The investigators plan to conduct this multi-center, three-armed, randomized controlled trial to evaluate the efficacy of electroacupuncture (EA), compared with sham electroacupuncture (SA) and waiting list (WL) on participants with stress-predominant mixed urinary incontinence (MUI).


MUI tends to present with more severe symptoms and put greater burden on the health of individual and economy of society. Current European Association of Urology (EAU) guideline on incontinence recommends to initiate treatment targeted at predominant component of MUI. However, as to whether the interventions for stress urinary incontinence (SUI) can be effectively generalized to stress-predominant MUI, there is still no powerful evidence to support it. It is necessary to seek for interventions specific to stress-predominant MUI. Results of previous studies indicated that acupuncture might help to relieve the incontinence symptoms.
