title: Twenty-minute pad test: comparison of infusion of 250 ml of water with strong-desire amount in the bladder in women with stress urinary incontinence.
abstract: OBJECTIVE
  The objective was to compare the sensitivity of the 20-min pad test by infusion of 250 ml of water with the strong-desire amount in the bladder in women with stress urinary incontinence (SUI).
  
  
  METHODS
  Eighty-three women with SUI were enrolled between November 2005 and January 2006. The 20-min pad test by infusion of 250 ml of water was performed before urodynamic study (UDS). The strong-desire amount pad test was done after UDS. The results were analyzed by Pearson's chi(2) and Wilcoxon's signed-rank tests.
  
  
  RESULTS
  The sensitivity by infusion of the strong-desire amount was better than infusion of 250 ml of water in the 20-min pad test (P<0.001). In the quantitative study, the two pad tests had fair agreement and the pad weight results of the infusion of the strong-desire amount were statistically higher than the infusion of 250 ml of water (P=0.0004).
  
  
  CONCLUSIONS
  The infusion of the strong-desire amount had better sensitivity measured by the 20-min pad test in women with SUI compared with infusion of 250 ml of water in the bladder.
