目的 :探讨尿道下裂尿道成形术后尿道狭窄的治疗。方法 :对尿道下裂尿道成形术后发生尿道狭窄 2 9例患者临床资料进行分析。结果 :尿道外口狭窄 2 1例 ,其中 11例经扩张治愈 ,另 10例分别行狭窄的外口切开及狭窄段切除阴茎包皮转移皮瓣尿道外口整形术。吻合口狭窄 8例 ,对其中 2例行吻合口狭窄直接扩张 ,另 6例行狭窄部切除端端吻合术 ,均获成功。结论 :尿道下裂尿道成形术后尿道狭窄发生的主要原因是成形尿道皮瓣的设计不合理、血供差、感染、原尿道外口狭窄或发育不良处未切除以及缝合材料选用不当。对尿道外口狭窄主要行扩张治疗 ,对吻合口狭窄应以手术治疗为主。
Objective: To investigate the treatment of urethral stricture after hypospadia urethroplasty. Methods: Clinical data of 29 patients with urethral stricture after hypospadiac urethroplasty were analyzed. Results: 21 cases of urethral stenosis, of which 11 cases were cured by expansion, and the other 10 cases were stenosis and stenosis resection of the penis foreskin transfer flap urethral plastic surgery. Anastomotic stenosis in 8 cases, of which 2 cases of anastomotic stenosis direct expansion, the other 6 cases of stenosis resection end anastomosis, were successful. Conclusion: The main reason of urethral stenosis after hypospadial urethroplasty is the unreasonable design of the shaped urethra flap, poor blood supply, infection, stenosis of the original urethral orifice or dysplasia and inappropriate use of suture material. Urethral stenosis of the main line of expansion treatment, anastomotic stenosis should be based on surgical treatment.
