The Effectiveness of Combined Pelvic Floor Muscle Training and Vaginal Oestrogen Therapy in Postmenopausal Women With Stress Urinary Incontinence

The objective of this clinical trial is to investigate whether the combination of pelvic floor muscle training (PFMT) and topical estrogen is more effective in treating stress urinary incontinence (SUI) in postmenopausal women compared to topical estrogen alone. The trial will also analyze factors related to the outcomes of the combined therapy. The key questions this trial aims to answer are: * Does the combination of PFMT and topical estrogen improve symptoms of stress urinary incontinence in postmenopausal women better than topical estrogen alone? * Which factors are associated with the effectiveness of the combined therapy? Researchers will compare the group receiving the combined therapy (pelvic floor muscle training plus topical estrogen) with the group receiving topical estrogen alone to determine whether adding PFMT to estrogen therapy provides additional treatment benefits for SUI in postmenopausal women. Participants will: \- Be randomly assigned to one of two groups: Group 1: Undergo a pelvic floor muscle training (PFMT) program combined with topical estrogen therapy (e.g., vaginal cream/application,...). Group 2: Receive topical estrogen therapy alone (e.g., vaginal cream/application,...). * Follow the assigned intervention protocol for a specified duration. * Attend regular clinic visits for clinical examinations, assessment of incontinence severity, and related measurements. * Monitor and record their incontinence symptoms and the frequency of urine leakage during daily activities.
