First of all, you should use distilled water for drinking and also try to use as much fluid as possible which will help in stimulating urine production. Do not use normal water that also contains bacteria that can increase the sedimentation of stone in your kidney.
The use of lemon is another important thing which will help you in passing the stone. Add lemon slices in water or other drinks that you use which will help in breaking the kidney stone in smaller pieces. These small stones will easily pass through your urine.
You can also get rid of kidney stone by doing exercise on a regular basis because it helps in eliminating toxin which is the major reason that creates kidney stone. Exercise also help in passing the kidney stone quicker.
You need to increase the use of citrates as they help in reducing the quantity of calcium in the body. The kidney stone gets bigger in size when calcium builds up in body. If the stone becomes bigger, it will cause trouble and will not pass easily.
When you go to washroom, you should strain urine with a strainer which will help you in checking that whether the small particles of kidney stones are passing or not.
