WebUrea reduction ratio (URR) is a measure of the proportionate reduction in blood urea nitrogen over the course of dialysis. It is calculated as: It is an alternative expression of the R term in the Daugirdas equation for sp Kt / V. For example, if a patient started dialysis with a BUN of 100 mg/dL and finished dialysis with a BUN of 30 mg/dL, R ... In medicine, Kt/V is a number used to quantify hemodialysis and peritoneal dialysis treatment adequacy.
