Kidney Stones Overview. Kidney stones are small pebbles of salt and mineral in the urine. The most common symptom is severe pain. Most stones pass on their own, but medical procedures are used to remove some kidney stones.
Kidney Stones are crystal aggregations of dissolved minerals in urine that usually form inside the kidneys or the bladder. These stones can often be successfully dissolved using inexpensive kidney stone remedies found at your local supermarket. This can be a painful condition when stones are present in the kidney or bladder but especially when passing a kidney stone with the mineral accumulation lodged in the ureter.
