Penile amputation and pre-scrotal urethrostomy in a male guinea pig (Cavia porcellus)

Male guinea pigs (Cavia porcellus), especially older animals, are prone to urethritis and posthitis. Severe, chronic balanoposthitis/posthitis can result in fibrosis, localised infection and the deposition of mineralised plaques in the prepuce. Severe cases may require surgical intervention, such as penile amputation and urethrostomy, to achieve resolution.
