title: [Chronic bacterial prostatitis. Clinical and microbiological study of 332 cases].
abstract: OBJECTIVE
  Chronic bacterial prostatitis (CBP) is characterized by long-lasting symptoms, frequently associated with psychosomatic disorders. The objective of the study was to study PCB in our environment clinically and microbiologically.
  
  
  METHODS
  Between January 2013 and December 2014 761 patients with suspected CBP were studied. Of these patients 332 (43.6%) underwent a complete microbiological study and the major clinical signs and symptoms were collected.
  
  
  RESULTS
  Eighteen point four percent of patients were diagnosed microbiologically with CBP, Enterococcus faecalis being the main aetiologic agent (37.7%), followed by Escherichia coli (22.2%). Ninety-six point seven percent of the CBP had positive semen cultures, while only 22.9% had positive urine post-semen cultures. Data of sensitivity, specificity, positive predictive value and negative predictive value of semen were 96.7%, 95.9%, 84.3% and 99.3%, respectively and urine post-semen 22.9%, 99.3%, 87.5% and 85.1%, respectively. Testicular perineum pain (44.3%), ejaculatory discomfort (27.9%) and haemospermia (26.2%) were highlighted as the patients' main clinical manifestations.
  
  
  CONCLUSIONS
  Fractionated culture for the microbiological diagnosis of CBP could be simplified by the culture of urine pre-semen and semen, without the need for the culture of urine post-semen. The main aetiologic agent of CBP in our media was Enterococcus faecalis, followed by Escherichia coli.
