      This was very interesting information. I have kidney stones, but they are there because my doctor found out that my kidneys are not producing potassium cytrate (sp?)that dissolves stones. She said it is a birth defect. I am now on a supplement for the rest of my life. Both of my kidneys are full of stones, and hopefully I will not have trouble passing them.
