Kidney Dialysis

Urea Reduction Ratio (URR) Calculator

This Urea Reduction Ratio (URR) calculator evaluates the dialysis efficiency based on the urea reduction ratio (URR) for patients with acute tubular necrosis. The URR ranges from 0 to 100%, with higher values indicating better dialysis efficiency.

Measurement	Value	Standard Range
Pre-Dialysis Urea (mg/dL):		30-60 mg/dL
Post-Dialysis Urea (mg/dL):		10-20 mg/dL
