tvpjournal.com | March/April 2015 | TODAy'S VETERINARy PRACTICE FELINE CHRONIC KIDNEy DISEASE Peer Reviewed 41 words, the investigators had no way to retrospectively identify cats with serum creatinine concentrations between 1.6 and 2.3 mg/dL. The remainder of the staging system used in this study correlated with standard IRIS stages. Notice the stepwise decline in survival as CKD stage increases: 1151 days for Stage 2b cats (which would be higher if all stage 2 cats had been included) versus 679 days for Stage 3 cats and 35 days for Stage 4 cats. This trend is not surprising, but the actual numbers facilitate better prognostication and emphasize early diagnosis. CKD = chronic kidney disease; GFR = glomerular fltration rate; IRIS = International Renal Interest Society; SDMA = serum symmetric dimethyl- arginine; USG = urine specifc gravity References 1.
