Repair of bulbar strictures using anastomotic techniques may cause sexual complications, while 1-side graft urethroplasties may not be sufficient to provide an adequate lumen in narrow strictures. We evaluated the urinary and sexual results of a 2-sided dorsal plus ventral graft urethroplasty by preserving the narrow urethral plate in tight strictures.
Between 2002 and 2010, 105 men with bulbar strictures underwent dorsal plus ventral graft urethroplasty. The results are reported in a homogeneous group of 73 of 105 cases in which buccal mucosa was used as a graft with findings after 1 year or more of followup. The urethra was opened ventrally, and the exposed dorsal urethra was incised in the midline to create a raw area over the tunica albuginea where the first graft was placed dorsal-inlay. Thereafter the urethra was augmented by the ventral-onlay second graft and the spongiosum was closed over itself. Successful urethral reconstruction was defined as normal voiding without the need for any postoperative procedure. Postoperative sexual dysfunction was investigated using a validated questionnaire.
Mean followup was 48.9 months and mean stricture length was 3.3 cm. Of these 73 cases 64 (88%) were successful and 9 (12%) were treatment failures with re-stricture. Furthermore, of 49 of 73 cases who were preoperatively sexually active, none reported postoperative erectile impairment and all were satisfied with their sexual life.
In cases of tight bulbar stricture the dorsal plus ventral buccal mucosa graft provides adequate urethral augmentation by preserving the urethral plate and avoiding postoperative sexual complications.
采用吻合技术修复球部狭窄可能导致性功能障碍,而单侧移植物尿道成形术可能不足以在狭窄的狭窄部位提供足够的管腔。我们通过保留狭窄尿道板评估了在紧密狭窄部位进行双侧背侧加腹侧移植物尿道成形术的尿和性功能结果。
2002 年至 2010 年,105 名球部狭窄患者接受了背侧加腹侧移植物尿道成形术。在 105 例患者中有 73 例的结果在一组同质患者中进行了报道,其中 73 例使用颊黏膜作为移植物,随访 1 年或更长时间后发现。尿道在腹侧切开,暴露的背侧尿道在中线切开,在白膜上创建一个原始区域,将第一个移植物置于背衬镶嵌中。此后,通过腹侧镶嵌的第二个移植物增加尿道,并将海绵体自身封闭。正常排尿而无需任何术后程序定义为成功的尿道重建。术后性功能障碍使用经过验证的问卷进行调查。
平均随访时间为 48.9 个月,平均狭窄长度为 3.3 厘米。在这 73 例中,64 例(88%)成功,9 例(12%)因再狭窄而治疗失败。此外,在 73 例术前有性生活的患者中,有 49 例无术后勃起功能障碍报告,所有患者对性生活均满意。
在球部紧窄的情况下,通过保留尿道板并避免术后性功能并发症,背侧加腹侧颊黏膜移植物可提供足够的尿道增强。
