Objective To examine the clinical efficacy of modified decoction of Guizhi Fuling Wan（ MDGFW）combined with Xiyanping acupoint injection on quinquagenarian benign prostatic hyperplasia（ BPH） of turbidity stasis blocking syndrome. Methods Totally 100 BPH patients were randomly divided into a treatment group and a control group

50 cases in each group. The control group was given MDGFW orally

and the treatment group was added with acupoint injection of Xiyanping. The two groups were treating for four courses and 15 days was a course. The clinical efficacy

the international prostate symptom score（ IPSS）

prostate volume and the maximum flow rate（ Qmax） were observed after all treatments. Results Among the 50 cases of the treatment group

34 cases were markedly improved（68%）

12 cases effective（ 24%） and 4 cases ineffective（ 8%）. The total effective rate was 92. 00%.While in the 50 cases of the control group

22 cases were markedly improved（44%）

10 cases effective（20%）

18 cases ineffective（36%） with a total effective rate 64%. The total effective rates showed significant different（ P <0. 05） and the efficacy in treatment group was supeior to that in the control group. Compared with pre-treatment

the IPSS grades and prostate volume were significantly decreased and Qmax was markedly improved（ P < 0. 05） in the treatment group. There were no significant differences of the three indexes after treatment in the control group（ P >0. 05）. The three indexes were all significantly improved in the treatment group than those in the control group（ P <0. 05）. Conclusion MDGFW combined with Xiyanping acupoint injection could significantly improve the clinical symptoms

shrink the prostate volume and quicken the urinary flow rate in BPH patients.
