Urethral reconstruction has evolved in the last several decades with the introduction of various techniques including fasciocutaneous skin flaps and buccal mucosal grafts. However, distal urethral strictures have continued to be a reconstructive challenge due to tendency for adverse cosmetic outcomes, risks of glans dehiscence or fistula formation, and stricture recurrence.
The surgical options for treatment of distal urethral strictures have changed throughout the years; however, there is no one universally accepted technique for their treatment. The current trend for treatment is shifting away from multi-staged procedures or the use of local skin flaps to single-stage transurethral procedures that utilize buccal mucosa with glans preservation. This chapter will describe the evolution of distal urethral stricture treatments tracking gradual improvements and modifications over time. The different interventions include transurethral approaches, such as dilations and visual urethrotomy, meatotomy, and meatoplasty/urethroplasty techniques including genital skin flaps and single- and double-stage repairs with buccal mucosal grafts.
在过去几十年中,随着包括筋膜皮瓣和颊黏膜移植在内的各种技术的引入,尿道重建技术不断发展。然而,由于存在不良美容效果、龟头裂开或瘘管形成的风险以及狭窄复发等问题,远端尿道狭窄仍然是一个重建难题。
多年来,治疗远端尿道狭窄的手术选择不断变化;然而,目前尚无一种被普遍接受的治疗技术。当前的治疗趋势正从多阶段手术或使用局部皮瓣转向采用保留龟头的颊黏膜的单阶段经尿道手术。本章将描述远端尿道狭窄治疗方法的演变,追踪随着时间推移逐渐取得的改进和改良。不同的干预措施包括经尿道方法,如扩张术、直视下尿道切开术、尿道口切开术,以及尿道口成形术/尿道成形术技术,包括生殖器皮瓣以及采用颊黏膜移植的单阶段和双阶段修复术。
