目的探讨小儿肾盂成形术后拔除肾造瘘支架管时限。方法从2006年2月至2008年12月,肾盂输尿管交接部梗阻患儿48例。男32例,女16例,年龄12～36月,平均年龄25月,均采用离断式肾盂成行术,分别于术后2周、3周拔除肾造瘘支架管。结果48例患儿全部都进行随访,随访时间为1～33个月,平均随访时间为15个月。2周后拔管有2例肾积水,3周后拔管有2例肾积水,均有两例泌尿器感染,2周后拔除肾造瘘支架管23例,有2例发热。其中1例为上呼吸道感染所致,1例在放置引流管后1个月痊愈,3周后拔除内支架管25例,1例发热,放置引流管术后3周后痊愈。结论放置肾造瘘支架管2周或3周无区别,都能达到手术要求。
