We compared transvaginal sonography, sonohysterography, and diagnostic hysteroscopy in the evaluation of abnormal uterine bleeding, Sixty-eight women 40 or older with abnormal uterine bleeding were assigned to undergo either transvaginal sonography or sonohysterography. All subjects then had diagnostic hysteroscopy and endometrial biopsy. Patients with abnormal findings underwent operative hysteroscopy or definitive therapy. Transvaginal sonography, sonohysterography, and diagnostic hysteroscopy revealed a sensitivity of 95%, 90%, and 78%, and a specificity of 65%, 83%, and 54%, respectively. The average cost for transvaginal sonography of sonohysterography was $195 and the cost for diagnostic hysteroscopy was $675. Transvaginal sonography and sonohysterography are cost-effective alternatives and more sensitive diagnostic tests than office diagnostic hysteroscopy.
