目的探讨渐进式尿道扩张术并留置Foley导尿管预防尿道下裂术后尿道狭窄的效果。方法对2010-2012年182例因尿道下裂行一期尿道成形术患儿术后行渐进式尿道扩张术并留置Foley导尿管,观察预防尿道狭窄的效果。结果 182例患儿拔出导尿管后1年内出现尿道狭窄的仅8例,其中仅1例再次行尿道狭窄段切开并尿道成形术,余7例经再次尿道扩张并留置Foley导尿管后治愈。结论尿道下裂尿道成形术后行渐进式尿道扩张并留置Foley导尿管预防尿道狭窄效果满意,去除导尿管后1年内再次出现尿道狭窄者可再次行尿道扩张术并留置Foley导尿管,仍可取得较好的疗效。
Objective To investigate the effect of progressive urethral dilatation and indwelling Foley catheter to prevent urethral stricture after hypospadias operation. Methods A total of 182 cases of urethroplasty undergoing primary urethroplasty from 2010 to 2012 were treated with progressive urethral dilatation and catheterization of Foley catheter to observe the effect of preventing urethral stricture. Results Only 182 patients with urethral stricture within one year after removing the catheter were found in 182 patients. Only 1 patient underwent urethroplasty and urethroplasty again, and the remaining 7 patients were re-urethral dilatation and catheterization After the cure. Conclusions Progressive urethral dilatation and urethral stricture retention after urethral dissection with urethral catheterization are satisfactory. Urethral stricture may occur again within 1 year after urethral catheter removal. Urethral dilatation may be performed again and Foley catheter may be placed. Still get better curative effect.
