Kidney stones are hard deposits of minerals, usually calcium-based compounds, that lodge in the urinary tract. They are painful, though not deadly, and pretty common in adults — about 11% of men and 6% of women in the United States have kidney stones at least once during their lifetime, according to the National Institutes of Health.
However, a troubling new trend has surfaced. "Historically, stones were pretty much a disease of white, middle-aged men, but that's changed dramatically over the last 30 years," Gregory E. Tasian, a pediatric urologist at Children's Hospital of Philadelphia, told The Washington Post. Children are now making up a larger portion of kidney stone diagnoses, with a "10% increase every year over the last decade or so," indicating an "epidemiologic rise," said Kate Kraft, a pediatric urologist at the University of Michigan Health C.S. Mott Children's Hospital.
While genetics can play a part in whether someone will get kidney stones, diet and lifestyle have a large role — and high-sodium diets are a key culprit. "There is so much added salt to the American diet today, and when the kidney is excreting the sodium, it pulls calcium with it and increases the risk of calcium-based stones," John S. Wiener, a pediatric urologist at Duke Health, said to the Post. "Any child with kidney stones should be referred to a pediatric nephrologist or urologist with expertise in kidney stone disease," said David J. Sas, a pediatric nephrologist at Mayo Clinic in Rochester, Minnesota. |
