Chronic prostatitis - Le, Brian; Schaeffer, Anthony J
Chronic prostatitis can cause pain and urinary symptoms, and usually occurs without positive bacterial cultures from prostatic secretions (known as chronic abacterial prostatitis or chronic pelvic pain syndrome [CP/CPPS]).
Bacterial infection can result from urinary tract instrumentation, but the cause and natural history of CP/CPPS are unknown.
