The catheter is a simple hollow plastic tube. It is inserted about 5 inches into the stoma, and the contents of the reservoir come out on their own. Immediately after surgery the pouch is emptied about every three hours, because the reservoir is small. But following the surgery it grows in size until it can be emptied only 3 or 4 times a day, approximately 2 months after surgery. In the absence of late night meals, it is rare to have to get up at night to empty. This is in contrast to some of the alternative surgeries such as the J pouch, where night time emptyings are generally necessary. In between emptyings, the stoma is covered with a piece of gauze to absorb the mucus coming from it. The stoma is typically about 1/2 inch in diameter.
Kock pouches are not used to replace colostomies.

Another complication is pouchitis, an inflammation of the mucous membrane of the pouch. Symptoms include loose stools and sometimes bleeding. Pouchitis is treated with antibiotics, and the symptoms usually disappear within a week.
