In order to evaluate the etiology of urethral stricture in our society and outcome of different types of surgical reconstruction used to treat them.
This prospective study was carried out in the Urology and Nephrology Center, at Al-Thawra Modern General and Teaching Hospital, Sana'a, Yemen from July 2003 to July 2007 and included 62 male patients with complete urethral stricture whom underwent Urethral reconstructive surgery. The patients were evaluated by history, local and systemic physical examination, and radiological assessment according to each case.
Patient's age ranged between 3 and 70 years (mean 25.31). Of 55 patients presented to the GER, 31 patients had car accident, 14 patients had gun shot injury, 9 patients fell from high, and one patient had bomb explosion. Five patients had history of traumatized catheterization and urethrocystoscopy, while two patients had history of urethritis. The site of the stricture was at the bulbomembranous area in 43 patients, in the penile urethra in 14 patients, and in bulbous urethra in 5 patients. The length of the urethral stricture was 10-30 mm in 39 patients (63%), <10 mm in 13 patients (21%) and of 30-70 mm in 10 patients (16%). A total of 15 patients (24%) with posterior urethral stricture of 10 mm or less (+2 patients with 1.2 and 1.5 cm), subjected to endoscopic treatment, 37 patients (60%) with stricture >10-30 mm, were underwent anastomotic urethral reconstruction and 10 patients (15%) with stricture >30 mm, were repaired utilizing tissue transfer technique. Follow-up period ranged from 3 months to 2 years (median 15 months), in which recurrent stricture was found in 11 patients (18%), wound dehiscence in 4 patients (6%) and fistula formation in 1 patient (1.5%), while no patient came with erectile dysfunction.
Trauma is the commonest cause of urethral stricture in our country, therefore the control of it will decrease extremely the urethral stricture disease. No one technique is suitable for all types of the stricture, and the surgeon should be familiar with the different techniques and choose the most suitable one according to the case he deals with.
评估我们社会中尿道狭窄的病因以及不同类型的手术重建方法的治疗效果。
本前瞻性研究于 2003 年 7 月至 2007 年 7 月在也门萨那的 Thawra 现代综合教学医院泌尿科和肾脏病中心进行,纳入 62 例完全性尿道狭窄的男性患者,所有患者均接受尿道重建手术。根据每位患者的具体情况,通过病史、局部和全身体格检查以及影像学评估对患者进行评估。
患者年龄 3-70 岁,平均 25.31 岁。55 例在 GER 就诊的患者中,31 例因车祸,14 例因枪伤,9 例因高处坠落,1 例因爆炸受伤。5 例有创伤性导尿和尿道膀胱镜检查史,2 例有尿道炎史。尿道狭窄部位:球膜部 43 例,阴茎部 14 例,球部 5 例。尿道狭窄长度:39 例(63%)<10mm,13 例(21%)10-30mm,10 例(16%)30-70mm。15 例(24%)后尿道狭窄<10mm(其中 2 例分别为 1.2cm 和 1.5cm)患者行内镜治疗,37 例(60%)>10-30mm 患者行吻合口尿道重建术,10 例(15%)>30mm 患者行组织转移技术修复。随访 3 个月至 2 年(中位数 15 个月),11 例(18%)复发,4 例(6%)切口裂开,1 例(1.5%)瘘形成,无勃起功能障碍患者。
创伤是我国尿道狭窄的常见原因,因此控制创伤可显著降低尿道狭窄的发生率。没有一种技术适用于所有类型的狭窄,外科医生应熟悉不同的技术,并根据所处理的病例选择最合适的技术。
