- Kt/V.Hemodialysis
- Derived from Urea Reduction Ratio, no patient weight. Formula is 100 x (1 - [C1/C0]), in which C1 is the blood urea nitrogen measured 5 minutes after the end of dialysis and C0 is the predialysis blood urea nitrogen. It is a quantitative measurement of an individual patient's urea clearance during a single hemodialysis treatment and can be used as a proxy for the adequacy of solute clearance during a treatment.
