A Feasibility Study for a Randomised Controlled Trial of Pelvic Floor Muscle Training Combined With Vaginal Pessary for Women With Pelvic Organ Prolapse.

It is hypothesised that undertaking PFMT with a pessary in place may increase the level of existing muscle support in the pelvic area: by reducing the descent of the pelvic organs and the consequent stretching of soft tissue the pessary may allow the pelvic floor muscles to be exercised and strengthened more effectively. Potentially this could lead to additional improvements in the pessary retention rate and associated prolapse symptoms beyond that expected from the pessary alone. Urine, bowel and sexual function, which can be affected by prolapse, may also improve independently in response to a PFMT intervention. If a more permanent reduction in prolapse symptoms results from concurrent use of PFMT, this may delay or prevent the need for long term pessary use or surgical intervention. In summary, a PFMT intervention in combination with pessary management for vaginal prolapse may be more effective in reducing symptoms and increasing quality of life than management of the prolapse with a pessary alone. This study will start to provide the evidence to address this question.

This is a feasibility study to develop the methods for a multi-centre RCT. It will run alongside The POPPY Trial (a 17 centre trial of PFMT already underway in the UK; ClinicalTrials Number NCT00476892). Three of The POPPY Trial centres will be involved in this feasibility study. Over a 12 month period, we plan to enrol 50 women with diagnosed prolapse of stage I to IV, who are not eligible for The POPPY Trial because they require a pessary. These women will be randomised into one of two groups: PFMT (delivered by a physiotherapist at 5 appointments over 16 weeks) in conjunction with pessary management of their prolapse or pessary management alone. All women will have a nurse appointment six months after randomisation at which time their pessary will be removed. A replacement pessary will not be immediately re-fitted. At seven months after randomisation all women will have a review appointment with their gynaecologist to have their prolapse assessed, the pessary re-fitted if necessary, and other treatment needs discussed. Women will complete postal questionnaires, at baseline (prior to randomisation), at six months post-randomisation (prior to seeing the nurse to have the pessary removed), and seven months post-randomisation (prior to the 7 month gynaecologist review appointment), and record symptoms in a diary for one month after removal of the pessary. Key outcomes are: prolapse symptoms, prolapse-related quality of life, prolapse severity, and additional prolapse treatment received up to seven months after study entry.
