title: Xenograft iterposition in female urethral diverticulum surgery.
abstract: OBJECTIVE
  To describe the use collagen xenograft as adjuvant therapy in the surgical treatment of female urethral diverticulum (FUD) and  to perform a bibliographic review.
  
  
  METHODS
  We performed a surgical approach to remove the diverticulum and repair the remaining dead space with a porcine collagen mesh to avoid fistulas. Monitoring  is done by MRI.
  
  
  RESULTS
  After two years of follow up the patient improved considerably, disappearing the previous symptoms. Follow-up MRI showed no abnormality: There  was no inflammatory reaction or encapsulation of any kind.
  
  
  CONCLUSIONS
  We recognize that the flap or the use of a xenograft are not always necessary, but due to its technical simplicity and effectiveness, it is an important  tool for diverticulum surgery. However, more experience is needed to assess the appropriateness of this method.
