The majority of kidney stones contain a chemical combination of Calcium and Oxalate.
There is no definitive medication for prevention, but drinking plenty of fluids is vital to avoid formation. The daily recommended amount of liquid is 2 litres. Mineral water which contains small amount of minerals is considered suitable and also herbal teas which are sold in local health stores and chemists.
From the colour of urine, it is possible to detect that the requisite amount of liquid has been taken. The colour of urine should be light, transparent yellow almost like water.
4-6% of the kidney stones are made up of uric acid and salt.
To prevent uric acid stones – or sometimes dissolve them - uric acid reducing drugs can help. Alternatively, alkaline medication can be used to reduce the acidity of urine.
