Hi ! Good afternoon and a Happy New Year 2014. I am Dr Shareef answering your query. Cervix could be left out in a difficult hysterectomy where it is not possible to go much down due to severe adhesion such as in severe case of endometriosis , although with development of precise operative techniques this situation very rarely arises now. So far as advantage issue is concerned, leaving cervix may give a natural feeling during sex to the partner. The disadvantage is that you have to go for regular pap smears in intervals as a screening procedure to exclude cervical malignancy as in general population. You along with your gynaecologist have to discuss it out to decide what procedure would be best for you. Kegel exercises would not benefit in complete or severe prolapse. I hope this information would help you in discussing with your family physician/treating doctor in planning your treatment. Thanks for using the health care magic forum for your query on health. Wishing you an early recovery. Dr Shareef.
