Kidney stones on the rise among kids

Kids at increased risk for kidney stones

LOUISVILLE, KY (WAVE) – Kidney stones were once considered mostly something adults had to deal with but, now doctors say they are showing up in children more than ever.

Kidney stones, hard deposits made of minerals and salts that form inside the kidneys, can affect any part of the urinary tract and often are incredibly painful to pass. According to researchers, cases of children and teens with kidney stones have increased steadily over the past two decades.

"Our practice sees multiple kids a month for kidney stones," Norton Children's Urology Dr. Eran Rosenberg, said. "The numbers are growing each year."
Different studies mention different ages and gender groups, so it is hard to pinpoint a specific group at risk. But for why more kids are developing kidney stones, Dr. Rosenberg points to the evolution of the sodium-filled American diet.

"The chances of developing kidney stones increase when children eat more salt," Dr. Rosenberg said. "Excess salt has to be excreted through the kidneys, but salt binds to calcium on its way out, creating a greater concentration of calcium in the urine and the kidneys."

Dr. Rosenberg, who currently is conducting his own research on how to better diagnose kidney stones, said some people fall victim to genetics.

The best way to prevent kidney stones is drinking water and limiting salt.

"We see more kids with kidney stones in the summer because they're more likely to become dehydrated," Dr. Rosenberg said. "Water helps flush out the system and keeps those deposits from building up."

A kidney stone may cause the following symptoms:

•    Severe pain in the side and back, below the ribs
•    Pain that radiates to the lower abdomen and groin
•    Pain that comes in waves and fluctuates in intensity

•    Persistent need to urinate
•    Urinating more often than usual

•    Urinating small amounts

Seek immediate medical attention if your child experiences the following:

•    Pain so severe that he or she can't sit still or find a comfortable position

•    Pain accompanied by fever and chills
