ABSTRACT: Different pathological events occur to the male urethra, and various surgical protocols have been developed to resolve them. Despite the clinical interest involving the urethra of male dogs in the literature there are only a few reported anatomical investigations. The aim of this study was to create a three-dimensional model of the urethra by means of a corrosion cast to describe and record the structure of the pelvic and penile urethra. These casts of male dog urethras were useful to observe the pelvic and penile portions of the urethra. Morphological details of the inner surface of the urethra remained imprinted on the casts. These replicas can improve understanding of anatomical considerations needed to treat clinical and surgical pathology of the urethra.
