title: Single-incision sling system as primary treatment of female stress urinary incontinence: prospective 12 months data from a single institution.
abstract: OBJECTIVE
  To investigate the success and complication rates for Mini-Arc(TM) single incision sling in the treatment of female stress urinary incontinence (SUI).
  
  
  METHODS
  A total of 119 female patients with pure SUI were enrolled in a prospective study. From these, 105 were available with a minimum follow-up of 6 months and a mean follow-up of 12 months. Success, as determined by patient- reported outcomes, and complication rates, as well as impact of learning curve, body mass index (BMI), intrinsic sphincter deficiency (ISD), incontinence severity and age were investigated.
  
  
  RESULTS
  Cure rate was 80% and improvement rate was 11%. Pain intensity was minimal on a visual analogue scale and transient urinary retention occurred in three patients, one requiring sling section. De novo urgency was reported by 6% of women. Severe incontinence was less likely to be cured: 70% if >5 pads per day (ppd); 94% if <2 ppd; 94% if 2-4 ppd, P < 0.05). There was no difference in success rates between the first 50 and the last 50 patients. BMI, ISD and age also did not influence success rate.
  
  
  CONCLUSIONS
  Mini-Arc™ attained high success rates at 1 year follow-up. The procedure was easy to learn and was associated with very low and mild morbidity. Severe incontinence was identified as a risk factor for failure.
