In medicine, Kt/V is a number used to quantify hemodialysis and peritoneal dialysis treatment adequacy. K – dialyzer clearance of ureat – dialysis timeV – volume of distribution of urea, approximately equal to patient's total body water In the context of hemodialysis, Kt/V is a pseudo-dimensionless … See more K (clearance) multiplied by t (time) is a volume (since mL/min × min = mL, or L/h × h = L), and (K × t) can be thought of as the mL or L of fluid (blood in this case) cleared of urea (or any other solute) during the course of a single … See more Kt/V (in the context of peritoneal dialysis) was developed by Michael J. Lysaght in a series of articles on peritoneal dialysis. The steady-state solution of a simplified mass transfer equation … See more Hemodialysis • Hemodialysis Dose and Adequacy – a description of URR and Kt/V from the Kidney and Urologic Diseases Clearinghouse. See more The URR or Urea reduction ratio is simply the fractional reduction of urea during dialysis. So by definition, URR = 1 − C/C0. So 1−URR = C/C0. So by algebra, substituting into equation (4) above, since ln C/C0 = − ln C0/C, we get: See more Kt/V has been widely adopted because it was correlated with survival. Before Kt/V nephrologists measured the serum urea concentration (specifically the time-averaged … See more • It is complex and tedious to calculate. Many nephrologists have difficulty understanding it. • Urea is not associated with toxicity. See more WebJul 12, 2015 · Definition of "dose" in CRRT is volume of blood "purified." Measure of "dose" in CRRT: clearance rate of a representative marker solute. Practically: Dialysis dose is equivalent to the effluent rate in ml/kg/hour. Effluent rate is the ultrafiltration rate for haemofiltration (CVVH), or the sum of ultrafiltration rate and dialysis rate for CVVHDF
