- Registration Number
- NCT03787654
- Brief Summary
The study is to determine the effect of electroacupuncture in female patients with urgency-predominant mixed urinary incontinence. A three-arm non-inferior randomized controlled trial (RCT) using electroacupuncture, sham electroacupuncture and solifenacin with a total sample of 282 is proposed.
The hypothesis is that the improvement (difference in number of urgency urinary incontinence episodes between baseline and 12-week evaluation) in the electroacupuncture group would be 50% or less of the difference in the improvement between the Solifenacin and the sham electroacupuncture groups.
- Detailed Description
Mixed urinary incontinence (MUI) features complaint or involuntary loss of urine associated with urgency and also with effort or physical exertion or on sneezing or coughing. It is regarded as urgency-predominant mixed urinary incontinence (UMUI) when sudden sensation of voiding accompanied by uncontrolled incontinence domains the symptoms. UMUI can bring shame and inconvenience to patients.
As first-line medicine for urge-predominant urinary incontinence, Solifenacin can reduce urgency urinary incontinence episodes in 24 hours. However, the side effects tend to bring about poor compliance among patients.
Acupuncture might be effective in treating UMUI. Previous research indicated that electroacupuncture might be noninferior to pelvic floor muscle training plus Solifenacin in reducing the urgency incontinence episodes of UMUI women. However, that study didn't focuse on UMUI exclusively, thus unable to decide whether electroacupuncture is effective in the treatment of UMUI.

- Primary Outcome Measures
Name Time Method Change of urgency urinary incontinence episodes in average 24 hours from baseline based on 3-day voiding diary. week 12 3-day voiding diary is a reliable objective method to quantify the incontinence episode frequency and are a sensitive measurement to monitor the treatment response. In voiding diary, voiding episodes, urgency episodes, incontinence episodes, the volume drunk and the pads consumed are all recorded.
- Secondary Outcome Measures
Name Time Method Proportion of subjects with complete resolution of urgency urinary incontinence episodes in average 24 hours based on 3-day voiding diary. week 4, week 8, week 12, week 24, week 36 3-day voiding diary is a reliable objective method to quantify the incontinence episode frequency and are a sensitive measurement to monitor the treatment response. In voiding diary, voiding episodes, urgency episodes, incontinence episodes, the volume drunk and the pads consumed are all recorded.
Change of International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI-SF ) score from baseline. week 4, week 8, week 12, week 24, week 36 ICIQ-UI-SF was a questionnaire developed by the International Consultation on Incontinence to evaluate the severity of incontinence and impact to QoL in the past four weeks. It contains four items: frequency, amount of leakage, impact of UI on QoL and a separate item to indicate the cause of incontinence. The score was the sum of the first three items, providing a total score ranging from 0 to 21 with a higher score indicating worse symptoms and greater impact on QoL.
