Brief Summary:
The purpose of this study is to assess the effectiveness and safety of acupuncture for treating overactive bladder in adults.

Condition or disease Intervention/treatment Phase
Overactive Bladder Other: Acupuncture Other: Sham acupuncture Phase 2

Detailed Description:

This randomized, controlled trial is aimed to assess the effectiveness and safety of acupuncture in the treatment of overactive bladder (OAB) in adults. Eligible participants will be randomly allocated to acupuncture or sham acupuncture.

To minimize the evaluation bias, the outcome assessors and statisticians will be masked to treatment allocation besides participants.

Arm Intervention/treatment
Experimental: Acupuncture
Participants will receive acupuncture.
Other: Acupuncture
Participants will receive acupuncture, three times per week for eight weeks. The selected acupoints include bilateral BL33, BL35, SP6, and ST36. All acupoints areas have been sterilized before acupuncture. For BL33, a needle (Ф0.40×100mm) will be inserted with an angle of 60° in an inferomedial direction at a depth of 90-100mm. For BL35, the same needle will be inserted with a direction to the ischial rectal fossa at a depth of 60-70 mm deep. For SP6 and ST36, needles (Ф0.30×50mm) will be directly inserted at a depth of 25-30 mm deep. After the needles are inserted, a portable electro-acupuncture machine will be connected to the handles of needles located in BL33 and BL35 to provide the electrical stimulation for 30 minutes with a disperse-dense wave (4/20Hz). All current intensities will be as high as can be tolerated.

Sham Comparator: Sham acupuncture
Participants will receive sham acupuncture.
Other: Sham acupuncture
The sham acupoints will be located at 20 mm outward to BL33, BL35, SP6, and ST36, and the needless will be inserted with a depth of 2 mm. The BL33 and BL35 will not receive any electrical stimulation, though the handles of needles will be connected to the same machine as the acupuncture group, and the parameter setting and course are also the same.




Primary Outcome Measures :
  1. Change in number of micturition episodes per 24 hours [ Time Frame: Before treatment (baseline), 8 week (post-treatment) and 12 week (follow-up) ]
    Assessed by 72 h bladder diary


Secondary Outcome Measures :
  1. Number of urinary urgency episodes per 24 hours [ Time Frame: Before treatment (baseline), 8 week (post-treatment) and 12 week (follow-up) ]
    Assessed by 72 h bladder diary

  2. Number of daytime micturition episodes per 24 hours [ Time Frame: Before treatment (baseline), 8 week (post-treatment) and 12 week (follow-up) ]
    Assessed by 72 h bladder diary

  3. Number of nocturia episodes per 24 hours [ Time Frame: Before treatment (baseline), 8 week (post-treatment) and 12 week (follow-up) ]
    Assessed by 72 h bladder diary

  4. Change in mean volume voided per micturition [ Time Frame: Before treatment (baseline), 8 week (post-treatment) and 12 week (follow-up) ]
    Assessed by 72 h bladder diary

  5. Change in OABSS questionnaire [ Time Frame: Before treatment (baseline), 8 week (post-treatment) and 12 week (follow-up) ]
    Assessed by Overactive Bladder Symptom Score (OABSS) questionnaire. OABSS includes 4 questions about individual symptoms, and the total score ranged from 0 to 15, with higher scores indicating more severe symptoms. The minimal important difference (MID) for the OABSS is 3 points.

  6. Change in OAB-q SF questionnaire [ Time Frame: Before treatment (baseline), 8 week (post-treatment) and 12 week (follow-up) ]
    Assessed by overactive bladder questionnaire short form (OAB-q SF) questionnaire. OAB-q SF includes 6 questions on 6-point Likert-type scales, with the outcomes transformed to a 0-100 point scale in which higher scores indicate more severe symptoms. The minimal important difference (MID) for the OAB-q SF is 11 points.

  7. Urinary NGF/Cr level [ Time Frame: Before treatment (baseline), 8 week (post-treatment) ]
    Measured by human nerve growth factor (NGF) ELISA Kit. NGF/Cr: NGF normalized to urine creatinine (Cr)

  8. Urinary BDNF/Cr level [ Time Frame: Before treatment (baseline), 8 week (post-treatment) ]
    Measured by human brain derived neurotrophic factor (BDNF) ELISA Kit. BDNF/Cr: BDNF normalized to urine creatinine (Cr)

  9. Urinary MCP-1/Cr level [ Time Frame: Before treatment (baseline), 8 week (post-treatment) ]
    Measured by human monocyte chemoattractant protein-1 (MCP-1) ELISA Kit. MCP-1/Cr: MCP-1 normalized to urine creatinine (Cr)
