Magnetic stimulation for stress urinary incontinence: study protocol for a randomized controlled trial

Area of Science:

• Urology
• Neuromodulation
• Clinical Trials

Background:

• Lack of adequately powered, sham-controlled trials for magnetic stimulation in stress urinary incontinence.
• Need for validated outcomes to establish treatment efficacy.
• Previous studies have limitations that this trial aims to address.

Purpose of the Study:

• To evaluate the efficacy of magnetic stimulation for treating stress urinary incontinence.
• To provide definitive outcome data on this non-invasive therapeutic option.
• To address existing flaws in prior clinical trial designs.

Main Methods:

• Multicenter, randomized, double-blind, sham-controlled parallel-group trial.
• 120 subjects with stress urinary incontinence randomized 1:1 to active or sham magnetic stimulation.
• 8-week treatment protocol (2 sessions/week, 16 sessions total).

Main Results:

• Primary outcome: Improvement in urinary incontinence severity (ICIQ-UI SF) from baseline.
• Secondary outcomes: Cure rates, symptom frequency, pad test results, pelvic floor muscle strength, and quality of life (PGI-I, ICIQ-LUTS-QoL, EQ-5D).
• Safety and cost-effectiveness analyses will also be performed.

Conclusions:

• This trial is designed to provide conclusive evidence on the effectiveness of magnetic stimulation for stress urinary incontinence.
• The study protocol acknowledges and aims to overcome limitations of previous research.
• Results will inform recommendations for this non-invasive treatment modality.
