title: Genital trauma due to animal bites.
abstract: OBJECTIVE
  Animal bites to the external genitalia are rare. We retrospectively evaluated our experience with treating genital trauma caused by animal attacks.
  
  
  METHODS
  We studied the medical records of 10 patients treated in the surgical emergency department at our hospital who presented with genital injury caused by an animal bite from 1983 to 1999. Special attention was given to the severity of injury, surgical treatment, antibiotic prophylaxis and outcome.
  
  
  RESULTS
  Of the 2 men and 8 boys 8 were attacked by dogs, 1 by a horse and 1 by a donkey, respectively. In all cases initial local treatment involved débridement and copious wound irrigation with saline and povidone-iodine solution. Five patients who presented with minimal or no skin loss underwent primary skin closure, including 2 in whom urethral lacerations were surgically repaired. There was moderate to extensive tissue loss in 5 patients, including degloving penile injury in 2, traumatic spermatic cord amputation in 1, complete penile and scrotal avulsion in a 5-month-old infant, and partial penectomy in 1. Reconstructive procedures provided satisfactory cosmetic and functional results in 8 cases. Antibiotic prophylaxis was administered in all patients and no infectious complications developed.
  
  
  CONCLUSIONS
  Animal bite is a rare but potentially severe cause of genital trauma and children are the most common victims. Morbidity is directly associated with the severity of the initial wound. Because patients tend to seek medical care promptly, infectious complications are unusual. Management involves irrigation, débridement, antibiotic prophylaxis, and tetanus and rabies immunization as appropriate as well as primary wound closure or surgical reconstruction. Good functional and cosmetic results are possible in the majority of cases.
