Abstract
In the pathology of companion animals, three main types of urinary retention are described and encountered: mechanical, spastic and paralytic. The etiopathogenesis of the pathology of paralytic urinary retention, with clinical-pathogenetic consequences that are difficult to identify and remedy therapeutically, mainly recognizes different causes, both neurogenic and traumatic. The traumatic ones are the most common and, depending on the location of the neurological injury, they influence the treatment, the evolution and also the prognosis. The present paper attempts to describe the importance of imaging examinations (both ultrasound and radiographic) in the judicious approach to patients with paralytic urinary retention.
