Background: Dioctophyma renale is a globally occurring nematode that parasites the kidneys, and to a lesser extent, can be found in other organs or free in the abdominal cavity. Has the capacity to destroy the renal parenchyma. For the most part, parasitized animals are asymptomatic. The diagnosis is made through urinalysis and ultrasonography. However most the cases are diagnosed only at necropsy. As treatment nephrectomy of the affected kidney is the technique of choice. Therefore, the aim of this work was to report the case of a dog, seven months old, treated surgically by nephrectomy of the right kidney due to the destruction of the renal parenchyma caused by D. renale.Case: A 7-month-old Australian Cattle Dog, with a history of hematuria, was attended in a Florianópolis Veterinary Hospital. At the physical examination of the patient, no change was found, being extremely active. Abdominal ultrasonography, urinalysis, CBC and biochemical profile were requested. Abdominal ultrasonography showed the presence of cylindrical and rounded structures, with a hyperechogenic wall and a hypoechogenic center, compatible with D. renale, located in the right kidney. Urinalysis revealed the presence of D. renale eggs. The erythrogram showed mild anemia and the leukogram showed neutrophilic leukocytosis. Calcium, creatinine, alkaline phosphatase, phosphorus, alanine aminotransferase and urea dosages showed values within normal limits. As treatment, nephrectomy of the right kidney was performed by laparotomy. The kidney was presented with destruction of the renal parenchyma and a single parasite was removed from its interior, measuring 54 cm in length. Histopathological analysis of the affected kidney revealed diffuse pronounced fibrous connective tissue proliferation, increased urinary space with decreased glomerular tuft and increased glomerular to tubule ratio. The nephrectomy was curative and ceased the patients hematuria.[...](AU)
