Three-dimensional ultrasound assessed endometrial morphology and function before and after adnexectomy, finding improved perfusion at 12 months post-surgery, with teratoma patients showing recovery while epithelial tumor patients exhibited thinner endometria.

This study used three-dimensional ultrasound to evaluate endometrial morphology and function in 113 reproductive-age patients before and at 6 and 12 months after unilateral adnexectomy, comparing patients with mature teratomas (n=51) versus epithelial ovarian tumors including endometrioid, serous, and mucinous cystadenomas (n=62). Endometrial thickness, volume, and ultrasound pattern were assessed in the mid-luteal phase, alongside volumetric vascularity indices (VI, FI, VFI), with ovarian reserve evaluated per ESHRE consensus (2022). The authors reported improved endometrial perfusion by 12 months, with compensatory restoration in the teratoma group, whereas an opposite pattern was observed in epithelial tumors—particularly endometriomas, which had an extremely thin endometrium and low glandular layer volume. This paper is centrally about endometriosis — it examines post–unilateral adnexectomy endometrial structure and vascularity differences specifically for ovarian endometriomas.
Abstract
Objective. To study the morphological and functional characteristics of the endometrium in patients of reproductive age before and after unilateral adnexectomy using a three-dimensional (3D) ultrasound imaging. Patients and methods. A total of 113 patients after unilateral adnexectomy were examined. The mean age of patients was 32.85 ± 4.01 years. Two patient groups were identified: group 1 (n = 51) consisted of patients with mature teratomas; group 2 (n = 62) included patients who underwent surgery for epithelial ovarian tumors (endometrioid (30; 48.4%), serous (21; 33.9%), and mucinous (11; 17.7%) cystadenomas). The 3D ultrasound examination of pelvic organs was performed in the middle luteal phase of the menstrual cycle before surgery and at 6, 12 months after it. The endometrial thickness, volume, and ultrasound pattern were studied, as well as volumetric vascularity indices: vascularization index (VI), flow index (FI), and the vascularizationflow index (VFI). Based on the ESHRE consensus (2022), the ovarian reserve was assessed. Results. The improvement of endometrial perfusion was noted at 12 months after surgery. In patients with ovarian teratomas, compensatory restoration of morphological and functional properties of the ovary and endometrium was recorded. The opposite pattern was observed in the group of patients with epithelial tumors. Thus, patients operated on for ovarian endometriomas had an extremely thin endometrium (3.5 ± 0.1 mm), whose values were 1.5 times lower compared to those of patients with serous and mucinous cystadenomas; the glandular layer volume was expectedly low (1.1 ± 0.9 cm3). Conclusion. The minimum effective restoration period for the collateral ovary after unilateral adnexectomy is at least 6 months. The qualitative and quantitative parameters of 3D Doppler velocimetry can be used as predictors of the endometrial morphological and functional state in patients of reproductive age. Key words: 3D ultrasound, mature teratomas, cystadenomas, endometrium, endometrioid cysts, VOCAL
