目的 探讨国产TCu2 2 0c宫内节育器 (IUD)放置 15年左右 (1317年 )子宫内膜的形态学改变及其安全性 ,并为临床放置年限提供科学依据。方法 采用光镜、透射电镜 ,从组织病理学和超微结构病理学角度 ,对2 4例放置国产TCu2 2 0cIUD15年左右妇女的子宫内膜进行形态学研究。结果 TCu2 2 0cIUD放置 15年左右 ,铜离子的作用在逐渐减弱 ,对子宫内膜的影响也在逐渐减轻 ,但TCu2 2 0cIUD仍然具有抗生育作用。子宫内膜没有癌变倾向。对进入更年期的妇女 ,放置TCu2 2 0cIUD15年左右 ,子宫内膜仍无间变和癌变。结论 TCu2 2 0cIUD放置 15年左右是较为安全的。
Objective To investigate the morphological changes and safety of the endometrium placed in the domestic TCu2 2 0c intrauterine device (IUD) for about 15 years (1317), and to provide a scientific basis for clinical placement. Methods Twenty-four cases of domestic uterine rupture caused by TCu220cIUD were treated with light microscopy and transmission electron microscopy in histopathology and ultrastructural pathology. Results TCu2 2 0cIUD placed about 15 years, the role of copper ions gradually weakened, the impact on the endometrium also gradually reduced, but TCu2 20cIUD still has anti-fertility. Endometrium cancer-free tendency. For women entering menopause, placed TCu220cIUD for 15 years, the endometrium is still no change and cancer. Conclusion TCu2 20cIUD placed 15 years is more secure.
