Greetings, Kristimiler29: Welcome to the kidney disorder healthboards!
I suppose it depends on how big the stones are. Some stones are the size of a grain of sand and pass within a few days to a week others are so big they fill the pelvis of the kidney and never come out. Some people drink freshly juiced apple juice and lemon and soften them to the point they dissolve out. Some good foods might also include the hazelnut, grapes, asparagus, red mombin (anti-spasmodic and helps with pain), green bean cauliflower, pear, watermelon, peaches, borage, eggplant, celery, and artichoke.
Others find they need to have them broken with a special machine which is sometimes not so healthy for the kidney or maybe a surgery to have it out I suppose. The smaller ones of 1 mm might dissolve with juices and certain foods. I am not sure how big the juices can dissolve stones for the bigger ones. Even a stone 1 mm big can cause a great deal of pain I sympathize.
I would avoid calcium supplements and vitamins containing minerals and stay away from chocolate. Other things I would reduce or avoid completely include too much protein large amounts of beans, large amounts of nuts, large amounts of grains, dairy products, cheese, meat, alcohol, vitamin C supplement, green leafy vegetables, sour dock, things containing oxalic acid such as spinach and swiss chard containing coffee, beer, and salt. Of course everyone makes their own health choices and is in charge of their own healthcare. Peace,
