This report describes the use of a tubularized random flap for the curative treatment of recurrent anterior urethral stricture. Under the condition of pendulous lithotomy and suprapubic cystostomy, the urethral stricture was removed via a midline ventral penile incision followed by elevation of the flap and insertion of an 18-Fr catheter. Subcutaneous buried interrupted sutures were used to reapproximate the waterproof tubularized neourethra and to coapt with the neourethra and each stump of the urethra, first proximally and then distally. The defect of the penile shaft was covered by advancement of the surrounding scrotal flap. The indwelling catheter was maintained for 21 days. A 9 month postoperative cystoscopy showed no flap necrosis, no mechanical stricture, and no hair growth on the lumen of the neourethra. The patient showed no voiding discomfort 6 months after the operation. The advantages of this procedure are the lack of need for microsurgery, shortening of admission, the use of only spinal anesthesia (no general anesthesia), and a relatively short operative time. The tubularized unilateral penile fasciocutaneous flap should be considered an option for initial flap urethroplasty as a curative technique.
本报告描述了使用管状化随意皮瓣根治性治疗复发性前尿道狭窄的情况。在悬垂位截石术和耻骨上膀胱造瘘的条件下,经阴茎腹侧中线切口切除尿道狭窄,随后掀起皮瓣并插入18F导管。采用皮下埋藏间断缝合将防水的管状化新尿道重新对合,并使其与新尿道及尿道各残端吻合,先近端后远端。阴茎体部的缺损通过推进周围阴囊皮瓣覆盖。留置导管21天。术后9个月的膀胱镜检查显示皮瓣无坏死、无机械性狭窄,新尿道腔内无毛发生长。患者术后6个月排尿无不适。该手术的优点包括无需显微手术、缩短住院时间、仅使用脊髓麻醉(无需全身麻醉)以及手术时间相对较短。管状化单侧阴茎筋膜皮瓣应被视为作为一种根治技术进行初始皮瓣尿道成形术的一种选择。
