In the physiology of the kidney, renal blood flow (RBF) is the volume of blood delivered to the kidneys per unit time. In humans, the kidneys together receive roughly 25% of cardiac output, amounting to 1.2 - 1.3 L/min in a 70-kg adult male. It passes about 94% to the cortex. RBF is closely related to renal plasma … See more Renal plasma flow is the volume of plasma that reaches the kidneys per unit time. Renal plasma flow is given by the Fick principle: $${\displaystyle RPF={\frac {U_{x}V}{P_{a}-P_{v}}}}$$ See more If the kidney is methodologically perfused at moderate pressures (90–220 mm Hg performed on an experimental animal; in this case, a dog), then, there is a proportionate … See more Values of Pv are difficult to obtain in patients. In practice, PAH clearance is used instead to calculate the effective renal plasma flow (eRPF). PAH (para-aminohippurate) … See more • Renal Clearance Techniques See more WebJul 1, 2012 · Glomerular filtration rate (GFR) and renal blood flow (RBF) are normally kept constant via renal autoregulation. However, early diabetes results in increased GFR and the potential mechanisms are debated. Tubuloglomerular feedback (TGF) inactivation, with concomitantly increased RBF, is proposed but …

WebJul 25, 2024 · RBF comprises roughly 20% of the total cardiac output; it is roughly 1 liter per minute. Flow in the kidney follows the same hemodynamic principles seen elsewhere in other organs. RBF is proportional to the difference in pressures between the renal artery and vein, but inversely proportional to the vasculature resistance.
