Kt/V

Nephrology A formula for measuring dialysis adequacy, where K = dialyzer clearance–volume of fluid completely cleared of urea in a single treatment–in mL/min; t = time; V = volume of water in a Pt's body. Cf URR.

Kt/V

A mathematical formula representing a dose of dialysis. K represents the relative efficiency of the dialyzer in removing harmful solutes from the circulation; t, the duration of the treatment; and V, the volume of urea in the body.

Increases in dialyzer efficiency and the duration of dialysis increase the dialysis dose, as do decreases in the total body volume of urea.
