INTRODUCTION TO CHRONIC PROSTATITIS AND CHRONIC PELVIC PAIN SYNDROME (CP/CPPS)

Abstract

Prostatitis is the most frequently diagnosed illness in men under 50, accounting for about 8% of all consultations with urologists. Estimates based on published studies suggest that the incidence of prostatitis in the population is somewhere between 4% and 11%. In 1995 the National Institutes of Health (NIH) classified prostatitis into 4 main categories: 1) acute bacterial; 2) chronic bacterial; 3) pelvic pain syndrome; 4) asymptomatic inflammatory. The aetiological agent most often involved is bacterial, particularly the category of Gram (-) bacteria, followed by Gram (+), chlamydiae and mycoplasms; however many cases of prostatitis are caused by bacteria which are difficult to isolate or by aetiopathogenic mechanisms which are immunological, neurological, psychosomatic or anatomical in nature. An observational study was recently done on the Italian territory in order to estimate the incidence and risk factors of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). The disease incidence estimation was 13.8%. cigarette smoking, high caloric diet with low consumption of fruit and vegetables, constipation, meteorism, slow digestion, sexual relationship with more than one partner and coitus interruptus were more likely in CP/CPPS patients than in controls (p<0.001). CP/CPPS had a negative influence on sexual desire, erectile dysfunction and premature ejaculation (p<0.001). the Meares Stamey test was positive in 13.3% of patients and 2.9% of controls.
