Primary Outcome Measures:
  • Sensitivity to identify SUI in women with a history of SUI and specificity to not identify SUI in healthy women without a history of SUI [ Time Frame: Study Day 1 ]

Secondary Outcome Measures:
  • Positive predictive value (PPV) and negative predictive value (NPV) of the IRCT administered with urodynamic testing [ Time Frame: Study Day 1 ]
  • Urodynamic parameters after IRCT and VCT in normal healthy women and women with a history of SUI [ Time Frame: Study Day 1 ]

Enrollment: 180
Study Start Date: December 2008
Study Completion Date: July 2009
Primary Completion Date: July 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions

Drug: IRCT
Up to two administrations of the IRCT during a single cough testing session
Experimental: 2
Voluntary Cough Test (VCT) followed by Induced Reflex Cough Test (IRCT)
Drug: IRCT
Up to two administrations of the IRCT during a single cough testing session
