[Renal biopsy in the aged].

Pathological findings in urinalysis in the aged persons are usually thought to be caused by pathologic processes other than glomerulopathy. Histological evaluation of renal tissue in older patients is extremely difficult due to coexistence of involuntary changes-hyalinosis, increase in mesangial matrix content, and vascular changes. The aim of the study was to evaluate frequency of glomerulonephritis, both primary and secondary in persons older than 60.
