What Is The Suggested Treatment For Dissolving Kidney Stones?

Following excruciating paIn and vomiting, I have undertaken an ultra sound and CT scan defining kidney stones. I do not drink fizzy drinks, alcohol, only one cup of coffee a day, all other liquids being app. 1 ltr. or more of fresh tank water, eat very little meat, drink very small quantity of skim milk (only in cup of coffee) and other dairy, however, have app 2 tablespoons of natural yoghurt daily. My diet intake consists of homegrown fruit and vegetables, maybe one to two slices of toasted whole-meal/whole-grain or rye bread, perhaps an egg or two, no fast-food, no takeaway, no cakes, biscuits, sweets. Moderate intake of spinach and tomatoes. What would you suggest to dissolve the stones and prevent reoccurrence? Thank you
