kidney stones are formed when small mineral sediments accumulate in your kidneys for an extended period of time .
These mineral sediments that form the stones usually consist of uric acid or calcium, an insoluble compound that is present in urine .
Kidney stones are more common in children and adolescents.
The problem arises when the body has excess oxalate, a plant compound found in some foods.
Lemon juice decreases the acidity of urine; this prevents the formation of calcium oxalate and uric acid stones.
