PHILADELPHIA - Each year, more than a half-million Americans go to the emergency room for kidney stones. Severe pain, bloody urine, and vomiting are just three of the awful symptoms, but even worse, they're increasing in children.

"The rate is increasing at about five percent per year, so it's a dramatic increase," shared Dr. Gregory Tasian, an attending urologist at Children's Hospital of Philadelphia.

And those who have stones have a 50% risk of developing another one within five to seven years. Risk factors for kids include being overweight, being dehydrated, and being prescribed unnecessary antibiotics.

"Right now, we know that there's these five antibiotics that are associated with kidney stones, mainly cephalosporins... broad spectrum penicillin's, which is something like Augmentin," Tasian continued.

Risk also increases during temperature extremes, so make sure your child drinks extra fluids in the heat of the summer and cold of winter.

The National Heart, Lung, and Blood Institute suggests putting your child on the "dash diet" to decrease the risk of developing stones.

Small kidney stones may pass at home with extra fluids. For others, you may need medication or shock wave therapy to break up the stone, or a ureteroscopy, but you should not wait longer than six weeks if trying to pass it on your own.
