AIM: To examine blood flow in renal and intrarenal arteries and its changes in the acute pharmacological test with @entity3371 in @entity1 with chronic @entity631 (CGN). MATERIAL AND METHODS: Renal circulation was studied in 50 @entity1 with CGN using ultrasound dopplerography (USDG) of renal vessels on the unit GE Logiq 400 CL PRO Series. The velocity and indices of peripheral blood resistance in the major renal artery (RA) and in intrarenal arteries were estimated. In 26 @entity1 the blood flow was studied again after intake of 50 mg @entity3371 . RESULTS: Poor renal blood flow was registered in cortical parenchyma in 36% CGN @entity1 (with @entity177 in 75%). Multifactorial regression analysis has demonstrated that only blood @entity1011 was independently related with slowing down of the blood flow at the level of RA and intrarenal arteries. Morphological index of activity correlated with resistance indices while a high sclerosis index correlated with @entity450 . Older @entity1 had higher resistance indices. @entity3371 significantly accelerated blood flow and insignificantly changed indices of peripheral resistance including those in @entity6192 @entity1 . CONCLUSION: Poor blood flow in the cortical layer of @entity8 in CGN, according to USDG, occurs rather frequently and was associated with @entity6192 and older age of the @entity1 . Blocking of renin-angiotensin system at the level of @entity2178 formation improves renal blood flow in most of the @entity1 .
