Etiology of Prostatitis
Prostatitis can be bacterial or, more commonly, nonbacterial. However, differentiating bacterial and nonbacterial causes can be difficult, particularly in chronic prostatitis. Bacterial prostatitiscan be acute or chronic and is usually caused by typical urinary pathogens (eg,Klebsiella,Proteus,Escherichia coli) and possibly byChlamydia. How these pathogens enter and infect the prostate is unknown. Chronic infections may be caused by sequestered bacteria that antibiotics have not eradicated. can be inflammatory or noninflammatory. The mechanism is unknown but may involve incomplete relaxation of the urinary sphincter and dyssynergic voiding. The resultant elevated urinary pressure may cause urine reflux into the prostate (triggering an inflammatory response) or increased pelvic autonomic activity leading to Chronic Pain without inflammation.
