Have not been in your position, but do know many who have been. First, you are still at "early days" here and it will take a while to get used to the new normal...which should not include a lot of leaking. You need to find a competent
urostomy nurse who can help you find the right product(s) to use in your individual case. You may not have the best fit for your particular needs. Second, my understanding is that many of the companies who provide urostomy supplies are very generous with samples that you can try. Google and then contact as many companies as you can find, explain your problem, and ask for suggestions.
Best of luck to you
