title: [A multicenter study of mid urethral sling procedures in treatment of female stress urinary incontinence].
abstract: OBJECTIVE
  To investigate the clinical efficacy, surgical indications and postoperative complications of mid urethral sling procedures in treatment of female stress urinary incontinence.
  
  
  METHODS
  A multicenter clinical trial was conducted from April 2002 to April 2008 in five hospitals, 304 cases of genuine stress urinary incontinence and 8 cases of mixed incontinence were included. TVT procedures were carried out in 134 patients, TVTO procedures in 167 patients, Monarc procedures in 11 patients. Perioperative evaluations included: operating time, bleeding volume, and perioperative complications. Operative efficacy was classified into three categories: cure, improved and failure and evaluated before discharge, 3 months after surgery and then every year.
  
  
  RESULTS
  TVT group had longer operating time [(18.5 + or - 9.6) min] and more bleeding volume [(32.2 + or - 12.6) ml] than those in TVTO group [(11.5 + or - 3.1) min, (12.8 + or - 8.5) ml] and in Monarc group [(11.1 + or - 2.6) min, (12.3 + or - 3.5) ml] with P < 0.05. Monarc and TVTO procedures had higher cure rates and improve rates comparing with TVT, but the differences were of no significance. The cure rate (95.7%) in patients with genuine stress incontinence were significantly higher than that in patients with mixed incontinence (37.5%). No significant differences of total intra- and postoperative complications were noted for all of the three procedures. However, bladder injury tended to occur in TVT group and obturator nerve injury and vaginal injury tended to occur in TVTO group. Transient voiding dysfunction and urinary retention were the most common complications.
  
  
  CONCLUSIONS
  Mid urethral sling procedures have excellent clinical outcomes in the treatment of female stress urinary incontinence.
