title: Is modified in situ vaginal wall sling operation the treatment of choice for recurrent genuine stress incontinence?
abstract: OBJECTIVE
  We evaluate objectively the results of a modified in situ vaginal wall sling operation for recurrent genuine stress incontinence and whether it is a substitute for the traditional sling procedure.
  
  
  METHODS
  A total of 23 patients with urodynamically proved recurrent genuine stress urinary incontinence were recruited in this study. Patients were treated with a modified needle urethropexy technique using an island of in situ vaginal skin as a sling to support the bladder neck and urethra. Surgical outcome was evaluated subjectively and objectively at a median of 15 months. A total of 42 patients who underwent a traditional polytetrafluoroethylene sling operation served as controls.
  
  
  RESULTS
  The cure rate of the vaginal wall sling operation was 34.8% by objective assessment, which was lower than that of the traditional sling procedure (88.1%, p <0.05). The subjective success rate demonstrated the same results (vaginal sling 60.9% versus traditional sling 92.9%, p <0.05). The risk factors for operation failure were lower maximal urethral pressure, lower urethral closing pressure, narrow vaginal capacity and previous anterior colporrhaphy or a Stamey operation (all p <0.05). In 3 cases suburethral epithelial inclusion cysts were specific complications of the operation. There was no prolonged urinary retention or urethral erosion.
  
  
  CONCLUSIONS
  Based on our results, we do not believe that the vaginal wall sling operation should be recommended for all recurrent genuine stress urinary incontinence cases and especially not for those with factors predictive of surgical failure. Further studies are needed to investigate and clarify the possible causes of failure.
