Necropsy reports from 4,723 dogs examined from January 1990 to July 2010 in the Laboratório de Patologia Veterinária, Universidade Federal de Santa Maria, were surveyed. The main purposes of this retrospective study were to establish the prevalence and types of neoplasms of the urinary system in dogs. Neoplasms of the urinary system were present in 113 (2.4%) dogs. Twenty seven were primary neoplasms and 86 were metastatic or part of a multicentric tumor. The majority of the primary neoplasms were of epithelial origin. Thirteen dogs had primary renal neoplasms (prevalence of 0.27% over all dogs necropsied in the studied period). Cystadenocarcinoma/cystadenoma and renal cell carcinoma were the most prevalent primary renal neoplasms and transitional cell carcinoma was the most prevalent urinary bladder neoplasm. Metastatic (64 cases) or multicentric (22 cases) tumors affecting the urinary system were the most prevalent (86 cases [76.1%]). Among them, mesenchymal tumors were more common than epithelial tumors. Out of the 86 cases, most of them were localized in the kidney. Metastases of mammary tumors and multicentric lymphoma were the most prevalent histologic types.INDEX TERMS: Urinary system, diseases of dogs, epithelial and mesenchymal neoplasms, pathology.

“…Na rotina do Laboratório de Patologia Veterinária da Universidade Federal de Santa Maria (LPV-UFSM), neoplasmas representam a segunda causa de morte ou razão para eutanásia de cães da Mesorregião do Centro Ocidental Rio-Grandense, atrás apenas das doenças infecciosas, perfazendo 7,8% dos casos (Fighera et al 2008). A maior parte dos neoplasmas primários do SNC de cães da rotina de diagnóstico do LPV-UFSM são meningiomas (44,4%) (Fighera et al 2008).…”

Intracranial and supratentorial meningiomas were the most frequent in relation to the other intracranial or intraspinal sites. The intracranial ones were characterized mainly by clinical signs of thalamic-cortical alteration. Intraspinal ones were mainly characterized by ataxia. G-I meningiomas were the most frequent (63.6%) in dogs, followed by G-III (22.7%) and G-II (13.6%). GI were characterized by having the psammomatous subtype as the most frequent, more than one morphological pattern in the same tumor, one third presenting areas of invasion of nervous tissue, 71.4% of cases involving females, a mean age of 11 years, pure breed dogs as the most affected ones and for having the longest survival time after the manifestation of clinical signs. G-II meningiomas were characterized by having the chordoid subtype as the most frequent, invasion of nervous tissue in one third of cases, only females affected, a mean age of 12 years, two-thirds of the dogs affected were mongrels and the maximum survival time of 20 days. The G-III meningiomas were characterized by having the papillary subtype as the most frequent, invasion of the nervous tissue in 80% of the cases, 60% of the cases involving females, a mean age of 8 years, 80% of dogs affected were Boxers and the maximum survival time of 90 days. In conclusion, this study allowed to establish a relationship between the three histological grades observed in 22 cases of meningiomas in dogs with various clinical-epidemiological and pathological parameters, providing useful information for a better understanding of the correlation between the histological grading and the clinical evolution of these neoplasms.

“…As lesões do trato urinário têm sido classiϐicadas na literatura veterinária principalmente de acordo com sua distribuição e etiopatogênese (Maxie & Newman 2007, Serakides 2010, associando-se a fatores clínico--epidemiológicos e às repercussões da ocorrência dessas lesões (Cowgill & Elliott 2008, Lulich et al 2008, Polzin et al 2008. Várias delas são consideradas achados incidentais de necropsia (Maxie & Newman 2007, Serakides 2010, porém podem ser a causa da morte ou razão para eutanásia nessa espécie animal, muitas vezes associadas à insuϐiciência renal aguda ou crônica (Fighera et al 2008, Trapp et al 2010, Fleming et al 2011.…”

Pesq. Vet. Bras. 32(8) The aim of this study was to determine the prevalence, epidemiology, clinical signiϐi-cance, and possible associated causes of the urinary system lesions in dogs necropsied between January 1999 and December 2010 at the Laboratório de Patologia Veterinária of the Universidade Federal de Santa Maria (LPV-UFSM). To accomplish this, the necropsy reports were analyzed retrospectively. In this time frame, 3,189 dogs were necropsied and about 30% had lesions in the urinary system. In most of the dogs (79.1%), lesions were single and in about 21% they were multiple, totalizing 1,373 lesions. Out of them, 1,014 (73.8%) were observed in the kidney and 359 (26.2%) were in the lower urinary tract (LUT). One third of the lesions in the urinary system were causes of spontaneous death or reason for euthanasia (SD/EUTH) of the affected dogs. The other two third of the lesions were considered incidental ϐindings. The main renal lesions diagnosed, in descending order of prevalence, were: tubulointerstitial nephritis, infarct, granulomatous nephritis (parasitary), glomerulonephritis, metastatic/multicentric neoplasms, pyelonephritis/pyelitis, and hydronephrosis. The main LUT lesions, in descending order of prevalence, were: cystitis, presence of viral inclusions bodies (morbillivirus), urolithiasis, urinary bladder dilatation, urinary bladder rupture (with uroperitoneum), and metastatic/multicentric neoplasms. Epidemiological aspects such as gender, breed, and age of affected dogs had expressive variations according to the type of lesion diagnosed. Uremia was observed in a signiϐicant number of cases of SD/EUTH and was mostly due to renal lesions.INDEX TERMS: Lesions of the urinary tract, diseases of dogs, pathology.
