hello and welcome, I understand your problem. It would be an immense help if the indication for the hysterectomy is known. However as of now, the cause may be local in the vagina and not in the pelvic cavity. So a CT may not pick it up. You must visit a skilled gynecologist and have a per speculum examination. Local causes include vaginal polyps [ non cancerous tumors of vagina], atrophic vaginitis [ due to low estrogen] and stumps of cervix that is sometimes left behind during surgery. Other rare causes are a vaginal vault cancer. It is rare and usually causes post coital bleeding and foul discharge. So please see a doctor and get examined. Hope this satisfies your query. Thanks for using HCM. Feel free to ask any more questions that you may have. Dr Madhuri Bagde Consultant Obstetrician and Gynecologist
