An Efficacy Trial of Electroacupuncture at Points of Bilateral BL33 for Mild and Moderate Benign Prostatic Hyperplasia
Condition: Benign Prostatic Hyperplasia (BPH)
MeSH terms: Prostatic Hyperplasia; Hyperplasia
Intervention: needle
Intervention description: For the acupoint group,needle on bilateral BL33 60-80mm with a 45°angle. A feeling of soreness and distension will be felt when needling into the 3rd posterior sacral foramina(S3).Needle with a 100-125 mm long needle without lifting, thrusting or rotating.An electric stimulator is put on.G6805-2 electric stimulator (produced by Shanghai Huayi Medical Instrument Co.Ltd), Sparse-dense wave,20Hz. Stop turning up the current intensity when patients could not stand. 5 times for the first two weeks and 3 times for the last two weeks, 30 min/time.The non-point group take the place 2 cun far from BL33 on the outside horizontally as the non-point and the manipulation methods are the same with those of the point group.
Phase: Phase 2
Study type: Interventional

Summary:

      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.
