摘要目的 分析改良YV型膀胱颈部重建术治疗经尿道前列腺电切(TURP)术后难治性膀胱颈部挛缩(bladder neck contracture,BNC)的临床疗效.方法 回顾性分析2013年6月至2016年3月收治的11例曾多次(≥2)内镜手术治疗失败的难治性BNC患者的临床资料.患者年龄56～73岁,平均63.7岁.患者均以TURP术后不同程度的排尿困难为主诉就诊,采用改良YV型膀胱颈部重建术进行治疗,通过在膀胱前壁做T型切口,获取2个血供良好的无张力膀胱壁瓣,用于重建并扩大膀胱颈部.结果 11例患者术后随访3 ～ 24个月,平均14.6个月.治愈9例,无手术导致的尿失禁发生;2例术后出现排尿困难,经再次行膀胱颈部冷刀切开后排尿通畅.结论 改良YV型膀胱颈部重建术可有效扩大狭窄的膀胱颈口,同时避免尿道外括约肌损伤,对于难治性BNC患者是一个可行的治疗方式.

abstractsObjective To investigate the clinical efficacy of modified YV-plasty for refractory bladder neck contracture (BNC) caused by transurethral resection of prostate (TURP).Methods From June 2013 to March 2016,11 patients with BNCs secondary to TURP were included in this study.Their mean age was 63.7 years (range,56-73 years).All patients presented voiding difficulty and failed after 2 or more prior endoscopic treatments.Modified YV-reconstruction of bladder neck was performed,by incising the anterior wall of bladder neck in a T-shaped manner,and creating two well-vascularized and tension-free flaps,which offer the possibility to reconstruct a wide bladder neck.Results After a mean follow-up of 14.6 months (ranging 3-24 months),successful outcome was achieved in 9 patients without incontinence secondary by surgery.Recurrent voiding difficulty developed in 2 patients,which was cured after a following endoscopic treatment.Conclusion A wider bladder neck can be obtained through modified YV-reconstruction of bladder neck,while avoiding external urethral sphincter injury.It is an available option for refractory bladder neck contracture.
