Clinical research of electroacupuncture combined with transperineal injection of BTX-A for neurogenic bladder after spinal cord injury / 中国针灸

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the clinical efficacy of electroacupuncture (EA) combined with transperineal injection of botulinum toxin-A (BTX-A) on neurogenic bladder caused by spinal cord injury.</p><p><b>METHODS</b>One day af ter surgery, 35 cases of spinal cord injury accompanied with neurogenic bladder were randomly divided into a BTX-A plus EA group (20 cases, group A) and a BTX-A group (15 cases, group B). The two groups were both treated with regular rehabilitation training of bladder function and injection of 200 IU (4 ml) BTX-A through perineum external urethral sphincter; the group A was additionally treated with EA at Zhongji (CV 3), Guanyuan (CV 4), Shenshu (3BL 23), Huiyang (BL 35) and Baliao (Shangliao (BL 31), Ciliao (BL 32), Zhongliao (BL 33), Xialiao (BL 34)), once a day, 40 min per treatment. The treatment was given 6 times per week for 4 weeks. The urination status in two groups before and after treatment was observed, and urodynamics examination and urethral pressure test were also made.</p><p><b>RESULTS</b>After 4-week treatment, mean times of urinary incontinence, mean urethral catheter output, pressure of bladder and volume of urinary incontinence were all improved in two groups (all P<0.05), which were more significant in the group A (all P<0.05). The residual urine, maximum bladder capacity, maximum urethral closure pressure and maximum urine flow rate were all improved in two groups after treatment (all P<0.01); the improvement of residual urine, maximum bladder capacity, maximum urethral closure pressure in the group A was more significant than that in the group B (all P<0.05).</p><p><b>CONCLUSION</b>Electroacupuncture com bined with transperineal injection of BTX-A could effectively improve the urination dysfunction in patients with neurogenic bladder after spinal cord injury.</p>
