Empty it and rinse again, if you like. You may want to rinse the pouch many times to clean it, but you do not need to rinse it each time you empty it. If you use a pouch deodorant, put some into the pouch after you've finished rinsing it. Put the clamp back onto the pouch to close it. Wash your hands with soap and water.
Some people prefer an opaque white or beige pouch to a clear one.
Your ETN or doctor can help you decide which type is best for you. When you change your pouch, check the stoma and the skin around it. Because it has many small blood vessels, it may bleed when you clean and wipe it. Do not worry about the bleeding unless it fails to stop. The stoma may get smaller during the first weeks after surgery.
