宫内节育器致子宫异常出血与宫内细菌感染的关系

本研究对１４２人的子宫内膜进行厌氧菌。需氧菌培养分离和鉴定。结果表明，置宫内节育器（ＩＵＤ）致出血组细菌感染率为１０．５％（厌氧菌为８．８％，需氧菌为１．７％），显著高于未置ＩＵＤ正常组０％的感染率，Ｐ＜０．０５；并是置ＩＵＤ正常组的３．６倍。置ＩＵＤ出血组厌氧菌单独的感染率也明显高于置ＩＵＤ正常组，未置ＩＵＤ正常组和未置ＩＵＤ出血组。在置ＩＵＤ出血组内，置ＩＵＤ≤１２个月者细菌感染率为２６．３％，而置ＩＵＤ＞１２个月者仅为２．６％．两者比较差异非常显著；并且，带“Ｔ”型ＩＵＤ者细菌感染率是带“Ｏ”型的６倍。

Relationship between abnormal uterus─bleeding associated with intrauterine contraceptive device and intrauterine microbia infection

The endometria of 142 specimens were cultivated in order to detect anaerobia and aer-obia. The microbia were detected in 10.5% of intrauterine contraceptive device(IUD)users with ab-normal uterus bleeding(anaerobia8,aerobia 1.7%).This rate was significantly higher than thatof normal women without IUD and it was 3. 6 times as much as that of normal IUD─users. The in-fection rate of anaerobia alone was significantly higher in IUD─ users with abnormal uterus─bleedingthan those in normal IUD─users,normal women without IUD and bleeding women without IUD. Inaddition,there was a significant difference of microbia infection rates between abnormal uterus─bleed-ing IUD─users using IUD≤12 months and ones using IUD>12 months. The infection rates were26.3%in former and 2.6%in latter. Futhermore,we also found that the microbia infection rate ofKJD─users wore“T”type IUD was six times as nuch as that of IUD─users wore“O”type IUD.
