Tests and procedures used to diagnose rectal ulcers include:

- Sigmoidoscopy. During this test, your doctor inserts a flexible tube equipped with a lens into your rectum to examine your rectum and part of your colon. If a lesion is found, your doctor may take a tissue sample (biopsy) for laboratory testing.
- Ultrasound. This imaging technique uses sound waves to create pictures. Your doctor may recommend an ultrasound to help differentiate solitary rectal ulcer syndrome from other conditions.
Imaging studies. Your doctor may recommend an imaging procedure, such as defecation proctography. This test allows the doctor to look at your rectum.
During this procedure, your doctor inserts a soft paste made of barium into your rectum. You then pass the barium paste as you would stool. The barium shows up on X-rays and may reveal a prolapse or problems with muscle function and muscle coordination.
Specialized centers may offer magnetic resonance defecography. This test is done on a magnetic resonance imaging (MRI) machine and provides a 3-dimensional image of the rectum.
