About this study

Official title: Electroacupuncture for Stress-predominant Mixed Urinary Incontinence: a Three-armed Randomized Controlled Trial

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).

Read the detailed description

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ElectroacupunctureProcedure or surgery

    Also called EA

    BL33 is located in the third posterior sacral foramen; BL35, 0.5 cun (≈10mm) lateral to the extremity of the coccyx; and SP6 posterior to the medial border of the tibia, 3 cun superior to the prominence of the medial malleolus. BL33 will be inserted by needles of 0.30×75mm size at the angle of 45°, inward and downward, till the depth of 60-70mm. BL35 will be inserted by needles of 0.30×75mm size, slightly outward and upward, till the depth of 60-70mm. SP6 will be inserted by needles of 0.30×40mm till the depth of 25-30mm. All the needles will be lifted, thrust and twisted evenly for three times, right after insertion, to induce the sensation of deqi. Electronic acupuncture apparatus (Yingdi KWD 808 I electro pulse acupuncture therapeutic apparatus, Changzhou Yingdi Electronic Medical Device Co., Ltd) will be connected to the three pairs of needles transversally, with continuous wave of 20 Hertz (Hz), electric current of 2-6.5 milliampere (mA) for BL33 and BL35, and 1mA-3.5mA for SP6.

  • Sham electroacupunctureProcedure or surgery

    Also called SA

    Sham BL33 is in the area of 1 cun (≈20mm) horizontally outside BL33; sham BL35, 1 cun (≈20mm) horizontally outside BL35; Sham SP6, in the middle of SP6 and tendons. The three pairs of acupoints will be inserted by needles of 0.30×40mm size to a depth of 2-3mm till the needles can stand still. No manipulations will be conducted, and the sensation of deqi will not be induced. Electronic acupuncture apparatus (Yingdi KWD 808 I electro pulse acupuncture therapeutic apparatus, Changzhou Yingdi Electronic Medical Device Co., Ltd) will be connected to the three pairs of needles transversally, with continuous wave of 20Hz and minimal electric current (ideally at a degree which participant can just percept). In about 30 seconds, the electric current will be turned down, leaving the indicator light and ticking sound on.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of participants with at least 50% reduction of mean 24-hour stress incontinence episode frequency (IEF) from baseline.

    Measured: week 8

Secondary outcomes (12)
  1. Proportion of participants with at least 50% reduction of urinary leakage amount from baseline.

    The urinary leakage amount will be measured by 1 hour pad test.

  2. Change of urinary leakage amount from baseline

    The urinary leakage amount will be measured by 1 hour pad test.

    Measured: week 8

  3. Proportion of participants with at least 50% reduction of mean 24-hour stress IEF from baseline.

    The stress IEF will be documented in 3-day voiding diary.

    Measured: week 4,week 20 and week 32

  4. Change of mean 24-hour IEF from baseline.

    The IEF will be documented in 3-day voiding diary.

    Measured: week 4,week 8, week 20 and week 32.

  5. Change of mean 24-hour stress IEF from baseline

    The stress IEF is documented in 3-day voiding diary.

    Measured: week 4,week 8, week 20 and week 32.

  6. Proportion of participants with at least 50% reduction of mean 24-hour IEF from baseline

    The IEF will be documented in 3-day voiding diary.

    Measured: week 4,week 8, week 20 and week 32

  7. Change of total and sub-score of International Consultation on Incontinence Questionnaire-short form (ICIQ-SF) from baseline.

    ICIQ-SF questionnaire is a validated questionnaire to assess the severity of incontinence symptoms and influence on QoL in the past four weeks. The questionnaire includes items of IEF, urinary leakage amount and general influence on life to be scored. Total number of the score ranges from 1 to 21, with higher scores representing greater severity and 2.52 as minimal clinically important differences.

    Measured: week 4,week 8, week 20 and week 32

  8. Change of total and sub-score of Overactive Bladder Questionnaire short form (OAB-q SF) from baseline

    OAB-q SF is a validated questionnaire used to assess the OAB symptom bother and the health-related quality of life (HRQL) in the past 4 weeks. The domains include coping, concern, sleep and emotional interactions. The scores are transformed to a 0- to 100-point scale, with higher scores indicating severe symptoms and better HRQL.

    Measured: week 4,week 8, week 20 and week 32

  9. Change of mean 24-hour pad consumption from baseline

    The pad consumption will be documented in 3-day voiding diary.

    Measured: week 4,week 8, week 20 and week 32

  10. Proportion of participants with adequate improvement assessed by Patient global impression improvement (PGI-I).

    PGI-I is a global index, with only one item, used to rate the participants' subject perception on symptom improvement. Participants will describe their impression from very much better to very much worse. Adequate Improvement is defined as the response of"much better" or "very much better".

    Measured: week8, week 20

  11. Change of mean 24-hour urgency episodes from baseline

    The urgency episodes will be documented in 3-day voiding diary.

    Measured: week 4,week 8, week 20 and week 32

  12. Change of mean 24-hour micturition episodes from baseline

    The micturition episodes will be documented in 3-day voiding diary.

    Measured: week 4,week 8, week 20 and week 32
