  • Title: [Ischemic nephropathy].
    Author: Mann J.
    Journal: Ther Umsch; 1994 Dec; 51(12):819-23. PubMed ID: 7784995.
    Abstract:
    Ischemic nephropathy encompasses renal insufficiency due to 3 different diseases, namely renal artery stenosis, so-called benign nephrosclerosis, and renal cholesterol embolism. All 3 disease entities may lead to a progressive loss of renal excretory function. If a patient presents with renal failure of unknown origin, renal artery stenosis should be looked for by color-coded duplex scanning or arteriography. The clinical presentation of benign nephrosclerosis in caucasians has no typical clues. Usually, a renal biopsy identifies this renal disorder in a patient with long-standing hypertension, moderate proteinuria and renal insufficiency. Cholesterol embolism typically affects several arterial trees, and is induced by arteriography in patients with arteriosclerosis of the aorta. The best treatment for ischemic nephropathy due to renal artery stenosis [conservative, angioplasty, surgery] is unknown because appropriately controlled trials are lacking. Invasive therapy should be considered in patients with bilateral renal artery stenosis or stenosis of a single functioning kidney, particularly if the affected kidney is not contracted. Arguments in favor of invasive therapy include the progressive nature of renal artery stenosis and the poor outcome of dialysis patients with this diagnosis as underlying renal disease.
