The American College of Physicians (ACP) tells people who have a history of renal stones how to avoid getting them in future. A fairly common problem affecting almost 7% women and 13% men in the USA at least once during their lifetime, kidney stones can make life unbearable because of pain and other complications. Some stones require medicines, surgical procedures and even sound waves to be expelled from the body. Some kidney stones can cause bleeding and kidney damage in addition to debilitating pain.
Kidney stones are formed when tiny crystals in urine (calcium, phosphorus and other minerals or salts) come together and form hard deposits. If not treated, at least one third of the people who get stones are likely to get them again within the next five years.
