What is a kidney stone? From its name people have misconception of having actual stone in the kidney. Kidney stone is hard mass which gets developed in kidney from the crystals which separate from urine within urinary tract. Urine has chemicals that work to prevent inhibition of crystals formation. For some people these inhibitors don’t work and so there is formation of stones in kidney. If the size of stone is tiny then it passes through urinary tract and passes out of body with the urine. Kidney stone contain various combination of the chemicals. Common type of stone contains calcium with combination of oxalates or phosphates. The oxalates and phosphates are part of normal diet of people and are needed in body for bones and muscles. Other stones are struvite which are infection stone caused due to infection in the urinary tract. Other kidney stone types are uric acid stones, and rare cysteine stones.
Remember Gallstones are different stones and are not related to kidney stones at all. They form in different area of body.
