Optimal pelvic floor muscle function is known to assist bladder and bowel function and control, pelvic organ support, as well as other areas of health. It is also known that problems in some of tehse areas can be a consequence of pelvic surgery. By addressing the requirements for good bladder and bowel function/control, and organ support in the early post-surgery phase when tissue repair and scar formation are critical, it is proposed that there will be a rduction in the longterm prevalence of bladder problems, bowel difficulties and weakened pelvic floor and abdominal muscles in post-surgery patients. This study is a randomised controlled trial to compare patients undergoing a physiotherapy-supervised pelvic floor muscle training and behavioural therapy program with a control group. It is hypothesised that at the 12 month post-operative follow-up assessment, the treatment group will demonstrate better outcomes in bladder and bowel function and control, as well as stronger pelvic floor muscle contractile strength than the control group.
