Evaluation of the Uterine Cavity by 3 D Ultrasonography in Perimenopausal Bleeding in Comparison with Hysteroscopy

Background: Abnormal uterine bleeding (AUB) in perimenopausal women is a frequent but often ambiguously characterized condition that necessitates precise diagnosis. While hysteroscopy remains the definitive method for assessing intrauterine abnormalities, three-dimensional ultrasonography (3D US) has gained attention as a less invasive diagnostic option.
Subjects and Methods: A cross-sectional study was conducted at Suez Hospital, Egypt, and Ain Shams Obstetrics and Gynecology Hospital, Cairo, Egypt. One hundred perimenopausal women presenting with AUB were recruited from the outpatient clinic.
Results: A significant difference was observed between 3D US and hysteroscopic findings (p = 0.018). The sensitivity, specificity, positive predictive value, and negative predictive value of 3D US in diagnosing intrauterine abnormalities were 89%, 54%, 66.4%, and 82.5%, respectively.
Conclusions: Three-dimensional ultrasound serves as a useful diagnostic modality for detecting intrauterine abnormalities in perimenopausal abnormal uterine bleeding. However, cases with negative ultrasound findings warrant confirmation through hysteroscopy, which continues to be the gold standard for precise diagnosis and management of intrauterine lesions.
