Comparative study between three-dimensional transvaginal ultrasound and hysteroscopy in evaluating uterine abnormalities among infertile women

Background Objectives were to assess the diagnostic accuracy of three-dimensional transvaginal ultrasound (3D TVUS) compared to hysteroscopy in detecting uterine cavity abnormalities in infertile women.

Methods This prospective study included 67 infertile women who underwent both 3D TVUS and hysteroscopy. The findings from both modalities were compared to evaluate their concordance and diagnostic performance.

Results Of the 67 patients, 29 (43.3%) exhibited a normal uterine cavity on both 3D TVUS and hysteroscopy. Among the 38 patients with uterine abnormalities, the distribution was as follows: polypoidal endometrium: 3 patients, submucosal fibroids: 9 patients, endometrial polyps: 15 patients, uterine septum: 6 patients, intrauterine adhesions: 3 patients and endometrial hyperplasia: 2 patients. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 3D TVUS for detecting uterine abnormalities were calculated, with hysteroscopy serving as the gold standard.

Conclusions 3D TVUS demonstrated high diagnostic accuracy in detecting uterine cavity abnormalities and showed substantial agreement with hysteroscopy findings. Given its non-invasive nature, 3D TVUS can be considered a reliable initial screening tool for evaluating uterine abnormalities in infertile women.
