Adequate water intake is the most effective preventive measure.
Dr. Marc Aubry
Internist
In simple terms
Kidney stones affect 10% of the population at some point. After a first episode, half will recur within 10 years without prevention.
What you need to remember
- Acute management — Hydration, NSAIDs (when not contraindicated), and alpha-blockers to facilitate stone passage.
- Long-term prevention — Drink 2.5-3 L water daily, moderate salt and animal protein, maintain adequate calcium intake (low calcium increases risk), reduce oxalate-rich foods if calcium-oxalate stone former.
Sudden severe flank pain radiating to the groin, nausea, vomiting, blood in urine — the classic renal colic.
Causes
- Dehydration
- High salt or animal protein intake
- Obesity
- Some medications
- Anatomical abnormalities
