About Kt/V
Kt/V is a dimensionless number used to quantify dialysis treatment adequacy, where:
- K = Dialyzer clearance of urea (mL/min)
- t = Dialysis time (min)
- V = Volume of distribution of urea (mL)
Clinical Targets
| Type | Target Kt/V |
|---|---|
| Hemodialysis | ≥ 1.2 per session |
| Peritoneal Dialysis | ≥ 1.7 per week |
Factors Affecting Kt/V
- Blood flow rate
- Dialyzer size
- Treatment time
- Residual kidney function
Why Kt/V Matters
Adequate Kt/V values are associated with better patient outcomes, including:
- Lower mortality rates
- Fewer hospitalizations
- Better quality of life
