Abstract: ObjectiveTo observe the effect of third sacral nerve root electro-acupuncture on acontractile detrusor. Methods84 patients with acontractile detrusor were divided into 2 groups received urethral catheterization alone (control) or electro-acupuncture on third sacral nerve (treatment) respectively. The voiding diary (including urination times, nocturia times and urinary volume) and urodynamics test (including maximum bladder volume, maximum systolic pressure detrusor, the effective time of detrusor contraction, maximum urinary flow rate, average urinary flow rate and residual urine volume) were observed before and 8 week after treatment. ResultsCompared with those before treatment, the urination times, nocturia times and residual urine volume decreased (P<0.05) in treatment group, while maximum systolic pressure detrusor, the effective time of detrusor contraction, maximum urinary flow rate, average urinary flow rate and residual urine volume improved (P<0.05), but the maximum bladder capacity showed no significant difference (P>0.05). ConclusionElectro-acupuncture on third sacral nerve is an effective intervention for acontractile detrusor.
