Medical Abbreviation RPF in Medical commonly refers to Renal Plasma Flow, which is a measure of the amount of plasma that passes through the kidneys per unit of time. [citation needed] PAH is completely removed from blood that passes through the kidneys (PAH undergoes both glomerular filtration and tubular secretion), and therefore the rate at which the kidneys can clear PAH from the blood reflects total renal plasma The MDRD GFR Equation estimates glomerular filtration rate based on creatinine and patient characteristics.

The fibrotic tissue typically surrounds the infrarenal aorta, inferior vena cava and iliac vessels. 0 to 1. A reduced GFR might indicate issues with the filtering capacity of the kidneys, such as in chronic kidney disease. Renal plasma flow is given by the Fick principle: This is essentially a conservation of mass equation which balances the renal inputs (the renal artery) and the renal outputs (the renal vein and ureter). This process may extend to neighboring structures, frequently entrapping and obstructing the ureters and eventually lead-ing to renal failure. What does RPF stand for in Renal?
