According to a 2007 study doctors at North Shore-Long Island Jewish Medical Center has had a fivefold increase in children with kidney stones between 1994 and 2005. The study was published in the Journal of Urology.
Loyola University Medical Center in Maywood, Ill. doctor David Hatch has had a eight-month-old female patient whose mother found a pea-size kidney stone in her diaper.
While doctors are not completely sure what is causing the increase in children they are speculating that diets with too much salt is a leading problem. Excessive salt can bring forth excessive calcium in urine. As most kidney stones with children are calcium-based eating habits and not enough water is putting them at risk.
While most kidney stones main symptom is extreme pain there is the chance for kidney damage if urine flow is blocked by the stone.
Drinking plenty of water is one key way to avoid kidney stones. Children who have already had a stone are told to drink citrus juice like lemonade to help keep urine from forming new stones.
