Kt/V — Dialysis Adequacy (Urea Clearance)

Calculates Kt/V (urea clearance × time / urea distribution volume), the primary measure of hemodialysis adequacy. Target Kt/V ≥ 1.4 per session (single-pool, spKt/V) for 3×/week hemodialysis per KDOQI guidelines. Inadequate dialysis is associated with increased cardiovascular mortality, hospitalization, and poor nutritional status in ESRD patients.
