Overview
Brief Summary
This trial aims to evaluate the efficacy and safety of transcutaneous auricular vagus nerve stimulation (taVNS) for moderate to severe chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). This study is a prospective, randomized, controlled trial. A total of 68 patients with CP/CPPS will be recruited. After baseline assessment, the patients will be randomized into taVNS group (n = 34) and sham-taVNS group (n = 34). The intervention of two group will last for 4 weeks with a 8-week follow-up period after the treatment. The National Institutes of Health chronic Prostatitis Symptom Score index (NIH-CPSI), International Prostate Symptom Score Scale (IPSS), European quality of Life-5 Dimensions Questionnaire (EQ-5D), self-rating anxiety Scale (SAS) and self-rating depression scale (SDS) will be assessed. The adverse events during the whole study will be recorded detailedly.

Outcomes
Primary Outcomes
Change from baseline in National Institute of Health Chronic Prostatitis Symptom Index(NIH-CPSI) total score at week 4
Time Frame: Baseline, week 4
The NIH-CPSI scale scores range from 0 to 43, with higher scores indicating more severe symptoms. The NIH-CPSI total score will be recorded once a week during the treatment period.
Secondary Outcomes
- The change from baseline in Self-rating Anxiety Scale (SAS) at week 4, 8 and 12(Baseline, week 4, 8 and 12)
- Change from baseline in National Institute of Health Chronic Prostatitis Symptom Index(NIH-CPSI) total score at week 8 and week 12(Baseline, week 8 and 12)
- The change from baseline in the Self-rating Depression Scale (SDS) at week 4, 8 and 12(Baseline, week 4, 8 and 12)
- The changes from baseline of NIH-CPSI pain score, urinary score and quality of life score, respectively at week 4, 8 and 12(Baseline, week 4, 8 and 12)
- Proportion of responders at week 4, 8 and 12(Baseline, week 4, 8 and 12)
- The change from baseline in International Prostate Symptom Score (IPSS) score at week 4, 8 and 12(Baseline, week 4, 8 and 12)
- The change from baseline in EuroQol Five Dimensions Questionnaire (EQ-5D) at week 4, 8 and 12(Baseline, week 4, 8 and 12)
