Long-term outcome of dogs recovering from acute kidney injury: 132 cases.

Long-term survival of dogs with AKI is longer than previously described. Normalization of sCr in 99 dogs (75%) occurred, either at discharge or within the follow-up period. Normalization of sCr was not associated with long-term survival. Estimated MST of dogs with sCr normalization was not different compared with dogs that developed azotemic chronic kidney disease (CKD), presumably because of slow CKD progression rate. Etiology is an important factor determining sCr normalization and long-term survival, emphasizing the importance of the reversibility of renal injury rather than its severity.
