title: Long-term outcome of transurethral injection of hyaluronic acid/dextranomer (NASHA/Dx gel) for the treatment of stress urinary incontinence (SUI).
abstract: OBJECTIVE
  To investigate the long-term safety and efficacy of transurethral injection of NASHA/Dx gel in women suffering from stress urinary incontinence (SUI).
  
  
  METHODS
  Women with SUI treated with NASHA/Dx gel via the transurethral Implacer device at Mayday University Hospital between November 2002 and December 2003 had long-term outcomes of therapy evaluated.
  
  
  RESULTS
  Eighteen of 21 were followed-up at mean 6.7 years (±SD 0.15). One year after the injection, 11/21 (52.3%) reported improvement. Of the women, 6/21 (28.5%) had a repeat injection and seven (33.3%) women experienced adverse events in the form of periurethral swellings. At 6.7 years, only one of seven women was continent of urine without requiring any further continence procedure, 44.4% were still experiencing SUI symptoms. Nine of 18 (42.8%) had undergone other continence procedures.
  
  
  CONCLUSIONS
  Transurethral injection of NASHA/Dx gel in women with SUI is associated with complications and not effective in the long term.
