[The ultrastructural changes occurring in the endometrium of women who use intrauterine pessaries].
The authors studied ultrastructural changes in the endometrium of 25 women, using intrauterine contraceptive devices, preventing conception, during various time limits. The material of the endometrial biopsy was fixed with glutar and osmium in a phosphate buffer and embedded in durcopan. Section were prepared by a microtome and observed under electron microscope of Hitachi type. Comparing the parameters duration of usage of loops and character of changes in the endometrium an impression was obtained that the usage of contraceptive intrauterine devices for one-year period did not induced changes of pathological character. Functional changes in the endometrium occurred after a two-year stay of the loop in the uterus as there were inflammatory changes of spot-like character in two of the sections. Local areas of inflammation of nonspecific character, manifested under the form of lymphocytes and leucocyte accumulation, were found in women with long usage of contraceptive intrauterine devices. The authors advise to remove the loop 2.5-3 years after its application and to wait for the complete regeneration of the endometrium.
