External electrical stimulation compared with intravaginal electrical stimulation for the treatment of stress urinary incontinence in women: A randomized controlled noninferiority trial.

The NMES significantly improved objective and subjective measures of SUI, although statistical noninferiority was not established. The NMES was well tolerated and associated with fewer urinary tract infections than the comparator. The NMES provides a safe, clinically effective, conservative treatment option for female SUI and a low-risk alternative to intravaginal devices.
