Causes

Acute bacterial prostatitis is often caused by common strains of bacteria. The infection can start when bacteria in urine leak into your prostate. Antibiotics are used to treat the infection. If they don't eliminate the bacteria prostatitis might recur or be difficult to treat (chronic bacterial prostatitis).

Nerve damage in the lower urinary tract, which can be caused by surgery or trauma to the area, might contribute to prostatitis not caused by a bacterial infection. In many cases of prostatitis, the cause isn't identified.
