Answer

Most cases of chronic bacterial prostatitis (CBP) can be diagnosed with history, physical examination, and urine or semen culture.  A urine dipstick is often done as the same time as urine culture collection to evaluate for signs of infection and hematuria. 

The formal diagnosis of CBP includes a history of  recurrent urinary tract infections (UTIs) and a 10-fold increase in bacteria in expressed prostatic secretion (EPS), post-massage urine, or semen culture. [30]  As discussed below, the "four-glass test" to collect EPS is the gold standard for diagnosis, but this test is cumbersome and not widely used in the clinical setting; often a urine or semen culture is adequate for diagnosis.
