title: Preoperative voiding detrusor pressures do not predict stress incontinence surgery outcomes.
abstract: OBJECTIVE
  The aim of this study was to determine whether preoperative voiding detrusor pressures were associated with postoperative outcomes after stress incontinence surgery.
  
  
  METHODS
  Opening detrusor pressure, detrusor pressure at maximum flow (p (det) Q(max)), and closing detrusor pressure were assessed from 280 valid preoperative urodynamic studies in subjects without advanced prolapse from a multicenter randomized trial comparing Burch and autologous fascia sling procedures. These pressures were compared between subjects with and without overall success, stress-specific success, postoperative detrusor overactivity, and postoperative urge incontinence using independent sample t tests.
  
  
  RESULTS
  There were no clinically or statistically significant differences in mean preoperative voiding detrusor pressures in any comparison of postoperative outcomes.
  
  
  CONCLUSIONS
  We found no evidence that preoperative voiding detrusor pressures predict outcomes in women with stress predominant urinary incontinence undergoing Burch or autologous fascial sling procedures.
