A kidney stone is a solid piece of material that forms in a kidney when substances that are normally found in the urine become highly concentrated. A larger stone may get stuck along the urinary tract and can block the flow of urine, causing severe pain or blood that can be seen in the urine.
Dr. Ari Auron, Pediatric Nephrologist, Blank Children’s Hospital says, "Children with kidney stones may have pain while urinating, see blood in the urine, or feel a sharp pain in the back or lower abdomen. However, children who have small stones that pass easily through the urinary tract may not have symptoms at all."
The treatment for a kidney stone usually depends on its size and composition and whether it is causing pain or obstructing the urinary tract. Children may require pain control and encouragement to drink lots of fluids.
Dr. Auron says, "Increases in obesity rates, less active lifestyles, and diets higher in salt may be causing more children to have kidney stones."
To prevent kidney stones, children should drink plenty of healthy fluids to keep the urine diluted and flush away substances that could form kidney stones.
