1. Metabolic abnormalities: when the body has metabolic abnormalities, high calcium urine, high oxalic acid urine, high uric acid urine, resulting in the deposition of different ions and compounds, the formation of urinary stone crystals.
2. Local etiology: mainly including urinary tract infection, urinary tract obstruction, etc., resulting in crystals easily deposited in poor drainage sites, causing urine retention, thus inducing the formation of urinary stones.
