Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), is of considerable interest in clinical urology. During the past decade, several new approaches have been made to discover its aetiology and pathophysiological mechanisms and to develop treatment modalities. The aetiology of CPPS has remained unresolved. Bacterial, chemical, urodynamic and immunological aetiologies have been suggested, but none of these has been conclusively proven. The histopathological changes in CP and CPPS are relatively well known, but the pathophysiological changes that lead to chronic inflammation and prolonged symptoms are still poorly understood. This review proposes an additional approach to the pathophysiology of CPPS. The concept of prostate tissue pressure is introduced as an objectively measurable parameter in evaluating the inflammatory process in CPPS. Chronic pain due to neurogenic inflammation and altered mast cell function is also discussed.
