Abstract

Extrarenal uremia lesions diagnosed in dogs at the Animal Pathology Laboratory of the Veterinary Hospital of the Federal University of Campina Grande - PB. Uremia can be understood as a syndrome due to prolonged azotemia of pre-renal, renal or post-renal origin. As lesions resulting from uremia are characteristic and multisystemic, being an important cause of death in dogs. Aiming to characterize the epidemiological, clinical and pathological aspects of uremic syndrome performed in a retrospective study in search of extrarenal uremia lesions diagnosed in dogs between the years 2006 to 2015, no Animal Pathology Laboratory, Federal University of Campina Grande. Of a total of 1,224 dogs necropsied in this period, 22 animals (1.7%) developed or modified according to uremia. A syndrome is manifested mainly in adult animals, with defined race. All animals were reported as uremia-compatible clinicians, with those related to the digestive system being most frequent, such as anorexia (54.5%), tongue ulcers (41%), diarrhea (36%) and vomiting (27%), Which can be attributed directly to the high frequency of uremic lesions in the gastrointestinal tract. The most affected systems are in descending order: digestive, respiratory, cardiovascular, bone, endocrine, renal and lymphatic. Complications such as ulcerative and hemorrhagic gastritis (86.3%), ulcerative glossitis (54.5%), non-collapsed lung and with porous appearance and sandy consistency (77.2%), endocarditis mural mural (18,1%), Fibrous osteodystrophy (27.2%) and parathyroid hyperplasia (18.1%). In the majority of cases, as extrarenal lesions of uremia were due to renal lesions, being more diagnosed an interstitial nephritis and a glomerulonephritis. In three cases, histological associa- tions in the renal parenchyma were consistent for leptospirosis. It was concluded that uremic syndrome is an important cause of death in dogs, being diagnosed non-LPA of the Veterinary Hospital of the Federal University of Campina Grande.
