title: Renal artery stenosis--then and now.
abstract: Diagnostic approaches evolve steadily. Selective renal arteriography and determination of renal vein renins have replaced differential clearances and translumbar aortography. The hydrated intravenous pyelogram remains helpful in assessing physiologic significance and complements both aortography and renin determinations. Except for young patients, medical treatment rather than surgical management usually is preferred.
