title: A long-term study of the effects of the tension-free vaginal tape procedure for female stress urinary incontinence on voiding, storage, and patient satisfaction: a post-hoc analysis.
abstract: OBJECTIVE
  We assessed the long-term effects of the tension-free vaginal tape (TVT) procedure for stress urinary incontinence (SUI) on voiding, storage, and patient satisfaction.
  
  
  METHODS
  This retrospective study examined the records of 134 patients who had undergone the TVT procedure for SUI and were followed up for more than 5 years. Voiding function was evaluated by measuring maximum urinary flow rate (MFR), post-void residual urine volume (PVR), and storage function by using a voiding diary. Patients were asked to describe their satisfaction with the operation.
  
  
  RESULTS
  MFR was lower at 1 month compared with the preoperative level, but had recovered to preoperative levels by 5 years postoperatively. However, some patients with >50%, 25-50%, and <25% decreases in the MFR at 1 month postoperatively showed a decrease in the MFR of >50% at 5 years. PVR increased over the 5 postoperative years. Of the patients with urgency and urgency incontinence, 43.8% and 48.1% showed improvement, respectively, whereas new patients developed postoperatively. Thus, the total number of patients with urgency or urgency incontinence remained similar over the 5 years. In those with a changed voiding pattern, patient satisfaction was negatively affected by de novo urgency and urgency incontinence and decreased MFR.
  
  
  CONCLUSIONS
  Any obstructive effect of the TVT procedure diminished over time in most patients, although a decrease in the MFR was sustained in some patients. With regard to overactive bladder symptoms, some patients were cured and some patients complained of de novo symptoms. The most major factor affecting patient satisfaction was de novo urgency.
