Study Arms:
- Intravaginal Pessary (Type: EXPERIMENTAL): Pessary restores continence by stabilization of the proximal urethra and urethrovesical junction, facilitating pressure transmission to the proximal urethra.
- Behavioral Therapy (Type: EXPERIMENTAL): Pelvic floor muscle training and exercise which includes strong contraction of the pelvic floor muscles to prevent incontinence by occluding the urethra and regular practice can improve pelvic muscle support.
- Pessary combined with behavioral therapy (Type: EXPERIMENTAL): Combination of the explanations above.

Based on this trial design, predict the completion outcome and termination type (if applicable).
