ABSTRACT
Background: Dioctophymiasis is a disease caused by the nematode Dioctophyme renale and is a relatively common condition in dogs. The parasite affects the kidney, especially the right, enters the kidney capsule and causes destruction and atrophy of the parenchyma. The lesion severity depends on the amount of parasites affecting the kidney, the duration of the infection, number of kidneys involved and concurrent occurrence of kidney disease. The diseases clinical presentation may be asymptomatic or with nonspecific clinical signs. The diagnosis is based on ultrasound examination and the detection of eggs in urine, however, diagnosis is often reached only through necropsy or histopathology. This study aimed to analyze the dog kidney anatomical and pathological changes when parasitized by Dioctophyme renale. Materials, Methods & Results: The kidneys of 21 dogs diagnosed with dioctophymiasis were nephrectomized, analyzed by ultrasound and forwarded to macro and microscopic analysis. Macroscopically, the kidney size was measured as well as its renal capsule thicknes. The presences of dilatation of the renal pelvis and ureter, as well as changes of the capsule, were also observed. These fragments were collected and submitted for routine analysis and stained with hematoxylin and eosin. Histopathological examination was performed blindly by three evaluators. The intensity of [...]

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)

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)
