Abstract: Objective: To investigate the causes of vaginal bleeding after menopause in the elderly.Methods: The clinical data of 113 elderly women with vaginal bleeding were analyzed retrospectively.Results: Among the 113 cases,78 cases were benign lesions,of which 52 were cervicitis,10 endometritis,7 uterine leiomyoma,7 endometrial hyperplasia and 2 ovarian cysts;32 cases were malignant tumors,of which 19 were cervical cancer,10 endometrial cancer,2 ovarian cancer cases and 1 case was fallopian tube cancer;3 cases were precancerous lesions.Sixty-two cases of vaginal bleeding were caused by inflammation.The incidence of malignant tumors was 44.00% in the group over 70 years of age,while it was only 23.86% in the group under 70.The difference was significant between the two groups(P<0.05).Conclusions: The main cause of vaginal bleeding in the elderly after menopause is gynecological inflammation,and the next is cancer.Knowledge of the causes is beneficial to early diagnosis and treatment.
