Abstract: Objective：To explore the clinical features and pathologic type of postmenopausal vaginal bleeding. Methods: A retrospective analysis was performed from January 1, 2008 to December 31, 2013 at China Medical University Sheng Jing Hospital gynecology wards after a total of 778 cases of postmenopausal bleeding women, each patient underwents pelvic ultrasound, hysteroscopy and surgery and obtain pathology and definitive diagnosis. Results: From 778 cases of patients, endometrial polyps accounts for the highest proportion of 49.23% (383 cases), the second is endometrial cancer 16.71% (130 cases), the third is the submucous myoma 11.44% (89 cases). The most number of cases within 5 years of menopause are postmenopausal vaginal bleeding(311 cases), most of which is endometrial polyps(175 cases), and for menopause more than 21 years, there are the lowest incidence cases (78cases), most of which is endometrial cancer (44 cases). The vaginal bleeding cases are the least (7 cases) for those who are younger than 49, and the most cases (228 cases) for those between 55 to 59 years old, most of which are endometrial polyps. There are 71 patients older than 75 years of age, most of which are endometrial carcinoma(38 cases). In the endometrial thickness, body mass index(BMI), and whether repeated bleeding, endometrial benign and malignant disease has the obvious statistical significance (P＜0.01). Compared with the patients with endometrial benign lesions, endometrial malignant lesions patients own thicker endometrial, greater body mass index (BMI), and are more likely to be repeated bleeding. Conclusions: The main reason caused postmenopausal vaginal bleeding is uterine benign lesions. As the menopause time increasing, endometrial polyps, endometrial hyperplasia and the incidence of submucosal myoma is downward trend on the whole, endometritis, and the incidence of endometrial cancer is on the rise as a whole. With the increase of vaginal bleeding after menopause age, endometrial polyps, endometrial hyperplasia and the incidence of submucosal myoma is downward trend on the whole, endometritis, and the incidence of endometrial cancer is on the rise as a whole.
