Prostatic disorders like benign prostatic hyperplasia, prostatitis, cysts, and neoplasia are common in older male dogs. The objective of the treatment of such disorders is to decrease prostatic size aiming to alliviate their respective symptoms. The aim of the present research work was to evaluate the efficacy of castration in regard to the prostatic size and stromal tissue of healthy dogs. The prostate volume was evaluated by ultrasonography and the measurements performed before (baseline) orchiectomy and at 7, 21, 40 and 90 days after castration. Canine prostatic volumes significantly decreased by 81% in the 90th day after castration. In most of the experimental animals (80%) as much as 50% reduction of the prostate volume has been observed after 15 days of castration, showing that orchiectomy is an efficient therapy to reduce prostatic size. On the other hand, ultra-sonography is a non invasive diagnostic method indicated towards prostatic evaluation.
