PD KT/V Calculator

Kt/V is used to measure the hemodialysis and peritoneal dialysis treatment adequately. Here 'K' refers to dialyzer clearance of urea, 't' is dialysis time and 'V' refers to volume of distribution of urea, approximately equal to patient's total body water. The calculation of Peritoneal Dialysis Adequacy KT/V is simple, because the fluid drained will be close to 100% saturated with area. Use this PD KT/V calculator to find the body surface area, residual kidney function and other units.

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

Example:

A 36 year old man weighing 60 kg with a height of 165 cm, volume of urine in a day of 200cc, urine area nitrogen of 20mg/dL, plasma urea nitrogen of 50mg/dL, dialysate urea nitrogen of 12mg/dL, volume of dialysate as 35 L/day. Calculate Body Surface Area (BSA) and Residual Kidney Function.

Solution:

BSA= 600.425 × 1650.725 × 0.007184
= 1.6587 cm2
Residual Kidney Function = ( (200 × 20) / 50 ) / 1440
= 0.0556 cc/min
