Resumo

Background: Urolithiasis is a metabolic disease of complex and multifactorial etiology, characterized by uroliths formation in the urinary system. It becomes clinically important when obstruction occurs, with little chance of reversal of the situation, and prevention is the best option for maintaining the integrity of the reproductive capacity. For this, the aim of this research was to know the clinical and biochemical profile of urolithiasis and predict the evolution of the disease in Santa Ines sheep breed fed with calculogenic diet, as well as to evaluate the prevention potential of vitamin C. Materials, Methods & Results: In this study, 14 healthy male Santa Ines sheep, aged approximately 90 days, were divided into two groups (G1- without vitamin C and G2 - with vitamin C, 1 g/dayly/orally) fed on calculogenic diet for 120 days. The animals were examined weekly, including observation of clinical signs, and blood and urine analysis were performed. Final leukogram revealed leukocytosis by neutrophilia in G2. There was aciduria in 57.14% (G1) and 71.43% (G2) and the presence of blood cells, bacteria and sperm to the urinary sediment. There were hyperproteinemia and proteinuria, but no significant elevation in serum albumin and globulin, urea and creatinine concentrations. Urine urea remained high. Serum uric acid was higher in M15 and M16, although inferior to those obtained in urine. No hyperglycemia was reported and urine concentrations remained stable over time, with a peak observed at M16. Serum AST presented a significant increase in M12 and M13, but returned to normal just after. Urine revealed significant turbidity and density changes for G1 and G2. Haematuria was observed in G1 and G2; however, changes in color and odor were evidenced only in G2. It was verified that, although most of the animals presented aciduria, 42.86% of G1 and 28.57% of G2 presented alkaline urinary pH.[...](AU)
