too early for me but Im not that surprised. in the early days post surgery when I was peeing into a measuring container, I noticed a build-up of a calcium-like deposit in the jug - even though I cleaned it regularly. I wondered at the time that this might be doing the same thing inside my neobladder. hopefully it's not a big problem Pat and that it can be sorted out easily. all the best to you and let us know how you are getting on. I wonder if it's something that cann be helped with diet?
