Therapeutic Results of Defined Pollen-Extract in Patients with Chronic Prostatitis or BPH Accompanied by Chronic Prostatitis Therapeutic Results of Defined Pollen-Extract in Patients with Chronic Prostatitis or BPH Accompanied by Chronic Prostatitis

The use of the pollen-extract in the treatment of benign prostatic diseases as BPH and prostatitis has already been described since 1960 and leads to clinical improvement of symptoms and positive changes by objective parameters. In a double-blind study with 61 patients and a simultaneously carried out open examination with 118 patients Leadner (9) stated in the verum-group a normalization of initially pathological palpation findings and leucocytosis of prostatic fluid in 94% of patients with chronic prostatitis who were treated with pollen-extract. 6% of the patients showed unchanged results, aggravations were not observed. In the placebogroup 48% showed normalization, 34% demonstrated an unchanged status and in 18% of the patients the findings were deteriorated. The results of treatment in the open trial revealed only small differences in comparison to therapeutic effects in the verum-group which can be rated as accidental. Takeuchi (10) demonstrated in a clinical study with 25 BPHpatients in stage 1 or 2 under treatment with pollen-extract besides the elevation of peak urine flow rate a significant (p < 0.05) decrease of maximum urethral closure pressure with a corresponding diminished resistance of the prostatic part of the urethra.
