Hi Angel...no no...sorry I didn't mean to imply that the calcified stones were hard to get out! Just that, since so many people pass softer stones (that don't show up on ultrasound)...it seems that he'd have an easy time flushing those ones out. People DO get their calcified stones out...they do! You have to be diligent. I think about a month ago I read a woman's post that said that she had an ultra sound before a bunch of flushes and then after...and voila! no stones left! (or maybe only one left...?) So that was very heartening to hear, indeed! I'll try to find that post.
