Orchiectomy to reduce the prostatic size. Experimental study in dogs

Abstract

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.
