Hi Ratwoman,
I will answer what I did for KSR,
I was polycystic, had salpangitis and various other girly problems...I refused the hysterectomy because I was young and still full of hope for kids but my surgeon told me that a hysterectomy would not be a problem for me (a k poucher) because they organize the organs on 'a shelf' in such a way that they all find their spot.
I was worried about things shifting or collapsing but he said that they use mesh or sutures to keep them all in place.
In the end I managed to retain my uterus and ovaries but one never knows...I am no longer scared of losing them (menopaused anyway).
Hope that this answers the question.
