Abstract
To compare the diagnostic accuracy of three dimensional sonohysterography versus hysteroscopy in the evaluation of the uterine cavity in cases of premenopausal bleeding with suspected intracavitary lesions with correlation to the histopathological findings, and to see if (3D - SHG) is superior or comparable to hysteroscopy in the diagnosis of these lesions. 50 women with premenopausal bleeding with suspected intracavitary lesions either by 2D transvaginal ultrasound or by hysterosalpingography were subjected to three dimensional saline infusion sonohysterography, office hysteroscopy and subsequent surgical procedures (fractional curettage, hysterectomy, polypectomy or myomectomy) followed by histopathological examination of the specimens. Three dimensional saline infusion sonohysterography is comparable to diagnostic hysteroscopy in diagnosis of intracavitary lesions, the sensitivity, specificity, PPV, NPV and overall accuracy were; 97.83%, 100%, 100%, 80% and 98% respectively for (3D - SIS), and 100%, 100%, 100%, 100% and 100% respectively for (OH
