title: The changes of voiding pattern after midurethral sling between pure stress urinary incontinence and stress urinary incontinence with overactive bladder group.
abstract: OBJECTIVE
  The purpose of this study is to compare changes in voiding pattern after midurethral sling surgery (MUS) between the stress urinary incontinence (SUI) group and the overactive bladder (OAB)+SUI group.
  
  
  METHODS
  From January 2008 to February 2011, a retrospective survey was conducted of 225 female patients who had been diagnosed with SUI and undergone MUS. The subjects were divided into the SUI group and the OAB+SUI group. Changes in the overactive bladder symptom score (OABSS) and American Urological Association-Symptom Index (AUA-SI) before and three months after the MUS were compared.
  
  
  RESULTS
  Of the 225 patients, 165 patients (73.3%) were classified as SUI group, and 60 patients (26.7%) were classified as OAB+SUI group. The mean age of the subjects was 54.7 years (range, 31-80 years), and the mean age of patients was 53.9 years (range, 34-80 years), and 56.8 years (range, 31-78 years) in the SUI group and OAB+SUI group. In SUI group, voiding symptom and storage symptom among the AUA-SI were significantly increased (p<0.05). OABSS were slight increased, but was statistically insignificant (p=0.847). In OAB+SUI group, voiding symptom score and OABSS showed a significant increase (p<0.05), but storage symptom score showed an insignificant increase (p=0.790).
  
  
  CONCLUSIONS
  OAB may occur in approximately 18% of SUI patients who undergo MUS surgery, and voiding dysfunctions with deteriorated voiding symptom and storage symptom may also occur. The deteriorated OAB was shown in 45% of SUI patients with OAB after the surgery.
