Standardized Kt/V, also std Kt/V, is a way of measuring dialysis adequacy. It was developed by Frank Gotch and is used in the United States to measure dialysis. Despite the name, it is quite different from Kt/V. In theory, both peritoneal dialysis and hemodialysis can be quantified with std Kt/V.
where C is the concentration [mol/m 3]; t is the time [s]; K is the clearance [m 3 /s]; V is the volume of distribution [m 3]; From the above definitions it follows that is the first derivative of concentration with respect to time, i.e. the change in concentration with time.
A more accurate relationship between URR and Kt/V can be derived by single-pool, variable volume urea kinetic modeling. A simplified estimating equation also can be used. [ 2 ] This gives results that are quite similar to formal urea modeling as long as dialysis treatments of 2–6 hours in duration are given, and Kt/V is between 0.7 and 2.0.
In nephrology, dialysis adequacy is the measurement of renal dialysis for the purpose of determining dialysis treatment regime and to better understand the pathophysiology of renal dialysis. [1]
The heavy green line shows the relation when UF/W - 0.03. So in practice, because of urea generation and UF/W, a 63% URR (0.63) results in a Kt/V of about 1.15 instead of only 1.0 (see graph). KDOQI hemodialysis adequacy standards are written in terms of either Kt/V or URR, with Kt/V being the preferred choices. But a patient may meet one ...
