A continent ostomy catheter is designed for people who have a special type of ileostomy called a continent ileostomy. This kind of ostomy is an internal pouch that is made from part of the small intestine. The pouch is made via a valve created by a surgeon, which stays inside of the body. It serves as an alternative to an ostomy bag that is worn on the outside of the abdomen. In order to drain the internal pouch, you will need to use a continent ostomy catheter. This straight catheter is inserted into the stoma to expel output. A continent ostomy should be drained every few hours while you are awake, and first thing in the morning after a night of sleep.
