Uric acid excretion disorders include reduced renal tubular secretion, reduced glomerular filtration, etc.; can lead to elevated uric acid levels in the patient’s body inborn purine metabolism disorders, including type I glycogen accumulation disorder, hypoxanthine-guanine phosphoribosyltransferase defects, etc.; secondary uric acid increases include drugs (furosemide, hydrochlorothiazide, etc.), certain blood disorders, and so on.
