Renal failure in a patient with an amputated penis by a dog bite.

Dog bites have been characterized as ‘a major public health problem’ and ‘a tremendous injury problem’ [1,2]. Although reports include dog bites of the penis and scrotum, urethral stricture by a dog bite has not been previously reported. We describe a patient with an amputated penis by a dog bite, in whom a long evolution urethral stricture caused renal failure. To our knowledge, this is the first case of renal failure following the amputation of penis by a dog bite over a time span of 60 years.
