Hello wearingit. Thank you for your post, for although I do not have the problem, it does give me the opportuntity to contemplate what I might attempt to do about it if the occsion was to arise. The first thing that crosses my mind, is that lots hof people with liquid output have commented on similar problems whether they have a flush stoma or a protruding one, so having it altered might not resolve the problem. I would be looking to experiment with some kind of catheta system which would allow the urine to exit without coming into contact with the stoma or the skin. When I was anally irrigating I had a great catheta about the diameter of a pencil, which, once it was on the inside, had a balloon that pumped up and stopped the output from exiting anywhere but through the tube. I've adapted these cathetas for several different experiments and I'm still using one as an aid to to irrigation. It is a pity that there are not manufacturers out there experimenting to make individual lives easier when there are problems like this. Unfortunately, (or fortunately) there are not enough people who suffer, to make it worthwhile financially to continuously experiment, research and develop 'one-off' gadgets. The various things that I have made, has convinced me that most of the the gadgets need to be bespoke to suit the individual concerned and it is not just a question of having a good idea and getting it to work first time. Quite often I have had to tweek the originals many times before it becomes functional and safe. I have had many gadgets that simply do not work, even though the concept was sound. If the manufacturers will not push forward on these things, then I feel it is incumbant upon us to experiment and see what we can come up with that makes our lives easier than they would otherwise be.
I hope you can find a solution to your own problems soon.
Best wishes
Bill
