Dimensões prostáticas ultrassonográficas em cães não castrados

Abstract

It has been evaluated by ultrasonography, the prostate size of 60 dogs, uncastrated and without clinical signs of diseases in this gland, in order to establish standards measures according to age and weight of the animals. The dogs were divided into group 1A, 10 dogs with 1 to 5 years weighing less than 10 pounds; group 1B, 10 dogs with 1 to 5 years weighing 10 to 25 pounds; group 1C, 10 dogs with 1 to 5 years over 25 pounds; group 2A, 10 dogs with 5 to 10 years weighing less than 10 pounds; group 2B, 10 dogs with 5 to 10 years weighing 10 to 25 pounds; group 2C, 10 dogs with 5 to 10 years over 25 pounds, in order to correlate the prostatic size and weight, regardless of race. The length and height were obtained with longitudinal sections, which resulted in an estimate of average prostate size for each size and age studied. The average values of length and height, in inches, for each group, were 1.8 x 1.9 (1A), 2.1 x 2.5 (1B), 2.7 x 3.1 (1C), 1.8 x 1.7 (2A), 3.2 x 3.2 (2B), 3.1 x 3.3 (2C). The results showed a significant positive correlation between prostate size and body weight (p<0.001), which did not occur with age. Equations were constructed in which one can determine the expected length (L = 1.12 +0.04 x weight (kg) + 0.09 x age (years)) and height (H= 1.31 + 0.05 x weight (kg) x age (years)) for prostate according to body weight and age.
