Participant Flow

We recruited patients from BPH clinic by newspaper advertisements and notices at clinic site.192 participants entered the study and 92 of them were excluded.It is supposed that patients with IPSS less than 20 would be included.But few mild BPH patients came for the study.The including criteria were changed and patients with IPSS≥8 were included.

Diagnosis and assessment were made by an independent urologist who was uninvolved in the treatment process.Baseline assessments included international prostate symptom score (IPSS), postvoid residual urine (PVR) and maximum urinary flow rate (Qmax).

Acupoint
Needle on bilateral BL33 60-80 mm 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. BL33 is an acupuncture point in the Bladder Meridian.Cun is the unit of measurement used in acupuncture, and 1 cun is defined as the distance across the uppermost joint of the thumb of the person being treated.
Non-acupoint
Take the place 2 cun far from BL33 on the outside horizontally as the non-point. Needle on the non-point for 60-80mm with a 45°angle. A feeling of soreness and distension will be felt .Needle with a 100-125mm long needle without lifting, thrusting or rotating.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.
