title: [Urethral diverticulum after substitution urethroplasty. Report of six cases].
abstract: OBJECTIVE
  To expose the pathogenesis, diagnosis and therapeutic options for urethral diverticula appearing after substitution urethroplasty.
  
  
  METHODS
  Over a total of 34 urethroplasties, 20 with pediculated flap and 14 with buccal mucosa, we collected six cases of urethral diverticula/sacculation development. Five of them underwent surgery, and in one case without symptoms we opted for therapeutic abstention.
  
  
  RESULTS
  Currently four patients remain asymptomatic after treatment. The other two are waiting for a second-time urethral closure.
  
  
  CONCLUSIONS
  The development of urethral pseudo-diverticula secondary to stenosis after urethral substitution surgery is not an infrequent complication. For the practice of reconstructive surgery it is important to know that there are techniques to reinforce the resistance of this weakened area of the urethra.
