Anatomo-pathological and epidemiological analysis of urinary tract lesions in dogs / Análise anatomopatológica e epidemiológica de lesões do trato urinário de cães

ABSTRACT

In dogs, diseases of the urinary tract are common and can be caused by disorders of varied etiology. The objective of this study was to classify qualitatively and quantitatively urinary tract lesions of 363 dogs, which were classified according to its anatomical distribution and etiology. The data was obtained from the revision of 36 years of protocols from the Regional Laboratory of Diagnosis (LRD/UFPel) and it represents 4.0% of diagnoses from a total of 8980 for that period and species. Renal injury accounted for 93.1% of cases, with 309 being primary kidney lesions; from which the main lesions were the tubulointerstitial nephritis (142 cases) often associated with Leptospirosis (47). Injuries of lower urinary tract accounted for 6.9% of the cases where acute cystitis stands out (19). In this study, renal failure, acute or chronic, represented an important cause of death in dogs.(AU)

RESUMO

Em cães, as doenças do trato urinário são frequentes e podem ser causadas por desordens de etiologia variada. O objetivo deste trabalho foi classificar qualitativa e quantitativamente lesões do trato urinário de 363 cães, as quais foram classificadas de acordo com a distribuição anatômica e etiologia. Os dados foram obtidos em uma revisão de protocolos de 36 anos do LRD/UFPel e corresponderam a 4,0% do total de 8980 diagnósticos realizados no período para a espécie. As lesões renais representaram 93,1%, sendo 309 primárias do rim; dentre as principais lesões, está a nefrite tubulo-intersticial (142 casos), geralmente associada à Leptospirose (47). O trato urinário inferior representou 6,9% dos casos, destacando-se cistite aguda (19). Neste estudo, a insuficiência renal, aguda ou crônica, representou importante causa mortis em cães.(AU)
