Application of buccal mucosal graft to establish a new urination passage in male cats with penile traumatic injury

Abstract

Two male cats were presented with penile part of urethra injury due to dog attacks to the perineum and genitalia area. Chronic wound around a remained penile part of urethra due to the dog bite and perineal area was evident due to urine irritation. The buccal mucosa was harvested and subsequently placed on the granulation tissue of the wound to reconstruct the urinary passage. The buccal mucosal graft completely attached to the skin and urethra without any complications. From the follow-up at 3 months, the cats were able to urinate normally and the skin irritation from urine was resolved. In summary, the buccal mucosa is a good graft source and is suitable for the reconstruction of the urinary passage in severe and complicated cases of penile part of urethra injury in male cats.
