Abstract

PURPOSE
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.
MATERIALS AND 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.

• 

  FIG. 1 Preoperative and postoperative changes of American Urological Association-Symptom Index (AUA-SI) in patients with stress urinary incontinence (SUI). All of total AUA-SI, voiding symptom score and storage symptom score were all statistically significantly increased after the SUI group compared to before surgery.

• 

  FIG. 2 Preoperative and postoperative changes of overactive bladder symptom score (OABSS) in patients with stress urinary incontinence (SUI). OABSS was little bit increased after surgery in SUI group compared to before surgery, but there was no statistically significant difference.

• 

  FIG. 3 Preoperative and postoperative changes of American Urological Association-Symptom Index (AUA-SI) in patients with overactive bladder (OAB)+stress urinary incontinence (SUI). Total AUA-SI, voiding symptom scores were significantly increased after the surgery for OAB-SUI group compared to before surgery. Storage symptom score also was increased, but there was no statistically significant difference.

• 

  FIG. 4 Preoperative and postoperative changes of overactive bladder symptom score (OABSS) in patients with overactive bladder+stress urinary incontinence (OAB+SUI). OABSS was statistically increased after the surgery for OAB+SUI group compared to before surgery.
