A RETROSPECTIVE STUDY OF END-STAGE RENAL DISEASE IN CAPTIVE POLAR BEARS (URSUS MARITIMUS)
This retrospective study summarizes 11 cases of end-stage renal disease (ESRD) in captive polar bears (Ursus maritimus) from eight zoologic institutions across the United States and Canada. Ten bears were female, one was male, and the mean age at the time of death was 24 yr old. The most common clin...
