Brief 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.

Outcome Measures

Primary Outcomes (1)

  • The proportions of responders of postvoid residual urine (PVR)

    The responder is defined as a participant with a decline of 50% or more from baseline in the PVR volume after spontaneous urination. The PVR volume is the average value of 2 times of the same measurement method with the interval of 6 hours to 3 days.

    week 12

Secondary Outcomes (23)

  • The proportions of responders of postvoid residual urine (PVR)

    week 6

  • The proportions of responders of postvoid residual urine (PVR)

    week 24

  • The proportions of responders of postvoid residual urine (PVR)

Study Arms (2)

Electroacupuncture

EXPERIMENTAL

Bilateral Shenshu (BL23), Ciliao (BL32), Zhongliao (BL33), Huiyang (BL35), and Sanyinjiao (SP6) will be inserted by the needles (0.30 mm in diameter, 75 mm in length or 0.40 mm diameter, 100 mm in length, Hwato Brand, Suzhou Medical Appliance Factory, China).

Other: Electroacupuncture

Sham electroacupuncture

SHAM COMPARATOR

Sham Bilateral Shenshu (BL23), Ciliao (BL32), Zhongliao (BL33), Huiyang (BL35), and Sanyinjiao (SP6) will be inserted by the needles (0.20 mm in diameter, 25 mm in length, Hwato Brand, Suzhou Medical Appliance Factory, China).

Other: Sham electroacupuncture

Interventions

Bilateral BL32 and BL 33 will be inserted to a depth of 70-95 mm with an angle of 20-30° inward and downward into the second and third sacral foramen. Bilateral BL35 will be inserted to a depth of 60-70 mm with a slightly superolateral direction using needles (0.30 mm in diameter, 75 mm in length). Bilateral BL23 and SP6 will be inserted vertically to a depth of 25-30 mm using needles (0.30 mm in diameter, 40 mm in length). The electric stimulators (6805-D electroacupuncture apparatus, Guangzhou Jiayu Medical Company, China) will connect the bilateral BL32, BL33, BL35 and SP 6 and a continuous wave of 10 Hz frequency and an intensity of 5-10 mA for BL 32 and BL 33 and an intensity of 1-5 mA for SP 6 will be applied. The needles will be retained for 60 mins for each treatment session. The participants will be treated three times a week, on alternate days, for 12 successive weeks; 18 sessions for each patient in total.

Electroacupuncture

Sham BL 23, BL32 and BL33 which are 2 cm lateral to BL23, BL33 and BL35 will be inserted by the needles (0.20 mm in diameter, 25 mm in length) to a depth of 2-3 mm. Sham SP 6 which is at the midpoint between the spleen meridian and the kidney meridian will be inserted by the needles (0.20 mm in diameter, 25 mm in length) to a depth of 2-3 mm. The electric stimulators (SDZ-V electroacupuncture apparatus, Suzhou Medical Appliance Factory, China) will connect bilateral BL32, BL33, BL35 and SP 6 and a continuous wave of 10 Hz frequency and an intensity of 0.1-0.3mA will be applied. The needles will be retained for 60 mins for each treatment session. The participants will be treated three times a week, on alternate days, for 12 successive weeks; 18 sessions for each patient in total.
