At Mayo Clinic, colorectal surgeons examine the entire pelvis to determine the extent of your rectal prolapse and whether you need surgery. One test that is particularly helpful in diagnosis is:
- Dynamic MRI. This noninvasive test scans the entire pelvis during a bowel movement and produces a video of the pelvic muscles and pelvic organs at work. Dynamic MRI also reveals prolapse in other pelvic organs, such as the bladder or vagina.
