Paraphimosis

Paraphimosis is inability to completely withdraw the penis into the prepuce. It is most commonly seen in young intact male dogs but has also been reported in castrated male dogs, and rare in cats. The paraphimosis may occur secondary to a hypoplastic prepuce, trauma, a relatively small or stenotic preputial orifice, constriction of preputial hair around the penis, ineffective preputial musculature that cannot effectively retract the penis into the prepuce, hypospadias, neurologic deficits in dogs with posterior paresis, balanoposthitis, large penile tumor, priapism, or may occurs as an idiopathic event. Clinicians can make a diagnosis of the paraphimosis by visual inspection of the penis protruding from the penis. The entire length of the penis should be examined to determine if any other urogenital abnormalities exist. The prognosis is good to guarded for resolution of paraphimosis, depending on the severity and duration of clinical signs.
