One-stage urethral reconstruction was performed using a free graft of labial mucosa and combined labial/bladder mucosa. We present the results of this technique in 12 cases that had a minimum follow-up period of 3 years. Eleven patients had medium penile or posterior hypospadias and one had chordee penis without hypospadias. Urethroplasty with labial mucosa was performed by two techniques: labial mucosa used alone or combined with bladder mucosa. The labial mucosa was harvested from the inner surface of the upper and/or lower lip, depending on which method was used. Seven patients, six with medium penile or posterior hypospadias and 1 with chordee without hypospadias, were given a labial mucosa graft alone; the urethral gap was 3.5 to 6 cm. The other five cases, all with posterior hypospadias, were treated by combined labial/bladder mucosa graft urethroplasty: the urethral gap was 6 to 13 cm. Follow-up (at 3 to 4 1/2 years) showed no complications apart from a urethral fistula in one patient and mild stenosis on the anastomosis in four cases, which required urethral dilatations in the first month after surgery.
采用唇黏膜游离移植和唇/膀胱黏膜联合移植进行一期尿道重建。我们展示了该技术应用于12例患者的结果，这些患者的最短随访期为3年。11例患者患有中度阴茎型或阴茎阴囊型尿道下裂，1例患有阴茎弯曲但无尿道下裂。唇黏膜尿道成形术采用两种技术：单独使用唇黏膜或与膀胱黏膜联合使用。根据所采用的方法，唇黏膜取自上唇和/或下唇的内表面。7例患者，6例患有中度阴茎型或阴茎阴囊型尿道下裂，1例患有阴茎弯曲但无尿道下裂，仅接受唇黏膜移植；尿道缺损长度为3.5至6厘米。另外5例患者，均患有阴茎阴囊型尿道下裂，接受唇/膀胱黏膜联合移植尿道成形术治疗；尿道缺损长度为6至13厘米。随访（3至4.5年）显示，除1例患者出现尿道瘘，4例患者吻合口轻度狭窄（术后第一个月需要进行尿道扩张）外，无其他并发症。
