Objective To observe the effect of fire needling on prostate symptoms

quality of life

average daily number of nightly urination

urine flow rate and prostat volume in patients with mild to moderate benign prostatic hyperplasia（BPH） of kidney yang deficiency. Methods A total of 60 patients with mild to moderate BPH of kidney yang deficiency were randomly divided into an observation group（30 cases

3 cases dropped off） and a control group（30 cases

4 cases dropped off）. The observation group was treated with fire needling at Guanyuan（CV 4）

Shuidao（ST 28） and Qugu（CV 2） twice a week（2-3 d interval between each treatment）

continuous treatment for 4 weeks. The control group received lifestyle advice and education

once a week for 4 weeks. In the two groups

the international prostate symptom score（IPSS）

the quality of life（QoL） score and the average daily number of nightly urination were observed before treatment

after treatment and during the follow-up of the 4th week; the urinary maximum flow rate（Qmax）

the average flow rate（Qave）

and the prostate volume were assessed before and after treatment in the two groups. The safety was observed in the observation group. Results After treatment and during follow-up

the IPSS scores

QoL scores

and the average daily number of nightly urination in the observation group were decreased compared with those before treatment（P<0.05）

and those in the observation group were lower than the control group（P<0.05）. After treatment

there was no significant difference in Qmax

Qave and prostate volume between the two groups and within the each group（P>0.05）. There were no fire needling-related adverse reactions

and no obvious abnormality was found in urine routine and coagulation function tests before and after treatment in the observation group. Conclusion Fire needling can improve lower urinary tract symptoms and quality of life

reduce frequency of nightly urination in patients with mild to moderate BPH of kidney yang deficiency

and has good safety.
