创伤性尿道狭窄术后尿道超声研究:尿道狭窄术后吻合口形态超声分型

目的　研究创伤性尿道狭窄术后尿道吻合口形态学特征。方法　对 92例尿道狭窄术后一年内的患者进行超声检测。结果　将吻合口形态学表现分为 6种类型 :疤痕型 (38例 ) ,假道型 (10例 ) ,活瓣型 (5例 ) ,闭合不全型 (9例 ) ,吻合口腔道形态异常型 (7例 ) ,基本正常型 (2 3例 )。各型均有自身的声像图特征及相应的排尿表现。结论　尿道吻合口形态的超声研究为正确评价尿道狭窄术后的疗效奠定了形态学基础。

A Study of Sonourethrography on Traumatogenic Urethral Strictures Postoperatively : Classif ication of Urethral Anastomotic Site Morphologically by Ultrasound

Objective To study morphologic characteristics of urethral anastomotic site postoperatively in urethral stricture by injury. OMethods Ninety-two patients with the urethral stricture underwent sonourethrography within one year after operation ,including open urethroplasty in 68 cases ,internal urethrotomy in 25 cases. Results The urethral morphologic changes in 92 patients were classified into six types :scar type (type I) in 38 cases ; false passage type (type II) in 10 ; flap valve type (type III) in 5 ;closure insufficiency type (type IV) in 9 ;abnormal lumen type (type V) in 7 ;normal type (type VI) in 23. Each type had its own sonographic appearance and corresponding clinical presentation. Conclusion A sonourethrographic study on morphology of urethral anastomotic site will lay down morphological base in assessing postoperative micturition and further management correctly.
