Overview
Common causes of rectal prolapse include rectal denervation, perineal nerve injury, kinking of the redundant loop of sigmoid colon and loss of rectal compliance.
Causes
Causes of rectal prolapse include:[1][2]
- Rectal denervation
- Perineal nerve injury (due to descent of the pelvic floor, viginal delivery and excessive straining during defection)
- Kinking of the redundant loop of sigmoid colon at the junction between the sigmoid colon and the rectum
- Loss of rectal compliance as a result of mesh placement
- Altered colonic motility
- Anismus (paradoxical contractions of the pelvic floor and obstructive symptoms)[3][4]
