Nanners, I have had calcium stones also but mostly I have uric acid stones. I was taken off allopurinal when I was put on Imuran. You cant take them together. I started passing the uric acid stones one or two per month. Finally told doc enough is enough and was taken off Imuran , put on Methotrexate and back on allopurinal. So far so good. It helps with the uric acid levels. I also watch what I eat. Some things are high in purines,( a major cause of high uric acid levels) turkey, liver, sweet peas, gravy,,,its a long list. I try to avoid them but being Diabetic adds to the , what can I eat equation, thus the med. I think my diet is pretty simple . If it taste good, spit it out, I cant have it. Now sticking to this diet, thats the hard part. And yes drinking lots of water is a help, but even drinking so much water that my eyes were floating did not save me from the ER visits.
If we would read the secret history of our enemies,we would find in each mans life sorrow and suffering enough to disarm all hostility.
