What is (are) Kidney Stones in Children ?
Four major types of kidney stones occur in children:
                
- Calcium stones are the most common type of kidney stone and occur in two major forms: calcium oxalate and calcium phosphate. Calcium oxalate stones are more common. Calcium oxalate stone formation has various causes, which may include high calcium excretion, high oxalate excretion, or acidic urine. Calcium phosphate stones are caused by alkaline urine.  - Uric acid stones form when the urine is persistently acidic. A diet rich in purinessubstances found in animal proteins such as meats, fish, and shellfishmay cause uric acid. If uric acid becomes concentrated in the urine, it can settle and form a stone by itself or along with calcium.  - Struvite stones result from kidney infections. Eliminating infected stones from the urinary tract and staying infectionfree can prevent more struvite stones.  - Cystine stones result from a genetic disorder that causes cystine to leak through the kidneys and into the urine in high concentration, forming crystals that tend to accumulate into stones.
