Short-term effect of magnetic stimulation added to bladder training in women with idiopathic overactive bladder: A prospective randomized controlled trial.

Abstract

To evaluate the efficacy of magnetic stimulation (MStim) added to bladder training (BT) on incontinence-related quality of life (QoL) and clinical parameters in women with idiopathic overactive bladder (OAB). Seventy-six women with idiopathic OAB were randomized into two groups using the random numbers generator as follows: Group 1 received BT alone (n: 38), and Group 2 received BT + MStim (n: 38). MStim was performed with MStim therapy armchair (Novamag NT60), 2 days a week, 20 min a day, a total of 12 sessions for 6 weeks. Women were evaluated in terms of incontinence severity (24-h pad test), 3-day voiding diary (frequency of voiding, incontinence episodes, nocturia, and number of pads), symptom severity (OAB-V8), QoL (IIQ-7), positive response and cure-improvement rates, and treatment satisfaction (Likert scale) at the baseline and the end of treatment (sixth week). A statistically significant improvement was found in incontinence severity, frequency of voiding, incontinence episodes, nocturia, number of pads, symptom severity, and QoL parameters for two groups at the end of the treatment compared to the baseline values (p < 0.05). At the end of treatment; incontinence severity, incontinence episodes, nocturia, number of pads, symptom severity, and QoL were significantly improved in Group 2 compared to Group 1 (p < 0.05). No difference was found between the two groups in terms of frequency of voiding (p > 0.05). The positive response and cure-improvement rates, and treatment satisfaction were significantly higher in Group 2 than in Group 1 (p < 0.05). MStim added to BT is more effective than BT alone in women with idiopathic OAB.
