Angiotensin II directly increases glomerular filtration pressure by causing constriction of the efferent arterioles.
Despite the increase in renal blood flow, the pressure within the glomerulus remains unaltered owing to compensatory effects on the afferent and efferent arteriole, but this only occurs in a normal kidney.
Renal artery stenosis is a contraindication for ACE-inhibition: where there is impaired flow into the glomerulus, angiotensin II maintains glomerular filtration pressure by constricting the efferent arteriole.
