Objective: The principal objective was to compare the diagnostic accuracy of two-dimensional transvaginal ultrasonography (2D TVUS), three-dimensional transvaginal ultrasonography (3D TVUS), and hysteroscopy with histopathology in patients with abnormal uterine bleeding. Materials and Methods: Fifty patients were included and underwent the three imaging methods. The negative predictive value, positive predictive value, sensitivity, and specificity of the methods were calculated. Determination of endometrial pathology and endometrial polyps by measuring the endometrial thickness, volume, and uterine area was examined. Results: The complaint of menorrhagia was reported by 72.0% of participants. Histopathologically, 70.0% of the patients had endometrial polyps and leiomyoma being monitored. An endometrial polyp was detected in 58.0% of the patients by 2D TVUS, 80.0% by 3D TVUS, and 68.0% by hysteroscopy. While 2D TVUS demonstrated 65.71% accuracy in the detection of an endometrial polyp, 3D TVUS had an 80.0% accuracy, and hysteroscopy had a 77.77% accuracy. An endometrial polyp was detected when the uterine area was ≥237 mm2. If the endometrial thickness was over 10.5 mm, it was found to be related to an endometrial polyp. According to the volume measurements by 3D TVUS, the detection of an endometrial polyp was made with 96.4% sensitivity, provided that the pathology volume was ≥0.082 cm3. Conclusion: In this cohort of patients, 3D TVUS achieved a high sensitivity to detect abnormalities and could be considered as an initial diagnostic modality, prior to the surgery, and may rival invasive procedures, such as hysteroscopy.
