[Acupuncture therapy for chronic prostatitis / chronic pelvic pain syndrome and its central neural mechanisms]

Chronic prostatitis / chronic pelvic pain syndrome (CP/CPPS) is one of the common diseases in andrology, with the main clinical symptoms of long-term and repeated pain or discomfort in the pelvic region. Acupuncture has been widely used in the treatment of CP/CPPS-related pelvic pain and discomfort with rapid and long-lasting effects, and its combination with Western medicine can produce an even better effect than Western medicine alone. At present, various theories have been advanced on the action mechanisms of the acupuncture therapy for CP/CPPS, involving immunoregulation, improvement of inflammatory response, and so on, but all fail to give a full explanation. With the development of neuroimaging technology, CP/CPPS patients are found with changes in the structure and function of the brain, and a large number of studies have confirmed the effect of acupuncture in improving the cerebral function and structure of the patients with chronic pain symptoms. This review outlines the advances in the studies of acupuncture therapy for CP/CPPS and its underlying central neural mechanisms, paving the theoretical ground for a deeper insight into the central neural mechanisms of and an optimized protocol for acupuncture treatment of CP/CPPS-related pain symptoms.
