title: Outcome of mid-urethral sling procedures in Korean women with stress urinary incontinence according to body mass index.
abstract: BACKGROUND
  The objective of this study was to determine whether the outcome of mid-urethral sling procedures is influenced by the body mass index of Korean women suffering from stress urinary incontinence (SUI).
  
  
  METHODS
  A total of 285 women, ranging in age from 28 to 80 years (mean 55.4), all of whom were followed up for at least 6 months, were ultimately included in this study. The patients were classified as follows: normal weight, 18.5-23 kg/m2; overweight, 23-27.5 kg/m2; obesity, 27.5 kg/m2 or higher.
  
  
  RESULTS
  We noted bladder perforations in 11 cases (4.9%, 3.8% and 2.2% in the normal weight, overweight, and obesity groups, respectively; P = 0.449). We determined there to be no significant differences among the three groups with regard to cure rate (P = 0.173). The rates of postoperative urinary retention were 9.9% in the normal weight group, 10.1% in the overweight group, and 15.6% in the obesity group (P = 0.396). We determined there to be no significant differences among the three groups with regard to the persistence of urgency (P = 0.312). Seventy-nine patients (27.7%) exhibited symptoms indicative of voiding disorder (hesitancy, poor flow, or sensations of incomplete emptying). The postoperative development of these voiding symptoms was not significantly different among the three groups (P = 0.106).
  
  
  CONCLUSIONS
  Our results demonstrate both the feasibility and the safety of mid-urethral sling procedures for obese Korean women who suffer from SUI. Additional studies, including prospective randomized trials with longer follow-up periods, will be required in order to confirm these findings.
