Reversibility of acute renal failure in elderly patients with the nephrotic syndrome.

Acute renal failure may occur in the nephrotic syndrome due to minor glomerular changes, especially in the elderly. We describe five cases and review the literature. Previous renal damage due to ischaemia and drugs may be important in pathogenesis. We stress the importance of active management of these cases, as the renal lesions are reversible and recovery can be expected.
