中文摘要：
目的：探讨带蒂睾丸鞘膜和阴囊肉膜做为尿道覆盖材料在尿道板纵切卷管尿道成形术中的疗效。方法：对120例尿道下裂患儿进行尿道板纵切卷管尿道成形术,其中采用带蒂睾丸鞘膜做为尿道覆盖材料61例,以阴囊肉膜做为尿道覆盖材料59例。比较两种尿道覆盖材料在手术时间、出血量以及尿道瘘等差异。结果：术后随诊2个月至6年,两组手术时间差异无统计学意义（F=0.141,P〉0.05）;出血量差异无统计学意义（F=1.409,P〉0.05）;睾丸鞘膜组尿道瘘5例（8.2%）,阴囊肉膜组尿道瘘13例（22.0%）,两组差异有统计学意义（χ~2=4.504,P〈0.05）。结论：带蒂睾丸鞘膜做为尿道覆盖材料在尿道板纵切卷管尿道成形术中的疗效优于阴囊肉膜。
英文摘要：
Objective： To compare the clinical effects of vascularized tunica vaginalis flap and dartos fascia tis-sues as a additional layer in tubularized incised plate urethroplasty. Methods： 120 patients with penile hypospadias who were treated using a tubularized incised plate urethroplasty. 61 cases used vascularized tunica vaginalis flap as layer, 59 cases used dartos fascia tissues. Operation time, blood loss volume, postoperative complication rate were documented and analyzed between the two groups. Results： The follow-up period ranging from 2 months to 6 years. There is no difference between two groups in operation time （P〉0. 05） and blood loss volume （P〉0. 05）. There were statistical differences in the incidence of the urethral fistula（P〈0. 05）. Conclusion： Vascularized tunica vagina-lis flap has the advantage of low surgical complication rates in comparison with dartos fascial tissues in tubularized incised plate urethroplasty.
