Intra-uterine fluid collection in postmenopuasal women with cervical stenosis

The aim of the study was to assess the clinical significance of intra-uterine fluid collection in postmenopausal women with cervical stenosis with and without vaginal bleeding. A group of 82 consecutive postmenopausal women with cervical stenosis and sonographically confirmed intra-uterine fluid collection underwent D&C with or without hysteroscopy. Diagnostic hysteroscopy was performed in all patients with an endometrial thickness (ET) was greater than 8 mm, or with irregular endometrium at any degree of ET. The patients were divided and evaluated prospectively into two groups according to the presence or absence of postmenopausal bleeding (PMB). Twenty-six women were with PMB and 56 women were asymptomatic. The groups were similar as far as endometrial thickness and histopathological results were concerned. Atrophic endometrium was found in 69 patients (84%), 23 in the PMB group (89%) and 46 in the other group (82%), proliferative endometrium in 7 (9%) and endometrial polyps were found in 35 patients (43%), 12 in the PMB group (46%) and 23 in the other group (41%). When ET was ≥8 mm, in 93% of the cases an endometrial polyp was found (25 out of 27). No case of endometrial cancer was found. A premalignant condition was diagnosed in one patient with an endometrial polyp in the PMB group. All patients with endometrial thickness of less than 3 mm in ultrasound had atrophic endometrium. The incidence of intrauterine pathology increased with the increasing thickness of endometrium as observed by ultrasound. The presence of intra-uterine fluid collection in postmenopausal patients with cervical stenosis seems to be a benign condition. Normal endometrium of less than 3 mm observed by ultrasound in postmenopausal women without vaginal bleeding does not necessarily need further surgical investigation.
