Pulsed magnetic stimulation shows efficacy in nonsurgical treatment of incontinence
Women with stress urinary incontinence show encouraging long-term responses to pulsed magnetic stimulation, making it an attractive alternative for patients who do not want to undergo surgery, according to a recent study.
Researchers performed a randomized, double-blind, sham-controlled study in 120 women (≥21 years; 60 participants each in the active and sham arms) with stress urinary incontinence to assess the efficacy of the nonsurgical treatment using pulsed magnetic stimulation. Treatment was done for two sessions per week for 2 months (16 sessions). After 2 months, participants could go for 16 additional sessions regardless of initial randomization.
The primary response criterion was a 5-point reduction in the International Consultation on Incontinence Questionnaire for Urinary Incontinence-Short Form score. The secondary response criteria included objective and subjective cure. Follow-ups were done at months 1, 2, 5, 8 and 14.
At 2 months, 25 participants (75 percent) in the active arm were treatment responders compared with 13 (21.7 percent) in the sham arm (p<0.001). After 2 months, 24 women (40 percent) in the active arm and 41 (68 percent) in the sham arm opt for additional active pulsed magnetic stimulation.
At 14 months, those who received 32 sessions of active pulsed magnetic stimulation had the highest percentage of treatment responders (18/24 or 75.0 percent), followed by those who received 16 sessions (26/36 or 72.2 percent and 28/41 or 68.3 percent) and those who did not receive any active pulsed magnetic stimulation (4/19 or 21.1 percent; p<0.001).
“Despite significant differences in success rates between surgical and nonsurgical treatments for female stress urinary incontinence, a few cross-sectional surveys showed that most patients still prefer the latter,” researchers said.
