Hello Sir, You will have to understand that formation of kidney stones is a tendency of your body and that you too take same diet like rest of your family but they donot have stones and you have them is cause your body is different from them. To solve the problem once and for all you need to visit/consult a good homoeopathic clinic which will not only stop the formation of kidney stones but also help in getting rid of stones that are there. Also there is no such specific medicine that will stop this tendency. It depends upon patient what medicine he/she needs
