Controversies in chronic abacterial prostatitis/pelvic pain syndrome.

Chronic abacterial prostatitis (or prostatitis Category III according to the National Institutes of Health terminology) is subject to re-evaluation. Organizations such as the International Continence Society, the International Association for the Study of Pain and the European Association of Urology have been involved in a continuous endeavour to design a more accurate taxonomy system. The term prostate pain syndrome (PPS), as a subcategory of chronic pelvic pain syndromes, has recently been suggested as the most relevant.
