If renal function deteriorates therapeutic adjustments may be indicated. CKD that is categorized as Stage I or early Stage II CKD nonazotemic CKD could be diagnosed in dogs with renal proteinuria persistent proteinuria with an inactive urine sediment urine concentrating deficits increases in serum creatinine over time that remain in the normal range eg serum creatinine that increases from 06 to 12 mgdL could indicate a 50 percent reduction in nephron.

By definition chronic renal failure CRF or chronic kidney disease CKD is the inability of the kidneys to efficiently filter the blood of waste products not the inability to produce urine.
Using creatinine as a continuous variable increased creatinine was associated with a hazard ratio of 1383 95 CI. The International Renal Interest Society IRIS was formed in 1998. The goal in dogs with stage 3 CKD would be to maintain stable renal function.
Stage 1 CKD includes dogs and cats with CKD that are not azotemic while stage 2 CKD includes dogs and cats that are mildly azotemic Table 2.

1 It is the most common kidney disease in small animals with an estimated prevalence of up to 7 in dogs.

Overall frequency of renal 2-HPTH was 76 in a recent study of dogs with CKD encountered in 36 of IRIS stage 1 50 in stage 2 96 in stage 3 and 100 in IRIS stage 4 Cortadellas et al 2010. An early aim was to develop a staging system for chronic kidney disease CKD in dogs and cats intended to facilitate communication about the diagnosis and management of this. As compared to dogs with stages 3 and 4 CKD dogs with stage 2 CKD had a hazard ratio of 0346 95 CI.
Once a diagnosis of CKD has been made IRIS staging can be done. In IRIS CKD Stage 2 patients with low body condition scores SDMA 25 µgdl may indicate the degree of renal dysfunction has been underestimated. Senior BVSc DACVIM SAIM DECVIM-CA in the June 2017 issue of Clinicians Brief.
Ironically most dogs in kidney failure produce large quantities of urine but the bodys toxic. In IRIS CKD Stage 2 patients with low body condition scores SDMA 25 µgdl may indicate the degree of renal dysfunction has been underestimated. Stage 1 Chronic kidney disease occurs when the blood creatinine is less than 14 mgdl and the SDMA level is 14-18mgdl.
0119 to 0999 P 05 and 016 95 CI. Stage 2 CKD Patients. Staging is based initially on fasting blood creatinine or fasting blood SDMA.
