〔Abstract〕 Chronic prostatitis is one of the common diseases in male urology. The disease of type Ⅲ prostatitis(chronic prostatitis/chronic pelvic pain syndrome) in the classification of prostatitis in the National Institutes of Health(NIH) cannot reflect the nature of the disease, such as unclear etiology and pathogenesis, diverse clinical manifestations, insufficient diagnostic basis, etc. The concept of type Ⅲ prostatitis does not regard the pelvic floor and lower urinary tract as a functional whole. Therefore, the China Chronic Prostatitis Diagnostic Criteria and Efficacy Evaluation Collaborative Group proposed to change the name of type Ⅲ prostatitis to prostatic pelvic syndrome and explore the establishment of symptom-based diagnostic and efficacy evaluation criteria to reflect the nature of the disease and meet the treatment objectives of type Ⅲ prostatitis patients to improve symptoms and improve quality of life. The proposal of new theories and the development of multi-center clinical trials will help urologists deepen their understanding of the prostatic pelvic syndrome and help them to correctly diagnose and treat the syndrome.
