ObjectiveThe aim of the study was to compare the accuracy of 2D saline-infusion sonohysterography (2D-SIS), 3D saline-infusion sonohysterography (3D-SIS), and hysteroscopy in the assessment of intracavitary uterine lesions in women with premenopausal bleeding and determine their correlation with the histopathological diagnosis. We also aimed to follow the treatment plan of each case according to the diagnosis reached.
Study designThe study was prospective in design.
Materials and methodsEighty premenopausal women with abnormal uterine bleeding and suspected intracavitary lesions were subjected to 2D saline sonohysterography, 3D saline sonohysterography, and diagnostic hysteroscopy. They were further managed accordingly. Results 2D-SIS had a sensitivity, specificity, positive predictive value, and negative predictive value of 86.4, 92.3, 88.7, and 91.3%, respectively, when compared with diagnostic hysteroscopy for the diagnosis of intracavitary lesions. In contrast, 3D-SIS had a sensitivity, specificity, positive predictive value, and negative predictive value of 99.3, 98.7, 93.4, and 97.54%, respectively. Conclusion 2D and 3D sonohysterography can accurately diagnose and localize intracavitary lesions almost as accurately as hysteroscopy. 3D-SIS is comparable to hysteroscopy in classifying fibroids according to their degree of protrusion into the uterine cavity and can assess feasibility for hysteroscopic resection, with the advantage of visualizing the intramyometrial portion and identifying associated pathologies. Their accuracy in estimating the protrusion index of fibroids declines as the intramural component increases.
