Kt/V
In medicine, Kt/V is a number used to quantify hemodialysis and peritoneal dialysis treatment adequacy. K – dialyzer clearance of urea t – dialysis time V – volume of distribution of urea, approximately equal to patient's total body water In the context of hemodialysis, Kt/V is a pseudo-dimensionless number; it is dependent on the pre- and post-dialysis concentration (see below).
