The veterinary ultrasonographic techniques have increased in the veterinary doctor’s daily work, therefore training and knowing how to use ultrasound equipment have become needful to the animals healthcare professionals. It’s important remember that ultrasound equipment makes possible getting valuable pathological data from animals’ health. In this background, the renal ultrasonographic test has gotten an important place and, nowadays, it is possible measure with accuracy the caprine renal morphometrics parameters (Capra hircus). Through ultrasonographic techniques, it has done a stocktaking with three groups of normal goats: older than 18 months (46.3±17.4 months), younger than 6 months (3.0±1.0 months) and age between 6 and 18 months (9.0 4.3 months), totalizing 30 samples of the female Saanen kind. In longitudinal section of the kidneys, measured the length and breadth and, in transverse section, measured the height (or thickness). The values obtained calculated the renal, cortical and medullary volumes, besides corticomedullary correlation. The renal length of the groups younger than 6 months, age between 6 and 18 months and older than 18 months had mean and standard deviation of 4.20±0.36cm; 5.56±0,40cm; and, 6.77±0.64cm, respectively. To the renal volume theses groups had mean and standard deviation of 17.02±3.99cm3; 19.99±5.86cm3; and, 41.23±13.05cm3. It was compared the metrical equivalence of the mean between the two kidneys, to the group with age between 6 and 18 months the parameters showed difference were renal length, renal volume and cortical volume, in other hand to the group older than 18 months it was renal length and medullar length. Comparing different groups was noted that only the left medullar length had equivalent mean in all the groups, it means, the group younger than 6 months, older than 18 months and from 6 to 18 months of age. The results showed direct and positive correlation between corporal weight and age with the linear and volumetric parameters The left corticomedullary correlation was the only of its kind to exhibit significant correlation with the weight (r= -0.365; P value 0.047). The parameters with significant correlation had the regression analysis done, obtained the better line of adjust of the variables. |
