Abstract：Objective: To investigate the effect of electroacupuncture at Guanyuan and other acupoints on neurogenic bladder (detrusor areflexia type) after spinal cord injury based on ultrasonic guidance technology.Methods: 32 patients with SCI who met the standard were randomly divided into ultrasonic electroacupuncture group (16 cases) and conventional electroacupuncture group (16 cases). The urodynamic tests were performed first, and then the bladder volume was maintained at about 400 mL. CV4, CV3 and bilateral ST29 points were selected for acupuncture with ultrasonic guidance and manual manipulation, respectively. The frequency of electroacupuncture was 40 Hz, the waveform was continuous wave, and the pulse width was 200 μs, and urodynamic parameters, micturition sensation, and contractions of the bladder were observed in real time.Results: Acupuncture guided by ultrasound can accurately and safely locate the needle tip to the bladder muscle layer. In the ultrasonic electroacupuncture group, there was a significant sense of urination during electroacupuncture, 11 patients had slight bladder contraction, and all patients had significant electrical stimulation signals around the anus. There was a significant difference compared with the conventional electroacupuncture group (P<0.05). Pdetmax and Qmax did not change significantly in the two groups before and after electroacupuncture, and there was no significant difference between the two groups (P>0.05). Conclusion:Ultrasound guided electroacupuncture can safely and effectively improve bladder micturition function of patients with detrusor areflexia bladder after incomplete SCI.
