Previous issue date: 2016-02-19 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / Nesta dissertação, abordam-se as patologias do sistema urinário. Os dados referentes a estas enfermidades são relacionados aos casos diagnosticados na região sul do Rio Grande do Sul em um período de 36 anos. Com base nesses achados foram elaborados dois artigos científicos. No primeiro trabalho avaliaram-se todas as lesões do sistema urinário de cães, constantes nos protocolos de necropsia e exames histopatológicos do Laboratório Regional de Diagnóstico da Faculdade de
Veterinária da Universidade Federal de Pelotas, no período de 1978 a 2014. Foram encontrados diagnósticos de afecções do sistema estudado em 363 cães, correspondente a 4,04% 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 estavam a nefrite túbulo-intersticial (142 casos), geralmente
associada à 47 casos de Leptospirose. O trato urinário inferior (TUI) representou 6,9% dos casos destacando-se a cistite aguda com 19 casos de um total de 60 lesões do TUI. Neste estudo a insuficiência renal, aguda ou crônica, representou importante causa mortis em cães. No segundo artigo descreve-se um diagnóstico anatomo-patológico de metaplasia disontogênica uretral em um felino fêmea, de um mês de idade e sem raça definida. Havia histórico de aumento de volume abdominal desde o nascimento. Ainda apresentava disúria, eliminando a urina apenas por cistocentese, sondagem vesical ou gotejamento. Foi eutanasiado e na necropsia observou-se bexiga aumentada e dilatada, rins diminuídos e ureteres dilatados e tortuosos. Histologicamente havia metaplasia disontogênica da uretra e displasia
renal bilateral. Conclui-se nesta dissertação que as principais lesões renais foram a necrose tubular aguda, nefrite túbulo-intersticial, fibroplasia e glomeruloesclerose; e quanto ao TUI sobressaíram-se a cistite aguda, urolitíase, ruptura de bexiga e neoplasias primárias. / This thesis addresses the pathologies of the urinary system. The data concerning disorders of the urinary tract are related to cases diagnosed in southern Rio Grande do Sul in a period of 36 years. Based on these findings two papers were written. The first article assessed all the urinary tract lesions of canine, described in the necropsy reports and histopahtological tests from the Regional Laboratory of Diagnosis of the
College of Veterinary in the Federal University of Pelotas in the period from 1978 to 2014. From a total of 8980 diagnosis, 363 dogs were found to have affections of the urinary system, which represents 4,04% of diagnosis performed for that period and species. Renal injury accounted for 93.1% of the 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 the lower urinary tract (LUT) accounted for 6.9% of the cases where acute cystitis stands out with 19 cases of a total of 60 LUT injuries. In this study, renal failure, acute or chronic, represented an important cause of death in dogs. The second article describes an anatomopathological diagnosis of dysontogenic urethral metaplasia in a female, one monthold, mongrel cat. The animal had history of abdominal enlargement since birth and dysuria, eliminating urine only cystocentesis, urinary catheterization or drip. It was euthanized and in the necropsy was observed enlarged and distended bladder, reduced kidneys and dilated and tortuous ureters. Histologically, it had dysontogenic metaplasia of the urethra and bilateral renal dysplasia. It is concluded in this thesis that the main renal lesions were acute tubular necrosis, tubulointerstitial nephritis, fibroplasia and glomerulosclerosis; and when the LUT is concerned, acute cystitis, urolithiasis, bladder rupture and primary neoplasms stood out.
