An Efficacy Trial of Electroacupuncture at Points of Bilateral BL33 for Mild and Moderate Benign Prostatic Hyperplasia

An Efficacy Trial of Electroacupuncture at Points of Bilateral BL33 for Mild and Moderate Benign Prostatic Hyperplasia

To evaluate efficacy of BL33 for mild and moderate benign prostatic hyperplasia(BPH).There are trials showing that electroacupuncture on BL33 for mild and moderate BPH is more effective than terazosin. It could reduce the International Prostate Syndrome Score (IPSS) by 6.68±2.84(39.79%),lower urinary symptoms bother of score(BS) and bladder residual urine, and increase maximum urinary flow rate.But the efficacy of BL33 has not been studied. The objective of this study is to evaluate efficacy of BL32 for mild and moderate BPH by comparison with non-acupoint group.

efficacy here means specific effect(or active ingredient) of the point BL33.
