I had bladder stones removed Monday and my doctor told my parents that my bladder is not emptying fully which is what is causing the stones to form. I did not get to talk to the doctor after this procedure and didn't even know this until my dad told me today. What can I do about this to make sure that my bladder empties completely. I use a foley and drain into a leg bag. I have a lot of mucus in my urine and there are times when there is nothing in the bag so I have suction it out. I can tell that their is more mucus when I don't get enough water. My urine also seems more thicker when I don't drink enough. I am working on making sure I get at least 90 oz. of water a day but that doesn't always happen like when I'm out somewhere.
