Estimating total urea removal and protein catabolic rate by monitoring UV absorbance in spent dialysate.
Protein catabolic rate over lean body mass ratio: a more rational approach to normalize the protein catabolic rate in dialysis patients.
 Nonstandard abbreviations: BSA, bovine serum albumin; BUN, blood urea nitrogen; and nPCR, normalized protein catabolic rate
. Table 1.
Significant improvements in normalized protein catabolic rate
(nPCR) and dry weight were shown, and significant decreases in weekly fluid gains were reported.
It was found that patients in the group with > 5% gain exhibited higher Kt/V, solute removal index, urea reduction ratio, predialysis blood urea nitrogen (BUN), urea removal rate, and protein catabolic rate
(PCR) than those in the < 5% group.
Also, the protein catabolic rate
, an indicator of nutrition, can be calculated using urea kinetics.
