Objective. To assess the intrarenal blood fl ow in hypertensive patients at orthostatic test. 79 subjects (36 males and 43 females) with arterial hypertension of II stage were enrolled. The renal blood fl ow was investigated using Doppler study with the spectral analysis at level of interlobar arteries. The direct relation between pulsatility index and pulse pressure was found (r = 0,52; p = 0,0001). Peripheral resistance and vascular rigidity were higher in patients with increased blood fl ow acceleration time in interlobar arteries at orthostatic test. Thus, Doppler study of intraparenchymal blood fl ow at orthostatic test can be used for early diagnosis of structural and functional changes of renal arteries.
