title: [Chronic renal failure in middle-aged and elderly persons].
abstract: The authors analyzed the frequency of chronic renal insufficiency (CRI) and the level of serum creatinine (200 mumol/l and more) in 10,350 outpatients aged over 60 (I group), 2400 persons of the same age in need of episodic hospitalization (II group), and in 1840 patients who died in hospital (III group). In the 1st group CRI frequency was 0.98%, in the 2nd group--6.9%, in the 3rd group--14.6%. Pyelonephritis (76.1%) and myelonephropathy (7.5%) were among CRI main causes. The authors underlined the multitude of factors causing CRI in middle-aged patients and the prospects of adequate therapy even in terminal states; CRI syndromes were considered for persons of this age group.
