text: <unk>  is an inflammation of the prostate gland.<unk>  has been classified by International<unk>  Collaboration Network, into 5 subtypes. This classification is on the basis of timing of the symptoms and the presence of bacterial pathogens and other markers of infection and inflammation. The categories include acute bacterial<unk> , chronic bacterial<unk> , inflammatory chronic<unk> /chronic pelvic pain syndrome, non-inflammatory chronic<unk> /chronic pelvic pain syndrome, and asymptomatic inflammatory<unk> . By the help of microscopic histopathological studies, neutrophils or lymphocytes can be seen inside the glands, between the cells of epithelium or inside the stromal component. The most common bacteria causing<unk>  are aerobic gram-negative bacilli, Escherichia coli is responsible for 50-80% incidents of bacterial<unk> . Though a single definitive cause has not been established, different theories exist about chronic<unk> /chronic pelvic pain syndrome pathogenesis including chemical damage owing to reflux or autoimmune process.<unk>  must be differentiated from various causes of dysuria including pyelonephritis, cystitis, urethritis, benign prostatic hyperplasia, prostatic abscess, bladder cancer, urinary tract stones, and a foreign body within the urinary tract. Recurrent urinary tract infections, benign prostatic hyperplasia, urethral strictures, bladder neck hypertrophy, prostatic carcinoma, and catheterization are risk factors for<unk> . Acute<unk>  usually results in complete recovery without sequelae. If left untreated, patients with acute bacterial<unk>  may progress to develop chronic<unk> , epididymitis, prostatic abscess, septicemia, urosepsis, urinary retention and metastasis of infection to spinal cord or sacroiliac joint. Patients with untreated chronic<unk>  may develop chronic pelvic pain, sexual dysfunction, infertility and recurrent urinary tract infections. Frequency, urgency, burning during urination, nocturia, urinary retention and pain in the genital area, groin, lower abdomen, or lower back may be the presenting features. Other features include fever, nausea, and vomiting in acute infection. Laboratory findings show an increase in the number of leukocytes on CBC, bacteria on urine culture, elevated C-reactive protein, and transiently elevated PSA (prostate specific antigen) levels in case of bacterial<unk> . While in chronic bacterial<unk>  negative pre-massage urine culture results, more than 10 to 20 leukocytes per high-power field in both the pre and the post massage urine specimen, bacteriuria in the postmassage urine specimen, and lower leukocyte and bacterial counts in voided bladder urine specimens as compared to bacterial count in post-prostatic massage voided urine or expressed prostatic secretions are seen. The absence of bacterial growth on cultures is diagnostic of chronic nonbacterial<unk> .
  Antimicrobial therapy is indicated for acute and chronic<unk> .
