More Kids Getting Kidney Stones
Sept. 19 -- THURSDAY, Sept. 18 (HealthDay News) -- When you think of kidney stones, kids don't usually pop to mind. But doctors say they're seeing increasing numbers of children with the painful condition, and it could represent more fallout from the obesity epidemic.
While exact numbers of children with kidney stones are elusive, physicians at children's clinics say the numbers are up. "There is very little available on pediatric stone disease in particular," said Dr. Caleb Nelson, a urologist at Children's Hospital Boston. "Most data has looked at adults or the entire population."
Still, Nelson and other experts are certain there are more kids with kidney stones, despite hard numbers.
"Proposed reasons include sedentary lifestyle, obesity increase, processed high-salt diets," Nelson said. Some children get the stones, because birth defects in the urinary tract put them at risk for urinary obstruction. "Another subset of children is premature infants who form stones related to the medications they require," he said.
Physicians at the Johns Hopkins Children's Center in Baltimore say they, too, are seeing more children with kidney stones. Dr. Alicia Neu, a kidney specialist at the Children's Center, said that, while it's unexpected, it's not really surprising, considering that other conditions related to poor diet -- such as obesity and type 2 diabetes -- are also on the rise.
A kidney stone is a hard mass that results when calcium oxalate or other urinary chemicals form sticky crystals. The crystals grow and become stones that can range in size from a grain of sand to a golf ball, according to the National Kidney Foundation.
About 90 percent of kidney stones pass through the urinary tract by themselves within about six weeks with medication, better diet and an increased intake of fluids. But, some need to be removed using procedures such as shock wave lithotripsy, in which high energy shock waves administered from outside the body break the stones into fragments.
