Effect of Supervised Pelvic Floor Biofeedback and Electrical Stimulation in Women With Mixed and Stress Urinary Incontinence

Objective: The aim of this study was to compare the symptomatic change in urinary symptom distress before and after treatment with pelvic floor biofeedback and electrical stimulation in women with mixed urinary incontinence (MUI) and stress urinary incontinence (SUI). Methods: We conducted a retrospective cohort study of women who underwent supervised pelvic floor biofeedback therapy and electro-stimulation for the treatment of MUI and SUI. Our primary outcome was change in the Urinary Distress Inventory-6 (UDI-6) score before and after therapy. Results: Overall, a significant drop in UDI-6 score was seen in women with MUI (mean decrease, 29.1 [27.5]; P < 0.001), and a nonsignificant drop was seen in women with SUI (mean decrease, 6.8 [20.3]; P = 0.07) after treatment. Significantly greater change in UDI-6 score from baseline to follow-up was noted in women with MUI compared with those with SUI (P = 0.002). Conclusions: Women with MUI have greater urinary distress symptoms than women with SUI. Both women with MUI and SUI experienced significant improvement in their urinary distress symptoms after pelvic floor biofeedback and electrostimulation.
