摘　　要：目的探讨阴茎游离皮片背侧镶嵌成形术治疗经尿道前列腺切除术(TURP)术后前尿道狭窄的临床疗效。方法回顾性分析2010年1月至2017年12月昆明医科大学附属延安医院收治的16例TURP术后并发前尿道狭窄患者的病例资料。年龄58~75岁,平均64.3岁。TURP术后至确诊前尿道狭窄时间1~12个月,平均3.5个月。术前采用尿道扩张器探查或尿道镜检,并完善尿道造影以明确诊断。5例为阴茎部尿道狭窄,11例为阴茎阴囊交界处尿道狭窄;狭窄段长度2~5 cm,平均3.4 cm。术前最大尿流率(5.3±2.7)ml/s。11例经>6个月定期尿道扩张治疗效果不佳,5例经1~2次尿道内切开+尿道扩张治疗效果不佳。16例均行阴茎游离皮片背侧镶嵌成形术。蛛网膜下腔麻醉联合硬膜外麻醉,患者取平卧位。用尿道扩张器明确狭窄段远端,自尿道腹侧纵行切开皮肤、皮下,切口长度依据术前尿道造影结果,在狭窄段长度基础上延长0.5 cm。游离狭窄段尿道左右两侧并纵行切开狭窄段尿道海绵体腹侧,切开长度上下各延长0.5 cm至正常尿道黏膜,用牵引线沿两侧牵开腹侧尿道边缘,切开对应的尿道背侧中线直至白膜,将背侧切开的尿道边缘与白膜分离,使白膜上形成一个椭圆形区域。按椭圆形大小取阴茎包皮全层厚皮片,皮片大小超越椭圆形区域边缘约0.3 cm,用6-0可吸收线将游离皮片覆盖于此椭圆形区域上(皮肤面于尿道内侧),游离皮片边缘与背侧切开的尿道边缘间断缝合,多针间断缝合皮片表面于阴茎海绵体床面。用硅胶尿管作为新尿道的支架管,6-0可吸收线关闭切开的尿道海绵体腹侧,采用多层肉膜缝合加盖防止漏尿,逐层缝合筋膜及皮肤。5-0可吸收线间断缝合包皮取材区的创面。结果本组16例手术均顺利完成。手术时间90~120 min,平均102.3 min。术中出血量10~30 ml,平均16.8 ml。术后3周拔除尿管后所有患者排尿困难症状均消失。�Objective To investigate the clinical efficacy of dorsal mosaic surgery with penis free flap for the treatment of anterior urethral stricture after TURP.Methods We analyzed the clinical data of the patients with anterior urethral stricture after TURP from January 2010 to December 2017 in Yan′an hospital affiliated to Kunming medical university retrospectively.The patients'age ranged from 58 to 75 years,with an average of 64.3 years.The time from TURP to the diagnosis of anterior urethral stricture was 1-12 month,with an average of 3.5 months.5 cases were urethral stricture at penis segment,11 cases were urethral stricture at the junction of penis and scrotum,and the length of the narrow urethra was 2-5 cm,with an average of 3.4cm.The average maximum uroflowmetry in preoperative was(5.3±2.7)ml/s.11 cases were treated with regular urethral dilatation and the treatment durable time was more than 6 months,5 cases were treated with intraurethral incision combined with urethral dilatation(1 or 2 times).16 cases were not effective after receiving the above treatment,so that all cases were treated with dorsal mosaic surgery with penis free flap.Subarachnoid anesthesia combined with epidural anesthesia,the patient took the supine position.The distal end of urethral stricture was defined by urethral dilator.Incision from the ventral side of the urethra.The length of the incision was extended 0.5 cm based on the length of urethral stricture in urethral angiography.Anatomize the left and right sides of the urethral stricture and longitudinally incision the ventral side of the urethral cavernous body.The length of the incision was extended 0.5 cm to the normal urethral mucosa.The traction line retracts the ventral urethral edge along both sides.The corresponding medial line of the dorsal urethra was incised to the tunica albuginea,and the urethral edge of the dorsal side was separated from the tunica albuginea to form an elliptical region on the tunica albuginea.According to the size of the ellipse,the full thickness of th
