Outcomes of different protocols of pelvic floor physical therapy and anti-cholinergics in women with wet over-active bladder: A 4-year follow-up

Aims: We investigated the 4-year outcomes of three protocols of pelvic floor physical therapy and anticholinergic drug in women with wet over-active bladder (OAB). Methods: One hundred and sixty-four women were randomly allocated to one of four interventions: drug therapy (DT), bladder training (BT), pelvic floor muscle training (PFMT), or combined pelvic floor rehabilitation (CPFR) that includes BT, PFMT, and behavioral advice. The active treatment in each group lasted 3 months. Of the 132 women who completed a 1-year follow-up, 120 women (90%) responded to our questionnaires and therefore were included in this study. Outcome measures were the number of voids per day, number of urgency urinary incontinence (UUI) episodes per week, completely dry rate and Incontinence Quality of Life questionnaire (I-QOL) at 4 years. Results: After 4 years of follow-up, the outcome measures improved significantly and equally in all four groups. The median number of UUI episodes/week dropped by 3, 1, 2, and 2 in the DT, BT, PFMT, and CPFR groups, respectively (P = ns). The dry rates were 25%, 31%, 44%, 34% in the DT, BT, PFMT, and CPFR groups, respectively (P = ns). I-QOL scores improved significantly in all four groups. Conclusions: Women who suffer from wet-OAB may experience the same degree of long-term improvement following various pelvic floor physical therapy protocols as they would from drug therapy.
