To discover the cause of kidney stones, it is important to analyze the stone to identify the type. The urine must also be laboratory tested to determine the causes so that the most appropriate treatment can be provided.
Many factors contributing to the formation of kidney stones include:

1. Less urination.
2. Urinary tract infection.
3. Eating certain foods.
4. Taking certain medications.
5. Excessive amounts of certain substances in the urine, such as calcium (which can combine with oxalate or phosphate) or uric acid.
