WebAutoregulation is important in maintaining RBF, hydrostatic pressure in the glomerular capillary (PGC ), and GFR in the presence of this stenosis. The administration of drugs to lower the systemic blood pressure also lowers the pressure distal to the stenosis; accordingly, the RBF, P GC, and GFR decrease. WebRenal autoregulation may have ﬁrst been described by Rein in 1931 (125). However, as early as 1902, Bayliss (12) ob- served that the renal vasculature exhibits a profound vasocon- striction when the kidney was subjected to elevated pressure. Bayliss viewed the renal response as an example of the myo- genic response of vascular beds.

Renal blood flow is between 1.0 and 1.2 litres per minute per 1.73 m 2 of body surface area. The majority of blood flow to the kidney is directed to the cortex, with only a small proportion delivered to the medulla, where sodium transport by the thick ascending limb of the loop of Henle accounts for a high oxygen consumption. triplecheck cadenceWebImpaired Renal Autoregulation Autoregulation normally occurs between systolic blood pressures of 80 and 150 mm Hg, and between these ranges, renal blood flow, glomerular pressures, and GFR are maintained. Below 80 mm Hg, this autoregulation fails, and ischemic injury may result. triplecheck

Webdata, let's now turn to autoregulation. It appears that renal blood flow autoregulation is mediated primarily by resistance changes in the afferent arteriole [4].
