【摘要】 本文观察了带不锈钢宫内节育器后引起出血的104例(50.96%的病例带器5年以上)子宫内膜的病理变化,以探讨出血的原因。子宫内膜主要的病理变化为慢性子宫内膜炎(53.85%),子宫内膜增生过长(19.23%),间质充血水肿(13.46%)。104例中40岁以上、带环5年以上的43例与同等条件的非因症取环的36例相对照,结果两组的慢性子宫内膜炎的发生率有显著差异(p<0.01);子宫内膜增生过长和间质充血、水肿的发生率无显著差异,因此认为带器出血可能与慢性子宫内膜炎有关。更多还原

【Abstract】 104 cases of uterine bleeding due to intrauterine devices(IUDs)have bccn observed.At-tempts were made to find out the cause of the uterine bleeding by observing the pathologicalchanges in the endometrium.50% of the cases were over 40 years of age.50.96% of themhad used IUD for more than 5 years.The main pathological changes in the endometriumwere as follows:chronic endometritis(53.9%),endometrial hyperplasia(19.2%)conges-tion and edema in interstitia(13.5%).By way of contrast,the endometrium was examinedin 36 controls,as well as in 48(of the 104 cases)who were over 40 years of age and had usedIUD for more than 5 years.There were significant differences(P<0.01)in the per-centage of chronic endometritis between the group with uterine bleeding(53.48%)andthe control group(11.1%).There were no significant difference(P>0.05)in the per-centage of endometrial hyperplasia and congestion and edema in interstitia between the twogroups.The results obtained in the study suggest that the cause of uterine bleeding due to IUDmay be related to chronic endometritis.更多还原
