自1988年6月至1994年7月,我们采用自行设计的包皮帽瓣法对7例冠状沟型尿道下裂患儿施行尿道成形,年龄最小5岁,最大12岁,均为初治病例。其中,4例伴有不同程度的阴茎下弯畸形和尿道外口狭窄。皮瓣设计最大4 cm×2 cm,最小2.0 cm×1.5 cm。术后尿道外口均位于龟头顶端,阴茎形态自然,达到了预期的疗效。手术方法:先扩大狭窄的尿道外口并行耻骨上膀胱造瘘术,矫治阴茎下弯畸形。自尿道外口近端至阴茎头顶丰富的包皮帽部设计一斜形的“〇”形包皮帽瓣,皮瓣大小依患者年龄、阴茎大小进行调整。一
From June 1988 to July 1994, we used a self-designed foreskin cap flap method to treat urethroplasty in 7 patients with coronal hypospadias, the youngest 5 years old and the oldest 12 years old, all of whom were newly diagnosed. Among them, 4 cases were associated with varying degrees of penile deformity and urethral stricture. Flap design up to 4 cm × 2 cm, the smallest 2.0 cm × 1.5 cm. Postoperative urethral orifice are located in the top of the glans penis, natural morphological, to achieve the desired effect. Surgical methods: First to expand the narrow external urethral parallel suprapubic cystostomy, correction of penile deformity. From the proximal urethral orifice to the top of the penis cap rich foreskin design a beveled “〇 ” shaped foreskin flap, flap size according to the patient’s age, adjust the size of the penis. one
