The present study evaluated the glomerular and tubular alterations associated with mammary carcinoma in bitches. Eleven animals was used for control and 32 bitches with diagnosis of mammary carcinoma was assisted by Oncology and Obstetrics Service of the Veterinary Teaching Hospital Governador Laudo Natel of Faculdade de Ciências Agrárias e Veterinárias - UNESP, câmpus de Jaboticabal. The experimental protocol included obtaining clinical history and examination inherent to the blood count, serum biochemistry, urinary fractional excretion of sodium, electrophoresis of serum and urinary protein and blood pressure in combination with the evaluation of renal tissue obtained by tru-cut after the achievement of ovariohysterectomy (OH), which were evaluated by light, immunofluorescence and transmission electron microscopy (TEM). Serological tests, PCR and hormonal tests were used for animal’s exclusion or inclusion in their respective groups. Carcinoma group had higher concentration of globulins, haptoglobin and serum transferrin, indicating probable stimulation and production of substances from mammary carcinoma. Proteinuria associated with higher frequency of low, medium and high molecular weights of urinary proteins and their relationship with glomerular and tubular alterations evidenced by light microscopy and the association of these findings to the deposit of different classes of immunoglobulins and complement C3 (C3) in renal immunofluorescence, and the presence of subendothelial electron-deposits in the glomerulus might support the hypothesis of existence of renal alterations associated with mammary carcinoma
