Abstract

Ultrasound consists of a technique which is performed easily and safe for both the operator and the evaluated animal. This technique has become important in the diagnosis of reproductive disorders and has been widely used in the detection of prostatic and testicular disorders in dogs. Therefore, the present study aimed to evaluate ultrasonographically the reproductive organs of dogs in the city of São Luís, in order to identify the main affections found. For that matter, a total of 116 animals, aged between 5 months and 21 years, males, not neutered, with different weight and races, were divided into three groups according to the age group (FE1 - 39 animals with ages varying From 5 months to 3 years), (FE2 - 37 animals aged 3 to 6 years) and (FE3 - 40 animals aged over 6 years). The most frequent prostatic changes were Benign Prostatic Hyperplasia 22% (n = 26), Prostate Dilated Urethra 6% (n = 7) and Prostate Cyst 5% (n = 6). Regarding testicular disorders, the most common were Testicular degeneration, Microlithiasis and Neoplasia, both for the left and the right testicle. Prostatic affections were more frequent when compared to testicular ones, affecting more FE3 animals. It is concluded that, reproductive changes are more common in the prostate and it affects more frequently adult and elderly animals.
