摘要
目的探讨阴囊肉膜下筋膜血管网蒂皮瓣重建尿道的方法。方法1998年3月~2004年8月对先天性尿道畸形患者8例及尿道下裂术后并发多孔尿瘘、尿道狭窄和阴茎弯曲畸形23例,采用阴囊肉膜下筋膜血管网蒂皮瓣修复缺损的尿道。年龄6~34岁,平均20.3岁,皮瓣宽度:儿童为1.5~2.5cm,成人为2.5~3.5cm,长度可为宽度的1.5~2倍。其中尿道下裂阴茎型9例;阴茎阴囊型10例;阴囊型7例,其中3例为儿童伴阴囊分裂,尿道开口于阴囊分裂沟中;会阴型5例,为男性假两性畸形。结果术后皮瓣均成活,切口愈合良好,期愈合24例,期愈合7例。仅1例拔除支架管后发生尿瘘,嘱患者排尿时按压瘘口,2周后闭合。27例获随访1~4年,2例术后1年阴茎稍下弯,其余患者阴茎形态及功能良好。结论应用阴囊肉膜下筋膜血管网蒂皮瓣重建缺损的尿道疗效满意,是一种修复尿道下裂术后并发症较理想的方法。
Objective To introduce the application of the scrotal flap on reconstructing partial urethra defect. Methods From March 1998 to August 2004, 31 patients with urethra defect were treated with scrotal flap. Their ages ranged from 6 to 34 years. Thirty one patients included 8 cases of congenital deformity of urethra and 23 cases of complication of urethral fistula, urethral stenosis and phallus bend after hypospadias repair. The flap widths were 1.5- 2.5 cm in child and 2. 5-3.5 cm in adult. The flap length was 1.5-2.0 times as much as the width. Nine cases were classified as penile type, 10 cases as penoscrotal type, 7 cases as scrotal type (3 children in association with cleft scrotum) and 5 cases as perrineal type because of pseudohermaphroditism. Urethroplasty was given by scrotal fascia vascular net flap to reconstruct urethra defect. Results All the flaps survived, and the incision healed well. Twentyfour cases achieved healing by first intention and 7 cases by second intention. And fistula occurred and healed after 2 weeks in 1 case. 27 cases were followed up 1-4 years, 2 cases had slight chordee, the others were satisfactivly. Conclusion Urethroplasty with scrotal fascia vascular net flap is an ideal method for the partial defect urethra.
