Also known as renal calculi, kidney stones are hard deposits, which happen when minerals and salts accumulate and cause an obstruction in the kidneys. Several factors contribute to kidney stones, wherein the stones crystallize, become more concentrated, and clump together to form larger stones.
Smaller kidney stones often pass through the urine while the larger ones can cause an obstruction in the ureter or other parts of the renal tract, leading to excruciating pain and discomfort.
