Acute bacterial prostatitis typically presents as an acute onset of fever, chills, malaise, dysuria, and perineal or rectal pain. One study cited that over 96% of patients present with a triad of pain, prostate enlargement, and failure to void and 92% present with fever. [12] It may also present as dysuria, urinary frequency, urinary urgency, and, occasionally, urinary retention. Acute bacterial prostatitis can be a complication of previous instrumentation, such as cystoscopy or prostate needle biopsy. Hematuria, although rare, can be in the presentation.


Physical Examination

In most cases, perineal tenderness alone is sufficient for a diagnosis. If a digital rectal examination is performed, it must be done cautiously, as palpation can be very painful. Measurement of vital signs is necessary, to exclude signs and symptoms of sepsis. Urinary retention is occasionally seen; these patients present with an inability to void and abdominal fullness.
