This is for my husband, which has MS and bladder issues. He recently went to a urologist because of wetting at night. Diapers tended to not hold it all, so he was looking for something to stop him from going so much. Particually at night. We found out through the ultrasound procedure that he was not going enough. A spastic spchinter muscle, what starts and stops your voiding, was not releasing and he was "overflowing". In other words, when the bladder got too full, it just let some empty out. He had over 1600 units in his bladder AFTER going to the bathroom. If you don't know how much that is, it is over 1 and a half urinals full. He did not even know it. Turns out this has been going on some time and his bladder was almost 4 times its normal size. Good side of this is a medicine called Flomax. It is suppose to help the spchinter muscle. And he already takes Baclofen. He had stopped it before he knew all of this. Now we have to shrink his bladder back with me catherizing him 3 times a day. Not a great experience, but could be worse. It should be temporary. His bladder, shrunk down, will start getting some message that it is full when it is mildly full.
