I don't have anything to add, as I've never head of calcification like this, but just wanted to say I live in Maine too (Bangor). I've just been treated by a local urologist, as I've got a very uncomplicated situation with regard to bladder cancer. However, if I were in your shoes I wouldn't hesitate to go out of state to get some answers. Best of luck finding out the source of this and getting rid of it. Is calcification of this type something that happens only in the bladder, or does it occur elsewhere as well?
