The easiest way to diagnose a rectal prolapse is through a complete physical examination. Your physician will take a history of your complaints and might be able to visualize the rectal tissue extending through your anus. Unlike hemorrhoids, a rectal prolapse can usually be gently tucked back up inside your rectum. If your doctor has concerns about the severity or underlying cause of your prolapse he or she may send you for further testing.

An evacuation proctogram is a highly specialized radiographic test used to detect and diagnose malformations of your pelvic floor – the area where your rectum lies. This test is not available in all locations due to the specialized equipment needed and is not frequently done for a routine problem.
