How often does detrusor overactivity cause urinary leakage during a stress test in women with mixed urinary incontinence?

INTRODUCTION AND HYPOTHESIS: The study examined how often detrusor overactivity (DO) causes leakage during a stress test in women with mixed urinary incontinence (MUI) and whether there are differences between those who do and those who do not have DO during the stress test.
METHODS: A retrospective study was performed in 100 women who had an ambulatory urodynamic recording done where bladder, urethral, and vaginal pressures, and leakage were recorded. The stress test consisted of 20 jumping jacks and three forceful coughs.
RESULTS: All the women leaked during the stress test: five due to simultaneous stress test and DO, 87 due to the stress test only, and eight during the stress test as well as due to DO before or after the stress test.
CONCLUSIONS: During the stress test, 5 % of women with MUI leaked due to the coughs and jumps and simultaneous DO. Women in whom DO was detected had significantly higher Urgency Incontinence Index and leakage during the 24-h pad test.
