Detailed Description
Stress urinary incontinence (SUI) mainly refers to the involuntary leakage of urine when abdominal pressure increases, such as sneezing, coughing, laughing or exercise. According to epidemiological studies, the global median prevalence of female urinary incontinence is 27.6% (4.8%-58.4%), of which SUI accounts for more than 50%. Previous study have demonstrated that acupuncture intervention can reduce the urine leakage in pad test, decrease the ICIQ-SF score, so as to help the patients alleviate the symptoms and improve their quality of life. This multicenter randomized controlled trial set 3 groups. Patients will receive 3 different applications of acupoint combinations so that the optimization of acupuncture treatment of female SUI will be find.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Sacral acupoints group (Sacral group) Participants will receive sacral acupoints combination treatment at bilaterally Huiyang(BL35) and Zhongliao(BL33) with prone position during the whole treatment course. |
Device: Sacral acupoints acupuncture
Before treatment, the participants will be asked to go to the toilet. All treatments will be performed after skin disinfection. As acupuncture needles are inserted, all points will be lifted, twisted, and stabbed to activate the sensation of de qi. The electroacupuncture stimulation lasted for 30 minutes with a continuous wave of 50 Hz and a current intensity of 1 to 5 mA (preferably with the skin around the acupoints shivering mildly without pain). Participants will receive three treatments per week (every other day), each lasting 30 minutes, for a total of 18 sessions over the course of 6 weeks. The follow-up sessions are on week 18, 30, 42 and 54. In this group, paired electrodes from the electroacupuncture apparatus were attached transversely to the needle handles at bilateral Huiyang(BL35) and Zhongliao(BL33) .
|
| Experimental: Abdominal acupoints group (Abdominal group) Participants will receive abdominal acupoints combination treatment at unilateral Zhongji(RN3), Guanyuan(RN4) and bilaterally Dahe(KI12) with dorsal position during the whole treatment course. |
Device: Abdominal acupoints acupuncture
Before treatment, the participants will be asked to go to the toilet. All treatments will be performed after skin disinfection. As acupuncture needles are inserted, all points will be lifted, twisted, and stabbed to activate the sensation of de qi. The electroacupuncture stimulation lasted for 30 minutes with a continuous wave of 50 Hz and a current intensity of 1 to 5 mA (preferably with the skin around the acupoints shivering mildly without pain). Participants will receive three treatments per week (every other day), each lasting 30 minutes, for a total of 18 sessions over the course of 6 weeks. The follow-up sessions are on week 18, 30, 42 and 54. In this group, paired electrodes from the electroacupuncture apparatus were attached to the needle handles respectively at Zhongji(RN3) and one side of Dahe(KI12), as well as Guanyuan(RN4) and another side of Dahe(KI12).
|
| Experimental: Alternating acupoints group (Alternating group) Participants will receive treatment of sacral acupoints combination and abdominal acupoints combination alternately. (For example, A for the first time, B for the second time, A for the third time, and so on. ) |
Device: Alternating acupoints acupuncture
Before treatment, the participants will be asked to go to the toilet. All treatments will be performed after skin disinfection. As acupuncture needles are inserted, all points will be lifted, twisted, and stabbed to activate the sensation of de qi. The electroacupuncture stimulation lasted for 30 minutes with a continuous wave of 50 Hz and a current intensity of 1 to 5 mA (preferably with the skin around the acupoints shivering mildly without pain). Participants will receive three treatments per week (every other day), each lasting 30 minutes, for a total of 18 sessions over the course of 6 weeks. The follow-up sessions are on week 18, 30, 42 and 54. The application of electroacupuncture is the same as Sacral group and Abdominal group.

Outcome Measures
Primary Outcome Measures
- The change of urine leakage measured by the 1-hour pad test [Week 6]
Quantity of fluid loss will be measured by 1-hour pad test, compared with the baseline (week 0).
Secondary Outcome Measures
- The change of mean episodes of urinary incontinence in 72 hours [Week 4, 6, 18, 30, 42 and 54]
The mean episodes of urinary incontinence in 72 hours based on '72 hours bladder diary', comparing the value at week 4, 6, 18, 30, 42 and 54 with the baseline(week 0).
- The change of International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) [Week 4, 6, 18, 30, 42 and 54]
ICIQ-SF is a brief instrument used to assess the frequency of incontinence, the volume of incontinence, as well as the impact of life quality). The value will be recorded at week 4, 6, 18, 30, 42 and 54, compared to that at baseline(week 0).
- Severity of SUI according to '72 hours bladder diary' [Week 4, 6, 18, 30, 42 and 54]
The severity of SUI will be rated according to the amount of UI in usual conditions without extreme activities like severe cough, strenuous exercise or carrying heavy loads in the past 72 hours. Definition: mild(several drops of leakage);moderate(leak that soaked through underwear); severe(leak that soaked through outerwear). In case that participants worn urinal pads, the severity of SUI will be graded as follows. Mild(several drops of leakage); moderate(soaked urine pads in patches by several leakages); severe(soaked urine pads in patches by one leakage). The most severe degree of urine leakage in patient's 72 hours bladder diaries over the assessment period will be selected as the severity of SUI for analyses.
- Participant Self-evaluation of Therapeutic Effects [Week 4, 6, 18, 30, 42 and 54]
No help=0; Small help=1; Medium help=2; Great help=3
- The number of patients who used other treatment for SUI [Week 18, 30, 42 and 54]
Compare the number of patients who used other specialty therapy for SUI during the study between 3 groups.
- Bladder neck mobility by pelvic floor ultrasonography [Week 6]
Bladder neck mobility will be observed both at rest and during a Valsalva maneuver by pelvic floor ultrasonography. The result can be measured from the ultrasonic image.

- Incidence of adverse events [Week 1-6]
Observe the incidence of adverse events during the treatment.
- Evaluation of discomfort during treatment [Within 5 minutes after the first and ninth acupuncture treatment]
Visual analog scale (VAS) will be used to evaluate the degree of discomfort during treatment. The scale ranging from 0 to 10cm, with 0cm indicating no discomfort and 10cm indicating severe discomfort. Evaluation time: The average value of the first and ninth acupuncture treatments was taken within 5 minutes after the end of the two treatments. If the VAS value is missing in one of the cases, another is taken as the result.
- Patient acceptability evaluation [Within 5 minutes after the first and ninth acupuncture treatment]
0=very difficult to accept, 1=slightly difficult to accept, 2=acceptable, 3=easy to accept, 4=very easy to accept. Evaluation time: The average value of the first and ninth acupuncture treatments was taken within 5 minutes after the end of the two treatments. If the VAS value is missing in one of the cases, another is taken as the result.
