What researchers measure

Primary outcomes

  1. The change of the pain domain of NIH-CPSI score from baseline to 12 weeks after final treatment.

    CP/CPPS-related complaints will be assessed by the the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI). The questionnaire designed to provide symptom scores for patients with chronic prostatitis. The index provides scores on pain (items 1-4), urinary symptoms (items 5-6), and quality of life (items 7-9).Total score ranges from 0 to 35 (higher values represent worse outcome).The index provides a special pain domain (items 1-4) and the score for this domain ranges from 0 to 21.

    Time frame: from baseline to 12 weeks after final treatment.

Secondary outcomes

  1. The change of the pain domain of NIH-CPSI score from baseline to 4 weeks after final treatment.

    CP/CPPS-related complaints will be assessed by the the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI). The questionnaire designed to provide symptom scores for patients with chronic prostatitis. The index provides scores on pain (items 1-4), urinary symptoms (items 5-6), and quality of life (items 7-9).Total score ranges from 0 to 35 (higher values represent worse outcome).The index provides a special pain domain (items 1-4) and the score for this domain ranges from 0 to 21.

    Time frame: from baseline to 4 weeks after final treatment.

  2. The change of total NIH-CPSI score (Q1-9)from baseline to 4 and 12 weeks after final treatment

    CP/CPPS-related complaints will be assessed by the the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI). The questionnaire designed to provide symptom scores for patients with chronic prostatitis. The index provides scores on pain (items 1-4), urinary symptoms (items 5-6), and quality of life (items 7-9).Total score ranges from 0 to 35 (higher values represent worse outcome).

    Time frame: baseline, 4 and 12 weeks after final treatment

  3. The change of urinary symptoms (Q 5-6) and quality of life domains (Q 7-9) of the NIH-CPSI score from baseline to 4 and 12 weeks after final treatment

    CP/CPPS-related complaints will be assessed by the the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI). The questionnaire designed to provide symptom scores for patients with chronic prostatitis. The index provides scores on pain (items 1-4), urinary symptoms (items 5-6), and quality of life (items 7-9).Total score ranges from 0 to 35 (higher values represent worse outcome).The index provides a special urinary symptom domain (items 5-6) and the score for this domain ranges from 0 to 10.

    Time frame: baseline, 4 and 12 weeks after final treatment

  4. The change of quality of life domains (Q 7-9) of the NIH-CPSI score from baseline to 4 and 12 weeks after final treatment

    CP/CPPS-related complaints will be assessed by the the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI). The questionnaire designed to provide symptom scores for patients with chronic prostatitis. The index provides scores on pain (items 1-4), urinary symptoms (items 5-6), and quality of life (items 7-9).Total score ranges from 0 to 35 (higher values represent worse outcome).The index provides a special urinary symptom domain (items 5-6) and the score for this domain ranges from 0 to 10.

    Time frame: baseline, 4 and 12 weeks after final treatment

  5. The change of IIEF-ED score from baseline to 4 and 12 weeks after final treatment

    It will be assessed by International Index of Erectile Function -Erectile Domain (IEF-ED) score. A questionnaire designed to evaluate erectile capabilities. The questionnaire provides a score between 5 and 30.The severity categories are: 1-10 severe ED, 10-16 moderate ED, 17-21 moderate to mild ED, 22-25 mild ED, 26-30 no ED

    Time frame: baseline, 4 and 12 weeks after final treatment

  6. The difference between the LiST and sham group in the change of UPPOINTS phenotype- number of positive domainsfrom baseline to 4 and 12 weeks after final

    Time frame: baseline, 4 and 12 weeks after final treatment
