Kidney Stones

Kidney stones are hard masses that form in the urinary tract from crystals that have separated from the urine. The most common type of kidney stone is formed from calcium, but other types include a struvite stone or uric acid stone, according to the National Kidney and Urologic Diseases Information Clearinghouse. The exact cause of kidney stones is unknown, but those with certain genetic disorders, kidney disorders and recurrent urinary tract infections are more likely to develop kidney stones. Symptoms of kidney stones include extreme pain, cramping in the back and lower abdomen, nausea and vomiting. Most kidney stones can be passed by increasing daily fluid intake to two to three quarts of water per day. If stones are too large to pass with an increase in water consumption, surgery may be needed to break the stones.
