To assess the outcome of single stage dorsolateral onlay buccal mucosal urethroplasty for long anterior urethral strictures (>4cm long) using a perineal incision.
From August 2010 to August 2013, 20 patients underwent BMG urethroplasty. The cause of stricture was Lichen sclerosis in 12 cases (60%), Instrumentation in 5 cases (25%), and unknown in 3 cases (15%). Strictures were approached through a perineal skin incision and penis was invaginated into it to access the entire urethra. All the grafts were placed dorsolaterally, preserving the bulbospongiosus muscle, central tendon of perineum and one-sided attachement of corpus spongiosum. Procedure was considered to be failure if the patient required instrumentation postoperatively.
Mean stricture length was 8.5cm (range 4 to 12cm). Mean follow-up was 22.7 months (range 12 to 36 months). Overall success rate was 85%. There were 3 failures (meatal stenosis in 1, proximal stricture in 1 and whole length recurrent stricture in 1). Other complications included wound infection, urethrocutaneous fistula, brownish discharge per urethra and scrotal oedema.
Dorsolateral buccal mucosal urethroplasty for long anterior urethral strictures using a single perineal incision is simple, safe and easily reproducible by urologists with a good outcome.
评估采用会阴切口的单阶段背外侧嵌贴式颊黏膜尿道成形术治疗长段前尿道狭窄(长度>4cm)的疗效。
2010年8月至2013年8月,20例患者接受了颊黏膜移植尿道成形术。狭窄原因:12例(60%)为硬化性苔藓,5例(25%)为器械损伤,3例(15%)原因不明。通过会阴皮肤切口入路,将阴茎纳入切口以显露整个尿道。所有移植物均放置于背外侧,保留球海绵体肌、会阴中心腱及海绵体的单侧附着。如果患者术后需要器械辅助,则认为手术失败。
平均狭窄长度为8.5cm(范围4至12cm)。平均随访22.7个月(范围12至36个月)。总体成功率为85%。有3例失败(1例尿道口狭窄,1例近端狭窄,1例全长复发性狭窄)。其他并发症包括伤口感染、尿道皮肤瘘、尿道褐色分泌物及阴囊水肿。
采用单一会阴切口的背外侧颊黏膜尿道成形术治疗长段前尿道狭窄简单、安全,泌尿外科医生易于掌握,且疗效良好。
