There are several types of stoma, depending on the procedure used to create them:
Colostomy: A stoma is created with part of your colon, also known as your large intestine, to bypass your rectum. In some cases, you might have the lower part of your colon removed, leading to a permanent stoma. A colostomy can also be temporary if your colon just needs to heal. You might need a colostomy if you have colon or rectal cancer, a colon injury, or a blockage in your colon.
Urostomy: Your doctor will make a pouch using your small intestine. They’ll connect your ureters to this pouch so that urine can drain outside of your body without passing through your bladder. You might need a urostomy if your bladder is diseased or damaged.
Ileostomy: A stoma is created using your small intestine so waste can bypass your colon and rectum. This is the most common type of temporary stoma, but they can also be permanent. You may need an ileostomy if you have Crohn’s disease, ulcerative colitis, or bowel cancer.
