本文从两个方面讨论IUD和宫外孕的关系。根据4项放置IUD的多中心研究资料(随访5年),其宫外孕的发生率为0.4～1.02/1000妇女年,与国外文献报道相似。惰性金单环和带铜V和T型IUD的宫外孕发生率间无统计学差异;不同时期放置IUD后,以剖腹产时放置者其宫外孕发生率最高,达2.69/1000妇女年。上海市3项对宫外孕患者以1∶2配对对照进行回顾性调查的资料,提示①上海地区使用IUD不增加宫外孕的危险性;②带器妊娠时宫外孕对宫内妊娠之比增加,故对带器者要警惕仍有患宫外孕的可能。两方面的研究表明:IUD使用者与不避孕者相比,宫外孕危险并不增加。
This article discusses the relationship between IUD and ectopic pregnancy from two aspects. According to the 4 multi-center study data of IUD placement (5-year follow-up), the incidence of ectopic pregnancy was 0.4-1.02 per 1000 women years, similar to that reported in foreign literature. There was no significant difference in the incidence of ectopic pregnancy between the Inert gold rings and copper V and T type IUDs. The incidence of ectopic pregnancy was the highest in 2.69 / 1000 women years when placed in caesarean section after IUD placement. Shanghai 3 pairs of ectopic pregnancy patients with a 1: 2 matching control retrospectively survey data, suggesting that ① IUD in Shanghai does not increase the risk of ectopic pregnancy; ② ectopic pregnancy with intrauterine pregnancy increased intrauterine pregnancy ratio, so the band People should be wary of ectopic pregnancy may still have the possibility. Two studies have shown that: IUD users compared with non-contraception, the risk of ectopic pregnancy does not increase.
