title: [Physico-chemical mechanisms of the formation of calculi].
abstract: Urinary stones are formed in three steps: nucleation, growth and crystal aggregation. These steps are dependent on physicochemical factors such as oversaturation of the urine and presence of substances that promote or inhibit lithogenesis. These mechanisms result in the formation of crystalline particles large enough to be detained in the lumen of renal tubules.
