PERSISTENT NEPHROGRAM IN A CAT AFTER INTRAVENOUS UROGRAPHY

An 8-year-old cat was evaluated for recurrent bouts of stranguria, hem aturia and pollakiuria. Routine urinalysis, CBC and serum chemistries were unremarkable. Intravenous excretory urography was performed while the cat was sedated. The nephrogram was initially well opacified and increased in opacity during the 40 minutes that the study was performe d. Ureterogram and pyelogram failed to develop. Oliguria with little e xcretion of the contrast medium was documented. These findings are con sistent with either contrast medium associated hypotension or acute re nal failure. Treatment with aggressive fluid therapy and a continuous dobutamine infusion reestablished urine output after 2 hours.
