Abstract To investigate the value of transvaginal ultrasound (TVS) combined with hysteroscopy (HS) for diagnosing postmenopausal uterine bleeding. Methods: 177 patients with postmenopausal uterine bleeding were selected as the research objects, all of them were examined by TVS and HS. The results of hysteroscopic biopsy or surgical pathology were taken as the gold standard to compare the diagnostic efficacy of TVS, HS and their combined diagnosing endometrial diseases. Results: The sensitivity (95.8%), the specificity (95.5%), and the negative predictive value (91.5%) of combined TVS and HS were significant higher than those of TVS or HS alone (all P＜0.05). The diagnostic coincidence rate of endometrial cancer (94.4%), endometrial hyperplasia (96.2%) and endometritis (95.2%) of combined diagnosis were significantly higher than that those of TVS or HS alone (all P＜0.05). Conclusion: TVS is the primary choice for screening postmenopausal uterine bleeding. If the diagnosis result is positive or the clinical symptoms of patient without positive result still persists, it should be examined by HS combined with biopsy and histopathology of the endometrial lesion, in order to find endometrial cancer and precancerous lesions in time.
