输卵管结扎后再通的取舍

绝育术后要求再生育时,可以选择输卵管复通术或者体外受精-胚胎移植(in vitro fertiliza-tion-embryo transfer,IVF-ET)助孕。由于年龄、复通术后输卵管长度、绝育方式及复通术式均会影响复通后妊娠率,所以,<35岁、不合并其他不孕因素的患者更适合输卵管复通术;而>40岁、合并电凝绝育等输卵管复通预后不良因素的患者适合IVF助孕。其他条件的患者,尚无确切证据表明复通术和IVF哪种更有效。

Clinical indications for recanalization following tubal sterilization.

For women planning pregnancy after tubal sterilization，they have to choose tubal recanalization or vitro fertilization（IVF）.The important factors for determining the successful pregnancy after recanalization are the age of patient，the remaining length of tube，the type of sterilization initially performed and the technique of tubal recanalization.For women <35 years who are without other infertility factors，tubal recanalization is suitable，whereas if women >40 years who are with electrocoagulation as the method of sterilization，they are suitable for IVF.Nevertheless，for the rest ones，there is no evidence showing which strategy is likely to be more effective.
