Summary at a GlanceAs the population ages, large numbers of elderly patients will present with kidney diseases. Kidney biopsy for elderly patients is generally well tolerated and informative. Compared with younger adults, IgA nephropathy in the elderly carries a poor prognosis. In patients with intercurrent infections, IgA‐dominant postinfectious GN should be carefully differentiated from idiopathic IgA nephropathy. Existing ESRD and mortality prediction models/scoring systems for IgA nephropathy may not be generalized to elderly patients.
