Twenty-Minute Incontinence Test Better Than Longer Test

Statistically significant differences seen between two tests among women with stress urinary incontinence

TUESDAY, Oct. 31 (HealthDay News) -- Twenty-minute pad tests may be even more sensitive than the standard one-hour pad tests for women with stress urinary incontinence, according to a report in the October issue of Urology.

Wen-Yih Wu, M.D., of National Taiwan University Hospital in Taipei, Taiwan, and colleagues compared the two tests in 100 women with stress urinary incontinence from January to March 2005. Women underwent the International Continence Society standard one-hour test before a urodynamic study. After emptying their bladder with a catheter, the women underwent the 20-minute pad test by an infusion of 250 mL of water.

The 20-minute pad test had a sensitivity of 46 percent, compared with 34 percent for the one-hour pad test, the investigators found. The two pad tests had fair agreement and the pad weight results for the one-hour test had larger amounts than those for 20-minute test in the quantitative study.

"Our results have indicated that statistically significant differences in sensitivity exist between the 20-minute pad test and the one-hour pad test in women with stress urinary incontinence," the researchers conclude.
