Renal papillary necrosis in the tiger
Acta Zoologica Et Pathologica Antverpiensia
|February 1, 1978
Summary
Renal papillary necrosis in tigers, characterized by liquefaction and cortical scarring, may be caused by dehydration-induced reduced renal perfusion in kidneys with compromised blood supply. This condition shares similarities with cases in domestic animals and humans.
Area of Science:
- Veterinary Pathology
- Comparative Pathology
- Nephrology
Background:
- Renal papillary necrosis is a recognized condition in various mammalian species.
- Tigers, as large felids, can be susceptible to unique pathological conditions.
- Understanding renal pathology in exotic animals aids in comparative disease analysis.
Purpose of the Study:
- To describe two cases of renal papillary necrosis in tigers.
- To characterize the pathological lesions associated with this condition in tigers.
- To compare the findings in tigers with existing literature on renal papillary necrosis in other species.
Main Methods:
- Gross and histopathological examination of kidneys from two deceased tigers.
- Detailed description of observed lesions, including necrosis, liquefaction, inflammation, and cortical scarring.
- Comparative analysis of findings with published data on renal papillary necrosis.
Main Results:
- Both tigers exhibited renal papillary necrosis with extensive liquefaction and minimal inflammation.
- Pronounced cortical scarring was a consistent finding in both cases.
- Terminal vomiting and severe dehydration were noted in both animals prior to death.
Conclusions:
- Renal papillary necrosis in these tigers was likely precipitated by reduced renal perfusion due to dehydration.
- Pre-existing chronic cortical scarring may have compromised medullary blood supply, exacerbating the condition.
- The observed lesions share similarities with renal papillary necrosis reported in domestic cats, humans, and other domestic animals.
