Beware of the Dog: Traumatic Extrusion of an Artificial Urinary Sphincter Following Blunt Trauma to the Scrotum by a Domestic Animal


Artificial urinary sphincters are commonly used in males with intrinsic sphincter deficiency to improve continence and quality of life. Complications include erosion, mechanical failure and infection. Frequently, a staged approach involving removal of the device, followed by a period of healing and subsequent reinsertion of a new sphincter is required to restore continence. We describe the first case ever reported of traumatic sphincter extrusion following blunt scrotal trauma by a dog and review its clinical features and management.
