Pyelonephritis (Kidney Infection)
Katniss, an adorable five-and-a-half-year-old cat, came into WVRC-Racine ER for very nonspecific signs - lethargy, weakness, hiding, and a decreased appetite. On physical exam, Dr. Miesbauer felt she was thin, dehydrated, and weak. Blood work was performed and showed very elevated kidney values with several electrolyte imbalances, and Katniss was diagnosed with kidney failure. Although the cause of the kidney failure was unknown, there was concern of infection, cysts, cancer, or underlying kidney disease that was complicated by something else. Katniss was hospitalized for intensive supportive care including IV fluids, IV antibiotics, and medications to support her GI tract. Katniss was the quintessential patient - always purring and looking for love!
Luckily, Katniss defied the odds - the following day, her kidney values GREATLY improved, she was eating, and she was much more energetic! After an additional 24 hours of IV fluids, her kidney values completely normalized, which was phenomenal! Given her rapid and complete response to supportive care, it was thought that she had a kidney infection (pyelonephritis).
Katniss is now feeling great and is back to her normal self. Way to go Katniss! We are so happy for you and your family!
