目的:比较镶嵌式唇黏膜和膀胱黏膜在治疗尿道下裂手术后复杂性尿道皮肤瘘手术成功率和并发症发生率。方法:对符合手术指征的55例尿道下裂术后复杂性尿道皮肤瘘患者,随机分成唇黏膜取材组(36例)和膀胱黏膜取材组(19例),于术中分别应用自体游离唇黏膜和膀胱黏膜行尿道成形术,并评估手术并发症和术后尿道皮肤瘘的再发率。结果:镶嵌式唇黏膜和膀胱黏膜在治疗复杂性尿道皮肤瘘术后,均有2例出现尿道皮肤瘘,1例出现尿道狭窄,手术成功率分别为91.7%、84.2%,无统计学差异(P>0.05);术后阴茎外形美观。两组术后并发症发生率也无统计学差异(11.1%vs 26.3%,P>0.05)。结论:镶嵌式唇黏膜和膀胱黏膜修复复杂性尿道皮肤瘘均取得了理想的效果,但唇黏膜修复供材区创伤更小,手术简单快捷,值得在临床上推广应用。
Objective: To compare the success rate and complication rate of complicated urethral skin fistula in the treatment of hypospadias with inlaid lip mucosa and bladder mucosa. Methods: Fifty-five patients with complicated urethral cutaneous fistula after operation for hypospadias were randomly divided into oral mucosa extraction group (36 cases) and bladder mucosa extraction group (19 cases) Mucosa and bladder mucosa underwent urethroplasty, and evaluate the complications of surgery and postoperative urethral skin fistula recurrence rate. Results: There were 2 cases of urethral skin fistula and 1 case of urethral stricture in the treatment of complicated urethral skin fistula with mosaic lip mucosa and bladder mucosa. The successful rates of operation were 91.7% and 84.2%, respectively, with no significant difference ( P> 0.05); postoperative penile appearance. The incidence of postoperative complications was also no significant difference between the two groups (11.1% vs 26.3%, P> 0.05). CONCLUSION: Inlaid lip mucosa and bladder mucosa repair complex urethral skin fistula have achieved the desired results, but the lip mucosa repair donor area less trauma, the operation is simple and quick, it is worth popularizing the clinical application.
