It does sound like it would be the best solution. I can see what the doctor means. If they leave the ovaries, at least you wouldn't experience surgical menopause, which can be a bit brutal. But you would say goodbye to your womb. How do you feel about that? It might be a good idea, for the sake of your general health.
Fibroids naturally shrink after
menopause, and often cause no more trouble, but with the kidney involvement, I would say it's best to have the surgery.
