Methods： The patients were given acupuncture treatment for 10-30 times; International prostate symptom score （IPSS） and quality of life index （QOL） were used to assess IPSS and QOL scores of the patients before and after treatment. Results： Before treatment IPSS and QOL of the patients were 22.1±6.7 and 4.5±0.6 respectively, and after treatment were 9.1±4.3 and 1.9±1.1 respectively, there were very significant differences in IPSS and QOL between pre-treatment and post-treatment（P〈 0.01）. Conclusion： Acupuncture can relieve the clinical symptoms of prostate hyperplasia and raise the patients＇ quality of life.展开更多
