Kt/V and URR in hemodialysis
Estimates delivered hemodialysis dose in one session (spKt/V) from pre/post urea, duration, ultrafiltration and weight, and compares it with KDOQI targets.

Method · Limits of application
Daugirdas second generation 1993: variable-volume spKt/V; UF/post weight; URR; not equilibrated Kt/V
This formula estimates single-session spKt/V with a single compartment and volume correction; it is not equivalent to equilibrated or weekly Kt/V. Sampling technique and timing, units and dialysis regimen must match the method. KDOQI targets have their own context and source; analysis of the value alone does not confirm overall treatment adequacy.
Conditions of use
Check the population, units, inclusion and exclusion criteria, and version in the original source. A result alone does not establish a diagnosis, discharge decision or prescription.
Documented parameters
