A 3-year-old male castrated domestic shorthair cat was presented with an acute history of lethargy and decreased appetite. Pertinent physical examination abnormalities included palpable irregularity of the right kidney and pain on palpation of the left kidney. Ultrasonographic imaging of the abdomen revealed gas present at the corticomedullary junction of the left kidney, consistent with emphysematous pyelonephritis, as well as emphysematous cystitis. While quantitative urine culture via pyelocentesis yielded a negative culture, a sample via cystocentesis was positive for Escherichia coli and emphysematous changes were presumed most likely secondary to an ascending infection. The purpose of this report is to describe the temporary management of ureteral obstruction secondary to emphysematous pyelonephritis using a ureteral stent in a cat.
