Most urostomy pouches come as either a 1-piece pouch or 2-piece pouch system.
A 1-piece system is made up of a pouch that has an adhesive or sticky layer on it. This adhesive layer has a hole that fits over the stoma. It can stay on for 1 - 3 days before it needs changing.
A 2-piece pouch system has a skin barrier called a flange. The flange fits over the stoma and sticks to the skin around it. The pouch then fits onto the flange. The flange can stay on the skin for 3 - 5 days before it needs changing.
Both kinds of pouches have a tap or spout to drain the urine. A clip or another device will keep the tap closed when urine is not being drained.
Both types of pouch systems come with either of these:
- Precut holes in a range of sizes to fit different-size stomas
- A starter hole that can be cut to fit the stoma
Right after surgery your stoma will be swollen. Because of this, you or your health care provider must measure your stoma for the first 8 weeks after your surgery. As the swelling lessens, you will need smaller pouch openings for your stoma. These openings should not be more than 1/8 inch wider than your stoma. If the opening is too large, urine is more likely to leak.
Over time, you may want to change the size or type of pouch you use. Weight gain or loss can affect what pouch works best for you. Children who use a urostomy pouch may need a different type as they grow.
Some people find that a belt gives extra support and makes them feel more secure. If you wear a belt, make sure it is not too tight. You should be able to get 2 fingers between the belt and your waist. A belt that is too tight could damage your stoma.
