Renal stones are one of the important problems in India especially rural India.The soft water is used in most of the urban centres and in rural areas, the bore well , well, ponds and lakes are the sources of water. Mostly,the water is hard water and contains more minerals responsible for formation of renal stones. My experience is by boiling water from well and other sources of hard water, the minerals will get sedimented and the water which can be filtered will not produce stones. As an example a family which boils water and use it was not affected by stones.
In the same locality, another family which was using the water not boiled,two members of the family developed stones and undergone tests and treatment. So, a simple advice to all the citizens of India is boil water of any source and you can avoid stones of renal system. "Boil water and prevent renal stones"
