WebClearance. Renal clearance uses the rate at which a compound is “cleared” from the body, i.e., is excreted in the urine, to determine aspects of renal function. The practical aspect of the clearance principle is that by applying it to select compounds, one can estimate glomerular filtration rate and renal plasma flow. Weband clearance. It is important to realize that `good’ ± i.e. low ± pre-dialysis urea concentra-tions may re¯ ect poor protein intake just as well as adequate dialytic clearance. Consequently, to assess the dialysis process accurately, modelling of urea kinetics is required that simulates the movement of urea to, from and within the body
WebRenal clearance of a substance refers to how quickly a particular substance is removed from the plasma by the kidney and excreted in urine. So something with a high renal … WebBy definition, [ 1] solute clearance ( K) is the ratio of mass removal rate ( N) to blood solute concentration ( C B ): K = { {N} \left/ { { {C_ {\text {B}}}}} \right.} For a hemodialyzer, mass …

WebThe glomerular filtration rate (GFR) describes the volume of fluid filtered from the renal (kidney) glomerular capillaries into the Bowman's capsule per unit time. Creatinine clearance is the volume of blood plasma that is cleared of creatinine per unit time and is a useful measure for approximating the GFR.
