We performed experiments in the two-kidney, one clip Goldblatt hypertensive dog to see whether angiotensin converting enzyme (ACE) inhibition could improve the sensitivity of hippurate renography in detecting renal artery stenosis. Ten dogs on a sodium-restricted diet were studied before and after induction of a renal artery stenosis. In the absence of renal artery stenosis nine dogs showed normal renograms before ACE inhibition, and one was false positive. During ACE inhibition all 10 renograms were normal. With a renal artery stenosis 50% of the renograms were false negative, whereas a 100% sensitivity was reached during ACE inhibition. The alterations induced by the ACE inhibition on the renograms were not related to changes in renal blood flow. In conclusion, ACE inhibition markedly improved the sensitivity of hippurate renography in the two-kidney, one clip dog.

D012078	Renal Artery Obstruction	Narrowing or occlusion of the RENAL ARTERY or arteries. It is due usually to ATHEROSCLEROSIS; FIBROMUSCULAR DYSPLASIA; THROMBOSIS; EMBOLISM, or external pressure. The reduced renal perfusion can lead to renovascular hypertension (HYPERTENSION, RENOVASCULAR).

D004285	Dogs	The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE. They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065)	Canis familiaris,Dog
D006626	Hippurates	Salts and esters of hippuric acid.
D000806	Angiotensin-Converting Enzyme Inhibitors	A class of drugs whose main indications are the treatment of hypertension and heart failure. They exert their hemodynamic effect mainly by inhibiting the renin-angiotensin system. They also modulate sympathetic nervous system activity and increase prostaglandin synthesis. They cause mainly vasodilation and mild natriuresis without affecting heart rate and contractility.
