Stone removal treats the current stone. Long-term prevention starts with understanding why it formed and choosing changes that fit your health.

Agree a fluid plan
Drink water regularly across the day. Ask your clinician how much you should drink and whether a urine-output target is useful; heat, exercise and sweating change your needs.
If you have kidney failure, heart failure or a prescribed fluid restriction, follow your individual limit. Do not force large amounts of water to treat sudden stone pain.
Match food choices to your stone
Cut back on excess salt and very salty packaged foods. Keep a balanced diet and a healthy weight. Your stone analysis and urine results guide any limits on animal protein or high-oxalate foods.
Do not routinely stop milk, curd or other calcium-containing foods. Normal dietary calcium can be helpful. Discuss supplements and restrictive diets with your clinician or dietitian.
Keep your prevention follow-up
If asked, save a passed stone for analysis. Repeated stones may need blood tests and a timed urine collection to identify treatable causes.
Take prevention medicines only as prescribed and attend planned scans or reviews, even when pain has stopped. Prevention reduces risk but cannot promise that stones will never return.
