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.

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 ...

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]
Para-aminohippurate (PAH) clearance is a method used in renal physiology to measure renal plasma flow, which is a measure of renal function. [citation needed]PAH is completely removed from blood that passes through the kidneys (PAH undergoes both glomerular filtration and tubular secretion), and therefore the rate at which the kidneys can clear PAH from the blood reflects total renal plasma flow.
