Study summary

Chronic Urinary Retention (CUR) is defined as a non-painful bladder which remains palpable or percussible after the patient has passed urine by International Continence Society. Postvoid residual urine volume ≥300 mL seems to be widely accepted.

CUR may be caused by a variety of diseases and events including injury of sacral plexus, cauda equina and sacral spinal cord, pelvic floor nerve lesion after pelvic surgery and peripheral neuropathy due to diabetes, etc.. Aforementioned injuries generally affect lower motor neuron causing detrusor underactivity, acontractile detrusor or detrusor areflexia. The prevalence varies by different causes of lower motor neuron lesion. The symptoms of patients are voiding difficulty, bladder distention, bladder without sensation and overflow incontinence.

A multi-center randomized sham-controlled trial will be conducted. The aim of this study is to assess the efficacy and safety of electroacupuncture for urinary function of patients with CUR caused by lower motor neuron lesion.

Other outcomes

  1. The correlation between expectation assessment and the primary outcome

    Expectation assessment will be assessed at baseline; it includes two brief questions to investigate whether patients are confident that acupuncture treatment will help their chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS): "In general, do you believe acupuncture is effective for treating the illness?", "Do you think acupuncture will be helpful to improve your CP/CPPS symptoms?" For each question, participants will choose "Yes", "No", or "unclear" as the answer.

    Time frame: Baseline

  2. The proportions of participants in each response category of the GRA (Global Response Assessment) in the two groups after treatment

    GRA consists of 7 response categories: markedly worsened, moderately worsened, slightly worsened, no change, slightly improved, moderately improved, and markedly improved. We will identify a participant who reports "moderate" or "marked improvement" as a responder.

  5. Patient Blinding assessment

    To test the success of blinding, participants will be asked to reply to the following question at the 12th week of treatment (sessions 35 or 36): "Do you think you have received traditional electroacupuncture in the past weeks?" The participants will be able to choose one of the following options as the answer: "Yes", "No"

    Time frame: week 12

  6. Safety assessment

    Treatment-related adverse events (AEs) include pain, haematoma, localized infection, broken needle, fainting, nausea, headache, dizziness, insomnia, vomiting, or palpitations during or after treatment.
