People who have a family history of stones or who had more than one stone are likely to develop another.
If a person is at risk for developing stones, the doctor may perform certain blood and urine tests. These tests will determine which factors can be best altered to reduce that risk.
Some patients will need medicines to prevent stones from forming.
People with chronic urinary tract infections and stones will often need the stone removed if the doctor determines that the infection results from the stone’s presence. They should receive careful follow-up to be sure the infection has cleared. Source: NIDDK
