OBJECTIVE: To evaluate the effects of sacral magnetic stimulation (SMS) on
functional and urodynamic improvement in patients with refractory stress urinary
incontinence (SUI). DESIGN: A sham-controlled, double-blind, parallel study
design with a 4.5-month follow-up. SETTING: A tertiary hospital. PARTICIPANTS:
Women (age, 45-75y) with SUI refractory to first-line management (N=34) were
allocated to either an experimental (n=20) group or a sham (n=14) group.
INTERVENTIONS: The SMS protocol consisted of 5-Hz, 20-minute treatments
administered over the bilateral third sacral roots, with the intensity set at
approximately 70% of the maximal output, for 12 consecutive weekdays. MAIN
OUTCOME MEASURES: Urodynamic assessments and 2 life stress questionnaires,
namely, the Urge-Urinary Distress Inventory (U-UDI) and the Overactive Bladder
Questionnaire (OAB-q), were administered pre- and post-SMS intervention. We
administered the U-UDI (primary outcome measure) and the OAB-q at 3-week
intervals during the follow-up period until 18 weeks after the final
intervention. RESULTS: The experimental group exhibited significant improvements
in both U-UDI and OAB-q scores postintervention (P=.011-.014) and at follow-up
visits (P<.001-.007) compared with the sham group. In addition, significant
increases in bladder capacity, urethral functional length, and the pressure
transmission ratio (P=.009-.033) were noted postintervention. Multivariate
regression analysis revealed that patients with more severe symptoms benefited
more from SMS. A poorer baseline U-UDI score and a shorter urethral functional
length were associated with a greater response to SMS. CONCLUSIONS: Our
observations of a greater response to SMS in patients with more severe SUI than
in those with mild symptoms, as well as the long-term benefits of the treatment,
confirm the efficacy of SMS in treating SUI.
