrate ventral corporoplasty, with tunica vaginalis flap to reconstruct the corpora cavernosa, in a two-stage strategy for proximal hypospadias surgery.
Assessment of residual curvature after complete urethral plate division and transverse superficial cuts in albuginea. Ventral incision of tunica albuginea to elongate the ventral surface of the penis and use of a tunica vaginalis flap to reconstruct the defect in corpora cavernosa. Dorsal preputial island flap was used to cover the penile ventral surface, to be tubularized in a second stage, together with the original urethral plate.
Patient had an uneventful follow-up. Penile aspect was very satisfactory with no residual curvature.
Tunica vaginalis is an attractive alternative for ventral corporoplasty in hypospadia repair and has the advantages of prompt disposability, autologous use, and does not represent an extra cost for treatment.
展示一种两阶段策略下的近端尿道下裂手术中，利用鞘膜突皮瓣重建海绵体的阴茎腹侧成形术。
评估完全切开尿道板和白膜横向浅层切开后残余弯曲度。切开阴茎腹侧白膜以延长阴茎腹侧表面，并使用鞘膜突皮瓣重建海绵体的缺损。采用阴茎腹侧皮岛瓣覆盖阴茎腹侧表面，二期与原始尿道板一起行管状化。
患者随访无异常。阴茎外观非常满意，无残余弯曲。
鞘膜突是尿道下裂修复中阴茎腹侧成形术的一种有吸引力的选择，具有快速处理、自体使用的优点，且不会增加治疗费用。
