The middle rectal valve is one of the three transverse folds within the rectum, an integral part of the digestive system. When this valve slips out of its usual position, it’s known as middle rectal valve prolapse. While this is less common than full rectal prolapse, it can cause discomfort and impact bowel movements.
Anatomy of the Middle Rectal Valve
The middle rectal valve, also called Houston’s Valve, is one of three transverse folds within the rectum:
- Structure: These valves are made of rectal mucosa and submucosa and help control stool movement within the rectum.
- Blood Supply: The rectum receives its blood supply from three primary arteries: the superior rectal artery, middle rectal artery, and inferior rectal artery.
- Nerve Supply: The rectum’s nerve supply involves the pelvic splanchnic nerves, which are crucial for rectal sensation and function.
Types of Middle Rectal Valve Prolapse
- Internal Prolapse: The valve remains inside but collapses inward, causing obstruction.
- External Prolapse: The prolapse extends outside the anal opening, visible externally.
Causes of Middle Rectal Valve Prolapse

- Proctoscopy – Visual examination of the rectum.
- Sigmoidoscopy – Views the lower colon.
- Colonoscopy – Examines the entire colon.
- Anorectal manometry – Measures rectal function.
- Defecography – X-ray of rectal emptying.
- MRI Defecography – MRI to view pelvic muscles.
- Ultrasound – Assesses rectal wall thickness.
- CT Scan – Provides a detailed rectal image.
- Balloon expulsion test – Measures anal function.

- Rectal biopsy – Evaluates tissue for damage.
- Anal ultrasound – Detailed view of the anal canal.
- Pelvic floor stress test – Measures muscle strength.
- Barium enema – Highlights the rectal shape.
- Pelvic MRI – Assesses overall pelvic structures.
- Stool tests – Identifies infections or inflammation.
- Anorectal ultrasound – Checks for sphincter defects.
- Urine analysis – Rules out related urinary issues.
