Electro-acupuncture (EA) is a potential treatment for improving bladder function in patients with chronic urinary retention (CUR) caused by lower motor neuron dysfunction. In a pilot study of 30 patients with CUR due to a lower motor neuron lesion, Chinese clinicians carried out 36 sessions of EA over 12 weeks. Electrical stimulation (10 Hz for 30 minutes) was applied with deep needling at bilateral Ciliao BL-32, Zhongliao BL-33 and Huiyang BL-35. Responders were defined as participants with a decline in postvoid residual urine (PVR) volume after spontaneous urination of greater than 50% from baseline. The proportion of responders at weeks 4, 8, and 12 was 6.7 percent, 28 percent, and 43.5 percent, respectively. Decrease in PVR volume compared with baseline was significant at all assessment timepoints. The proportion of patients with severe difficulty with urination (who required assistance with bladder emptying), and with stool retention, also decreased after treatment.
