Urinary calculus

The urinary calculus, also called lithiasis (from the Latin lithos, which means stone), corresponds to a sort of "pebble" formed by calcium and / or uric acid residues in the urine. When urinary stones are reformed or when they are numerous in the urinary tract, one speaks of lithiasis disease.

How is a urinary calculus formed? Normally, minerals in water or ingested foods are eliminated through the urine. Sometimes there may be a deposit of a tiny grain of mineral that has not been removed. Other tiny grains can come and settle on it. Gradually this grain will increase in volume and take a consistency reminiscent of a "pebble", then forming a urinary calculus.

When these crystallizations move in the urinary tract, they can cause renal colic, that is to say an acute and sudden pain crisis, which forces the patient to consult urgently.

To avoid the formation of a urinary calculus, certain preventive measures are necessary. It is recommended above all to drink 1.5 liters per 24 hours, on average, to avoid the overconsumption of meat, salt and calcium (cold cuts and cheeses), not to abuse tea and chocolate (rich in oxalates ).
