What are the three main types of ostomies?

The three main types of ostomies are colostomy, ileostomy, and urostomy, which are directly related to the specific part of the gastrointestinal or urinary system that is diverted to the abdominal surface.

A colostomy involves the surgical creation of an opening from the colon to the outside of the body. This type is often performed when a portion of the colon is removed due to conditions such as colorectal cancer, diverticulitis, or trauma.

An ileostomy is similar but involves the small intestine, specifically the ileum. It is commonly used when a person's entire colon has been removed due to conditions like Crohn's disease or ulcerative colitis. The output from an ileostomy tends to be more liquid than that from a colostomy due to the lack of absorption that normally occurs in the colon.

A urostomy is a surgical procedure that creates an opening for urine to exit the body when the bladder is not functioning properly or has been removed, typically due to bladder cancer or severe injury. This diverts urine away from the bladder to an external pouch.

The other options listed relate to different anatomic or functional groupings but do not reflect the standardized classification of ostomies based on their origins within
