摘要
目的:为了提高小儿尿道狭窄治疗的效果。方法:应用螺旋形记忆合金支架治疗儿童尿道狭窄9例,年龄最小的4岁,最大12岁,平均7.5岁,其中7例陈旧性骨盆骨折后尿道断裂,2例尿道下裂尿道成形术后尿道狭窄,共放置记忆合金支架11次。结果:2例尿道损伤患儿由于记忆合金支架错位及倒伏而形成梗阻,更换合金支架后梗阻解除;1例尿道下裂尿道口狭窄患儿置入支架后1个月自行脱落,脱落后未再发生狭窄;其余患儿经随诊,对支架无不良反应,无任何不适,排尿功能良好。结论:记忆合金支架在治疗和预防儿童尿道狭窄中有肯定的效果,螺旋形支架在尿道内肉芽组织不易长入,但偶尔会发生错位和倒伏的并发症,因此对支架制作工艺的进一步改进将有助于进一步提高疗效。
Objective:To summarise the preliminary experience of memory alloy frame in the treatment for urethal stricture.Methods:From Jan.1995 to Jan.1996,the memory alloy frame was used for eleven times in 9 patients with urethral stricture.Among them,post-traumatic stric- ture was in 7,a complication of urethroplasty in 2.Results:All patients have got normal urina- tion with a follow-up from 6 mons to 2 years,except 2 needed a replacement due to malposition of the frame.Conclusions:Memory alloy frame is helpful in the treatment of urethral stricture in children.
