Total Urea Clearance (KT, or Corrected Kt/V)

 

For Hemodialysis Twice Weekly Schedule

 

KT =

= (Kt/V) + (9.5 * (Kru / (total body water)))

 

For Hemodialysis Thrice Weekly Schedule

 

KT =

= (Kt/V) + (5.5 * (Kru / (total body water)))

 

where:

• Grotch (1991) uses 4.5 instead of 5.5 (Daugirdas) for thrice weekly hemodialysis

 

The Kru measured before starting a hemodialysis protocol is likely to drop after the hemodialysis has begun, and may reach 0.
