Determinação da relação proteína/creatina urinária no diagnóstico precoce de nefropatias em gatos acometidos de doença do trato urinário inferior.

Abstract

A disease of great importance in Clinical Small Animal Disease is Feline Lower Urinary Tract (FLUTD) which, if not treated in time, can lead to secondary renal complications. In order to detect glomerular injury, veterinarians use parameters such as Urea and serum creatinine as a diagnostic. However, these substances only identify kidney injury when at least 75% of nephrons are functionally compromised, it is not favorable since the early diagnosis is desired. The use of analysis of the protein / creatinine ratio is a urinary alternative to diagnoses, because through this determination can detect renal impairment when only 25% of the parenchyma is affected. This is work to evaluate the importance of using the determination of protein / creatinine ratio in early diagnosis of urinary kidney injury secondary to the Feline Lower Urinary Tract Disease. Were included in this study, 12 cats treated at the Medical Clinic of Small Animal Veterinary Hospital University Federal de Campina Grande, campus Ducks, diagnosed with Feline Lower Urinary Tract Disease in the period August 2013 to July 2014. The results showed that 66.6% of the cats had values of the ratio P/C Urinary <0.2 and 33.4% had values between 0.2 and 0.4, thus did not develop until moment no evidence of renal disease. The protein/creatinine ratio urinary might be useful as a diagnostic tool to monitor these and other cases of cats with Lower Urinary Tract disease.
