Kalkulator Kt/V (termasuk URR)

Medical Calculator – SonDoctor.com

URR = (1 – [Post-dialysis Urea / Pre-dialysis Urea]) × 100
Kt/V = -ln(R – 0.008 × t) + (4 – 3.5 × R) × UF/W
R: Post-dialysis Urea / Pre-dialysis Urea
t: Dialysis time (hours)
UF: Ultrafiltration volume (L)
W: Post-dialysis weight (kg)

Pre-dialysis BUN (mg/dL):
Post-dialysis BUN (mg/dL):

Dialysis time (hr):
Ultrafiltration (L):
Post-dialysis weight (kg):

URR: Urea Reduction Ratio (target ≥ 65%)
spKt/V: Single-pool Kt/V (target ≥ 1.2; recommended ≥ 1.4)
eKt/V: Equilibrated Kt/V (target ≥ 1.05)
*eKt/V = spKt/V – (0.6 × spKt/V / t) + 0.03 [AVF]
*eKt/V = spKt/V – (0.47 × spKt/V / t) + 0.02 [catheter]
