Oestrogens for treatment or prevention of pelvic organ prolapse in women

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:

To determine the effects of oestrogen treatment alone, or in conjunction with other treatments, as a preventative measure, or treatment, for pelvic organ prolapse.

The following comparisons will be made:

1. Oestrogen treatment alone versus no treatment/placebo;
2. Oestrogen treatment alone versus another treatment;
3. Oestrogen treatment in conjunction with physical treatment (e.g. pelvic‐floor muscle training) versus physical treatment alone;
4. Oestrogen treatment in conjunction with the use of vaginal pessaries versus the use of vaginal pessaries alone;
5. Oestrogen treatment in conjunction with surgery versus surgery alone.
