OBJECTIVETo study the clinical effects of the modified formula of Bazhengsan on the urination symptoms of chronic prostatis with damp-heat accumulated in the lower jiao.

METHODSA total of 72 chronic prostatitis patients with damp-heat accumulated in the lower jiao were equally randomized to receive the modified formula of Bazhengsan (the trial group) and the primal Bazhengsan (the control group), both for a course of 28 days. Then we observed the changes in the NIH-CPSI scores, scores on Traditional Chinese Medicine (TCM) syndrome, maximum flow rate of urine (MFR) and results of the expressed prostatic secretion test (EPS).

RESULTSAmong the 31 patients of the trial group, 6 were cured, 10 achieved excellent results, 9 got improved, and 6 failed to respond, with a total efficacy rate of 80.6%. While in the control group, 4 were cured, 10 achieved excellent results, 11 got improved, and 7 failed to respond, with a total efficacy rate of 78.1%. Significant improvement was observed in NIH-CPSI scores, TCM syndrome and EPS results in both of the groups (P < 0.05), and the trial group showed significant difference from the control in the improvement of urination symptoms (P < 0.05).

CONCLUSIONModified Bazhengsan is effective in the treatment of chronic prostatis with damp-heat in the lower jiao. It can significantly improve its clinical symptoms, especially urination symptoms.
