I had a kidney stone, it passed on its own. (HUGE relief!) However... I didn't want to reach in and retrieve it (long story) so I don't know what it was made of.

My doc said there are two different materials they can be made of, and the dietary restrictions are radically different for the two. Since I didn't grab mine, she couldn't tell me what foods to avoid and what to eat more of.

Be sure to ask for the lab report on your stones!
