We tested the effect of electroacupuncture (EA) on lower urinary tract symptoms (LUTS) in benign prostatic hyperplasia (BPH) patients. A total of 42 BPH patients with LUTS were randomly assigned to either the EA group (EG), received 2 Hz EA for 20 min twice/week for a total of twelve treatments, or a sham EA group (CG), received sham EA. The increase of voiding volume, average flow rate, and maximal flow rate in the EG were  mL,  mL/sec, and  mL/sec, respectively, from baseline value (before EA) using the measurement of an uroflowmetry. These increases were greater than , , and , respectively, in the CG ( , .026, and .030, resp.). The changes of prostate special antigen and international prostatic symptom score were not significantly different between two groups ( , .175, resp.), suggesting the clinical improvement of 2 Hz EA was quite limited to the LUTS of patients with BPH.
