Clinical and diagnostic evidence of benign endometrial pathology in postmenopausal patients

The objective: to study clinical and diagnostic features of the benign endometrial conditions in the postmenopausal women.Materials and method. 64 postmenopausal patients with various severity of postmenopausal vaginal bleeding were examined. All patients underwent clinical, radiological, laboratory and histological examinations, reproductive history data and body mass index indicators were evaluated. Of them 33 persons were diagnosed with complex endometrial hyperplasia without atypia, 16 women – endometrial polyp and 15 women – hyperplasia with atypia. Routine gynecological examination including abdominal and pelvic examination following transvaginal ultrasound examination for the determination of the uterine and ovarian volume as well, as the endometrial thickness were conducted. Patients included in the study underwent computer tomography and magnetic resonance imaging as indicated. All patients with endometrial pathology underwent endometrial biopsy by standard dilatation and curettage or Pipelle-biopsy with histological examination of the obtained material. The concentrations of follicle-stimulating hormone (FSH), luteinizing hormone (LH), dehydroepiandrosterone sulfate (DHEA-S), estradiol, estrone, progesterone, prolactin, and testosterone were determined in blood serum.Results. It was confirmed that in 87,5% of cases endometrial hyperplasia manifested with vaginal bleeding. Endometrial thickness in examined persons ranged from 14.1±1.6 mm in patients with atypical endometrial hyperplasia to 21.3±4.8 mm in patients with complex endometrial hyperplasia without atypia. The study of blood levels of hormones found that postmenopausal patients with endometrial hyperplasia have lower FSH concentration, LH/FSH ratio, estradiol, testosterone levels, with significantly high values of prolactin, DHEA-S and estrone. During the postmenopausal period, hyperplasia was developed in 10% of cases by the presence of bleeding, and 86.2% of cases by the presence of blood spotting. Conclusions. The study suggests that high body mass index, numerous artificial abortions, high blood levels of estrone, DHEA-S and prolactin as well as increased thickness of endometrium influence the frequency of endometrial hyperplasia in postmenopausal women.
