[Estimation of the dialysis time based on a simplified algorithm for urea kinetics].
A simplified method of calculating the dialysis time based upon urea kinetic modeling equation: Ct = C0 e exp - (Kt/V) is presented together with a table of urea clearance values for most commonly used dialyzers. The method is handy and helpful to prescribe dialysis time either in chronic uraemics or in patients with acute renal failure on hemodialysis. Estimation of a patient's urea distribution volume equal to the total body water and blood flow through the dialyzer are the key points in the described calculations.
