A stoma is an artificial opening in the bowel that can be temporary or permanent. The new outlet created is through a surgical opening onto the abdominal wall.
There are three different types of stomas:
Colostomy – solid faecal output.
Ileostomy - soft faecal output.
Urostomy (Ileal Conduit) - urine output.
A colostomy or ileostomy can be temporary or permanent. A urostomy is always permanent.
