  • Masking: Double

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Electroacupuncture (EA) group
  1. Electroacupuncture therapy (10 sessions in total, 5 per a week, 2 weeks)
  2. BL31, BL32, BL33, and BL34 (total 8 acupoints, bilateral)
  3. 20 minutes duration, middle frequency (30 Hz) of electrical stimulation
  4. conventional treatments permitted
Device: Electroacupuncture (EA)
The EA group receives 10 sessions of EA therapy (5 per a week, 2 weeks). After inserting needles by 5-10 mm (stainless steel, 0.25 mm in diameter and 4.0 mm in length, Dong Bang Acupuncture Inc., Korea) using the Park sham guide tube on the 8 points (BL31, BL32, BL33, and BL34, bilateral sides), de qi response is elicited. The electrical stimulation is then presented for 20 minutes by middle frequency (30 Hz) (STN-111, Stratek, Korea). Conventional treatments (western/traditional herbal medications, rehabilitation, or acupuncture without electro-stimulation for stroke, and western/traditional herbal medications or acupuncture without electro-stimulation for urinary retention) are allowed during the intervention period. The practitioner should have over 1-year clinical experiences.
Sham Comparator: Sham group
  1. Non-penetrating Park sham electroacupuncture treatment (10 sessions in total, 5 per a week, 2 weeks)
  2. BL31, BL32, BL33, and BL34 (total 8 acupoints on the right and left sides)
  3. 20 minutes duration, undelivered electrostimulation of middle frequency (30 Hz)
  4. conventional treatments permitted
Device: Sham electroacupuncture
The patients in sham group receive totally 10 sessions of the sham EA (5 sessions per a week, for 2 weeks). Non-penetrating needles of Park sham device are implemented on the bilateral points of BL31, BL32, BL33, and BL34 (total 8 acupoints). Then, the electro-stimulation is presented for 20 minutes by middle frequency (30 Hz) (STN-111, Stratek, Korea), even though the electrical stimulation is not delivered through the skin. Conventional treatments for stroke and urinary retention along with EAT are not eliminated. It is also necessary for the practitioner with more than 1-year experiences on the clinical field.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change of daily PVR (Postvoid Residual) urine ratios between the baseline and the endpoint
Time Frame: Day 0 (baseline), Day 14(endpoint)
  • daily PVR ratio = daily PVR urine volume / (daily PVR urine volume + self voiding volume)
  • Baseline measurement: daily PVR ratio for 24 hours on the day before the first intervention day Endpoint measurement: daily PVR ratio for 24 hours within 3 days after the last intervention day
  • If more than 7 sessions of EA or sham EA are completed and urinary tract is not infected at the end, then the urine volume is measured on the next day of the last intervention.
  • If more than 7 sessions of EA or sham EA are completed and urinary tract is infected at the end, then the urine volume is measured on the 3rd day of the last intervention after anti-infection treatment is carried out for 48 hours.
Day 0 (baseline), Day 14(endpoint)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Urinary tract infection (UTI)
Time Frame: Day 14(endpoint)
After 7-10 sessions of the EA or sham EA, patients get urinalysis to figure out whether UTI exists. If a patient has UTI, he/she gets antibiotics for 48 hours. When no UTI is found with reexamination of urinalysis, then daily PVR is going to be assessed and included in the final ITT (Intention To Treat) analysis. Otherwise, the data from the patients will be included only in the PP (Per Protocol) analysis.
Day 14(endpoint)
Korean version of Qualiveen Questionnaire (K-QQ)
Time Frame: Day 0 (baseline), Day 14(endpoint)
  • The disease-specific QoL (quality of life) assessment scale for neurogenic bladder
  • Consisting of 30 items and each item is scored by 0 to 4. (The higher score in K-QQ is, the lower QoL of the patients is.)
  • The reliability and validity of K-QQ has been acquired in the previous studies.
  • If more than 7 sessions of EA or sham EA are completed and urinary tract is not infected at the end, then K-QQ is measured on the next day of the last intervention.
  • If more than 7 sessions of EA or sham EA are completed and urinary tract is infected at the end, then K-QQ is measured on the 3rd day of the last intervention after anti-infection treatment is carried out for 48 hours.
Day 0 (baseline), Day 14(endpoint)
Korean version of International Prostate Symptom Scale (K-IPSS)
Time Frame: Day 0 (baseline), Day 14(endpoint)
  • Assessment tool for symptoms in lower urinary tract
  • Consisting of 7 items (0 to 5 scores)
  • If more than 7 sessions of EA or sham EA are completed and urinary tract is not infected at the end, then K-IPSS is measured on the next day of the last intervention.
  • If more than 7 sessions of EA or sham EA treatment are completed and urinary tract is infected at the end, then K-IPSS is measured on the 3rd day of the last intervention after anti-infection treatment is carried out for 48 hours.
Day 0 (baseline), Day 14(endpoint)
Blinding Index (BI)
Time Frame: Day 14(endpoint)
  • Assessment of patients' blinding
  • Patients are asked which group you think you belong to during the study, and they selects one of the options, EA group, sham group, or Not knowing.
Day 14(endpoint)
Frequencies of urination and urinary incontinence
Time Frame: Day 0 (baseline), Day 14(endpoint)
  • Record of the frequencies of urination and urinary incontinence by urinary diary
  • 1 day before the first intervention and another day after the last intervention
  • Mean change between post- and pre-treatments in EA group comparing with the sham group
Day 0 (baseline), Day 14(endpoint)
Adverse events
Time Frame: Every treatment visit (5 times during Day 1~Day 7 & 5 times during Day 8~Day 14)
  • Ask any adverse events after EA or sham interventions and record them in case report forms
  • Evaluate the severity, seriousness, and relevance to the study
Every treatment visit (5 times during Day 1~Day 7 & 5 times during Day 8~Day 14)

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Diabetes mellitus (DM) and benign prostatic hyperplasia (BPH)
Time Frame: Day 0 (baseline)
Check of diabetes mellitus (DM) and benign prostatic hyperplasia (BPH) in medical history.
Day 0 (baseline)
