Peritoneal Dialysis Adequacy KT/V Formula

Dialysis is done using the peritoneum in the abdomen as the membrane is called as Peritoneal dialysis. Through this peritoneal membrane, all the fluid and dissolved foods are exchanged in blood. Hemodialysis and peritoneal dialysis treatment adequacy are quantified based on the KT/V number. The below Peritoneal dialysis adequacy KT/V formula helps you to calculate the adequacy based on height, weight, surface area, age, volume of urine in kidney etc.

Formula:

s=w0.425 × h0.725 × 0.007184
r=((v × u) /p ) / 1440
c=((((v × u)/p) / 1440) × 1.73) / ((w0.425 × h0.725)) × 0.007184)
a=((((v × u)/p)/1440)×1.73)/((w0.425 × h0.725) × 0.007184)) /1000
b=(((((v × u)/p)/1440) × 1.73)/((w0.425 × h0.725)× 0.007184)) ×10080
d=((n/p)×e)×7
x=((((((n/p) × e)×(1.73/((w0.425 × h0.725) × 0.007184))
g=(((((((v×u)/p)/1440)×1.73)/((w0.425 × h0.725)×0.007184))×10080)+(((((((n/p)×e)×7)×e)/p)×1.73)/((w0.425 ×P(h,0.725))×0.007184)))/f
i=(((((((v×u)/p)/1440)×1.73)/((w0.425 × h0.725)×0.007184))×10080)+(((((((n/p)×e)×7)×e)/p)×1.73)/(w0.425 × h0.725)×0.007184)))/l
if female
f=(-2.097)+(0.1069×h)+(0.2466×80)
l=(0.34454×h)+(0.183809×w)-35.270121
if male
f=2.447-(0.09156×y)+(0.1074 ×h)+(0.3362×w)
l= (0.194786*h) + (0.296785*w) - 14.012934



Where,

w = Weight
h = Height
s = Body Surface Area
a = RKCcc/min
b = RKCL/wk
l= Hume
g = kwat
i = khum
y = Age
f = Watson
d = Dialysate Clearance(L/week)
n = Dialysate Urea Nitrogen
e = Volume of Dialysate
x = Dialysate Clearance(L/week/1.73 m)
c = RKCcorrected
r = Residual Kidney Function
v = Volume of Urine in a day
u = Urine Urea Nitrogen
p = Plasma Urea Nitrogen
