The Examination of BUN and Creatinine Value in Cats withFeline Lower Urinary Tract Disease

Abstract

Feline Lower Urinary Tract Disease (FLUTD) is one of the most common diseases affecting cats. One type of FLUTD
that often occurs is urinary tract obstruction. Urinary tract obstruction makes it difficult for cats to urinate, causing urea and creatinine to be reabsorbed into the bloodstream. This study aimed to examine of Blood Urea Nitrogen (BUN) and creatinine values in cats with Feline Urinary Tract Disease (FLUTD). Cats with FLUTD often had kidney problems such as azotemia and chronic kidney disorders called Chronic Kidney Disease (CKD). Both conditions can be seen from high levels of BUN and Creatinine in the blood. The BUN and Creatinine levels were examined by taking blood serum from cats with FLUTD using a 3 cc disposable syringe and accommodated in a plain tube and then centrifuged at 3000 rpm for 10 minutes. The tool used to perform BUN and creatinine examinations is the VetTest Idexx Laboratory® blood chemistry examination tool. The result of the examination on 25 cats was 64% (16/25) had an increase in BUN values and 36% (9/25) had an increase in creatinine values. BUN and creatinine are waste products of metabolism that are filtered by the glomerulus and excreted in the urine. Elevated levels of BUN and creatinine in cats with FLUTD are due to the cat's inability to urinate as a result of urinary tract obstruction or decreased glomerular filtration rate. Based on the results, it can be concluded that cats with FLUTD will also have kidney problems, and additional therapy is needed to reduce BUN and creatinine levels.
