It seems as though most of the posts regarding your question are leaning toward cautioning you away from a hysterectomy. There are so many factors, obviously...what are the pros and cons for you? I tend to side with the philosophy of "less is more" when it comes to major surgery, and have the least invasive, least complicated surgery that you can, to relieve your symptoms and improve the quality of life.
My mother had a hysterectomy, and the doctor "nicked" her bladder during the operation. She has had bladder problems ever since (they are improving, though), but how frustrating (and scary) that she needed bladder surgery after her hysterectomy. This happens rarely (or, so I read!), but it is important to know the full spectrum of risks and benefits...that will help you make your decision.
