How is prostatitis diagnosed?
If your doctor thinks that you have prostatitis or another prostate problem, he or she may refer you to a urologist (a doctor who specializes in diseases of the urinary tract and the male reproductive system) to confirm the diagnosis.
Patients usually have a full examination. The examination will include a digital rectal exam, in which the doctor inserts a gloved, lubricated finger into the rectum to feel the prostate.
At the first appointment, the patient should have a full bladder and should not be on any antibiotics. The patient will urinate into a machine to measure urine flow, and will also have an ultrasound of the bladder to see how it is emptying. Cultures are obtained from urine and from prostatic fluid obtained during a rectal exam.
