Background-Prostatitis describes a combination of infectious diseases (acute and chronic bacterial prostatitis), chronic pelvic pain syndrome, and asymptomatic inflammation.Materials and methods-We employed evidence-based methods to review the epidemiology of prostatitis syndromes.Results-The prevalence of prostatitis symptoms could be compared in five studies surveying 10 617 men. Overall, 873 participants met various criteria for prostatitis, representing an overall rate of 8.2%, with prevalence ranging from 2.2 to 9.7%. A history of sexually transmitted diseases was associated with an increased risk for prostatitis symptoms. Men reporting a history of prostatitis symptoms had a substantially increased rate of benign prostatic hyperplasia, lower urinary tract symptoms and prostate cancer. In one study, the incidence of physician-diagnosed prostatitis was 4.9 cases per 1000 person-years. Two studies suggest that about one-third of men reporting prostatitis symptoms had resolution after 1 year. Patients with previous episodes and more severe symptoms are at higher risk for chronic pelvic pain.Discussion-The prevalence of prostatitis symptoms is high, comparable to rates of ischamic heart disease and diabetes. Clinical evaluation appears necessary to verify that prostatitis is responsible for patients' symptoms. Prostatitis symptoms may increase a man's risk for benign prostate hypertrophy, lower urinary tract symptoms and prostate cancer. We need to define natural history and consequences of prostatitis, develop better algorithms for diagnosis and treatment, and develop strategies for prevention.A resurgence of interest in prostatitis has occurred during the last decade. This has been accompanied by a new level of understanding of the epidemiology, morbidity and economic impact of these conditions. Much progress dates from the recognition that infection and inflammation are important in certain prostatitis syndromes. Despite limited information on the causes of other prostatitis syndromes, these conditions can be defined and important treatment studies have been initiated. This article employs evidence-based methods to review the epidemiology of prostatitis syndromes, examines the clinical implications of these data, and outlines areas for future research.

Background-Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) afflicts 2-10% of adult men. Available therapies offer little or no proven benefit. Because acupuncture represents an attractive "natural" therapy, we compared the efficacy of acupuncture to sham acupuncture for CP/ CPPS

Background-In men with chronic prostatitis-chronic pelvic pain syndrome, treatment with alphaadrenergic receptor blockers early in the course of the disorder has been reported to be effective in some, but not all, relatively small randomized trials.

The encouraging long-term response rates show that pulsed magnetic stimulation is an attractive nonsurgical alternative for patients who do not want to undergo surgery.
