目的 :探索颊黏膜在修复女童复杂性前尿道缺损中的应用价值。方法 :采用部分耻骨劈开联合阴道前庭切口 ,截取相应大小的口腔颊黏膜作管状成形Ⅰ期修复女童前尿道缺损 3例。结果 :3例女童术后均排尿通畅 ,最大尿流率为 19.6～ 2 4 .4ml/s,平均为 2 0 .5ml/s,尿道造影示尿道通畅。结论 :口腔颊黏膜具有取材方便、对患者创伤小、抗感染能力强等特性 ,是一种较好的尿道替代材料 ,尤其适合尿道狭窄段 <5cm的患者。
Objective: To explore the value of buccal mucosa in repairing the complexity of urethra in girls. Methods: Partial pubis splitting combined with vaginal vestibular incision was used to intercept the buccal mucosa of the corresponding size for tubular repair in 3 cases of anterior urethral defect in girls. Results: All the 3 girls underwent urinary patency. The maximum uroflow rate was 19.6-2.44 ml / s with an average of 20.5 ml / s. Urethral angiography showed urethral patency. Conclusion: Buccal mucosa is a good material for urinary tract replacement, which is especially suitable for patients with urethral stricture less than 5cm because of its convenient material drawing, small trauma to patients and strong anti-infective ability.
