LadyTay-- same experience with blockage dispersing due to the contrast agent. i prefer to get home to empty, but finally convinced myself that nobody knows what the catheter is for so why worry. and of course, same experience with doctors not dealing with k pouches. doctors and nurses are interested in looking at it, but just look not learn.
amos--had additional thought on empty/irrigation routine. (btw, good to hear you are willing to try this.) this might not be the solution for your problem, although it is a good technique to minimize bacteria lingering in the pouch and subsequently pouchitis.
trying different things can help during your doctor's appointment. you can explain the results of the routine, along with your diet and other changes that you made. all this provides the doctor more information to diagnose. you know your body better than any doctor can so provide them info on it.
keep us posted! be well, jan
