Acute oliguric renal failure due to accelerated (malignant) hypertension.

Abstract

Accelerated hypertension sometimes presents as acute oliguric renal failure, which may be difficult to distinguish from other causes of acute renal failure. Papilloedema need not be present in such patients even though the kidneys show typical vascular lesions of accelerated hypertension. Recovery of renal function may occur after a period of dialysis and vigorous treatment of the hypertension.
