Interventions

Electroacupuncture (EA)DEVICE

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 electroacupunctureDEVICE

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.

Outcomes

Primary Outcomes

Change of daily PVR (Postvoid Residual) urine ratios between the baseline and the 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.

Time frame: Day 0 (baseline), Day 14(endpoint)

Secondary Outcomes

Urinary tract infection (UTI)

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.

Time frame: Day 14(endpoint)

Korean version of Qualiveen Questionnaire (K-QQ)

* 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.

Time frame: Day 0 (baseline), Day 14(endpoint)
