Kidney stones have many causes and can affect any part of your urinary tract — from your kidneys to your bladder. Often, stones form when the urine becomes concentrated, allowing minerals to crystallize and stick together


Most kidney stones eventually pass from the kidney through the ureter and bladder and finally through the urethra on their own. However, treatment is often required for pain control from kidney stones as they pass. The consumption of ample fluids helps facilitate the passage of kidney stones, but even with plentiful fluid intake, most people require some type of medications for pain control.


Calcium stones are most common. They are most likely to occur in men between ages 20 - 30. Calcium can combine with other substances to form the stone. Oxalate is the most common of these. Oxalate is present in certain foods such as spinach. It's also found in vitamin C supplements. Diseases of the small intestine increase your risk of these stones.

Renal calculi are formed when the urine is supersaturated with salt and minerals such as calcium oxalate, struvite (ammonium magnesium phosphate), uric acid and cystine. 60-80% of stones contain calcium. They vary considerably in size from small 'gravel-like' stones, to large staghorn calculi.
