To prevent the recurrence of calcium oxalate stones, it is essential not to restrict dietary calcium intake, as adequate consumption helps block the formation of these crystals.

This advice is perfectly aligned with current urological recommendations. Contrary to a widespread misconception, limiting calcium is counterproductive: dietary calcium binds to oxalate in the intestine before it reaches the kidneys, thereby preventing its absorption and urinary crystallization. Research, including expert consensus and risk factor analyses, confirms that a normal calcium intake (800 mg to 1,200 mg/day) is protective. The fundamental pillar of prevention remains sufficient hydration (aiming for 2 liters of urine per day) to dilute mineral salts. There is no exaggeration here, as the statement reflects the standards of care for calcium-based lithiasis.
