I’ve had this issue after having my pouch for 20 years. I had several surgeries to remove distended sections of bowel. I still had problems emptying and the vicious cycle started over again. I just couldn’t empty out. Then I finally had a surgeon willing to work with me and I started to use the catheter and would irrigate out my jpouch. In addition, my surgeon does Botox injections because I had a bit of narrowing down there and it helps relax the muscles. I’ve been doing this for the last 9 years. So depending on what your tests show and what your surgeon is willing to do the catheter can be a God send. Hope this helps!
