ABSTRACT: Normal kidney aging is related to tissue and functional changes that make older patients very vulnerable to environmental modifications. Numerous factors can accelerate the impairment of renal function during aging. It was a single-center retrospective study extending over a period of 30 years from 1984 to 2014 and includes patients older than 65 years, hospitalized for nephropathy requiring renal biopsy and monitored in our service. There were 6 men and 7 women with an average age of 69.38 ± 4.5 years. Mean serum creatinine was 267.15 ± 124 mmol/l. Eleven patients had renal failure. Histological lesions were: Extramembranous glomerulonephritis (EMGN): 1 case, focal segmental glomerular sclerosis (FSGS): 3 cases, membranoproliferative glomerulonephritis (MPGN): 1 case, IgA nephropathy: 1 case, glomerulonephritis with IgG4 fibrillar deposits (GN IgG4): 1 case, diabetic nephropathy: 2 cases, myeloma-associated tubulopathy: 1 case, acute tubular necrosis: 1 case, acute interstitial nephritis: 1 case, vascular nephropathy: 1 case. Kidney disease will increasingly become a geriatric illness. Nephrologists are encountering a growing group of elderly patients with diminished equation for estimated glomerular filtration rate (eGFR) that require evaluation and management.
