Uresta bladder support device
The Uresta bladder support device is an intravaginal device indicated for adult women over 18 years of age who experience stress urinary incontinence, including urine leakage during exercise and non-exercise activities such as coughing and laughing. The device is FDA-cleared and licensed by Health Canada. Participants receive the entire kit that includes the three most common sizes which fit 90% of women. Two additional sizes are available in the lab if needed. Participants will be instructed to self-insert the Uresta prior to running, following the manufacturer instructions with researcher guidance as needed. The device aims to provide mechanical support to the urethra and bladder neck to prevent urine leakage during activities that provoke leakage.
- Medical device
Sportex regular tampon
Participants will use a regular absorbency Sportex tampon as a conservative intravaginal support to potentially reduce stress urinary incontinence (SUI) symptoms during running. Participants will be instructed to insert the tampon prior to running into the mid-to-upper vaginal canal while standing or sitting.

About This Trial
The goal of this study is to evaluate the effectiveness of using a regular menstrual tampon or a Uresta pessary to reduce urine leakage associated with running-induced stress urinary incontinence (RI-SUI) in females aged 18 and older. Secondly, the study aims to assess whether either intervention mitigates transient changes in pelvic morphology that occur following a single running bout. Lastly, we aim to evaluate whether participants continue using either intervention during running over the 4-week period following their in-lab participation. The hypotheses are: Hypothesis 1: Among females with RI-SUI, both a tampon and pessary used during a single running bout will reduce urinary leakage symptoms, with greater symptom reduction observed when using the pessary. Hypothesis 2: Participants will report high satisfaction and perceived symptom improvement with both the tampon and pessary, with higher satisfaction and greater improvement reported for the pessary. Hypothesis 3: Both the tampon and pessary will reduce pelvic floor strain incurred by the end of the run, as evidenced by less bladder neck descent, levator plate lengthening, and levator hiatus area increasing relative to that observed when no tampon or pessary is used. Hypothesis 4: A greater proportion of participants will report continued use of the pessary compared to the tampon over the 4-week post-lab period, with higher frequency of use and fewer reported discontinuations. We will perform within-subject comparisons against baseline values to determine the effect of each intervention on RI-SUI symptoms and pelvic organ support. Participants will complete a baseline questionnaire to collect demographic information and assess incontinence severity. They will then attend three laboratory visits within a 10-day period. At each visit, bladder volume will be standardized to between 100 and 200mL, then the participant will undergo three-dimensional (3D) transperineal ultrasound imaging conducted in a standing position. Following imaging, participants will complete a treadmill protocol consisting of 25-minutes running at a moderately difficult pace (rated at 13 - 14 on the Borg Perceiver Rate of Exertion scale), followed by 5 minutes of running at a higher intensity pace. During the run, participants will be asked at 5 minute intervals whether they experienced any urine leakage and to report their perceived amount of leakage. The ultrasound image protocol will be repeated immediately after the run. Participants will be allowed to keep the pessary and will be contacted 4-weeks after the final visit to evaluate whether or not they continued use of a tampon or the pessary, and, if so, we will ask them to report their satisfaction with the intervention(s) they used.
