The cause of prostatitis, the first thing to be clear is that prostatitis is divided into acute prostatitis and chronic prostatitis: first, for acute prostatitis, usually caused by bacteria, such as bloodstream bacteria infecting the prostate, causing local inflammation, infection, and even septicemia, can also be retrograde from the urethral orifice bacteria, into the prostate to cause inflammation. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. For non-bacterial prostatitis etiology is more complex, currently the main etiology may be pathogenic infection or inflammation, or abnormal pelvic floor neuromuscular activity, immune abnormalities and other joint results caused. The first is the infection of pathogens, sometimes the routine bacterial examination may not be able to detect the pathogens, but there may be special pathogens, such as anaerobic bacteria, metaplasia, chlamydia, mycoplasma infection are possible; second, urinary dysfunction, certain factors cause excessive contraction of the urethral sphincter, resulting in bladder outlet obstruction and residual urine formation, resulting in urine reflux into the prostate; third. The first of these is the fact that the actual person who is in a position to get the job done is the person who is in a position to get the job done. The first of these is the oxidative stress theory, which is under debate in the scientific community and not yet fully conclusive.
