Kidney Stone Patient Guide
Painful Mineral Deposits in Urinary Tract
Kidney stones are formed from a combination of minerals and waste materials. The stones may not cause symptoms until they move from the kidneys through the ureters and into the bladder.
Even small kidney stones can cause intense pain until they pass out of the body. Larger stones may lodge in the urinary tract, leading to infection.
Most kidney stones pass on their own over several days, but some are too large and must be broken up with sound waves or be surgically removed. Patients who have kidney stones are at higher risk for future stone formation. Dietary changes and medications can help lower this risk.
Cause Intense Pain Over Several Days Until Passed Out of the Body
Kidney stones are a common urinary tract disorder, accounting for many emergency room visits in the United States each year.
Kidney stones are almost twice as common in men as in women. Age is also important; the risk for men increases after age 40 years, while women are more affected during their 50s. Even children can develop kidney stones; teenage girls have the highest risk.
At any age, a diet high in salt, sugar, and protein increases the risk. Drinking an insufficient amount of water may also contribute to stone formation. Overweight or obese people are at higher risk, as are those with a family or personal history of kidney stones. Certain drugs, as well as diseases of the kidneys, gastrointestinal tract disorders, hyperparathyroidism, and gout, all increase the risk for kidney stone formation.
