prostatism

++

(prŏs′tă-tĭzm) [″ + -ismos, condition] Any condition of the prostate gland that interferes with the flow of urine from the bladder. The condition is characterized by frequent uncomfortable urination and nocturia. Retention of urine may occur with development of uremia. Causes include benign hypertrophy, carcinoma, prostatitis, and nodular hyperplasia.

++

prostatitis

++

(pros″tă-tīt′ĭs) [prostate + -itis] Inflammation of the prostate gland, usually as a result of infection.

++

acute bacterial p. Prostatis commonly associated with urinary tract infections caused by enterococci, staphylococci, or gram-negative bacteria such as Escherichia coli. It often is caused by reflux of urine resulting from an anatomical abnormality. Patients present with fever, chills, urethral discharge, pain on urination, difficulty voiding, malaise, myalgias, and discomfort in the perineal area; the prostate is soft, swollen, and tender on examination.

++

 The causative organism is identified through a culture of prostatic secretions and is treated with an extended course of antibiotics. Narcotics and antispasmodics may be needed to relieve pain.

++

chronic abacterial p. Prostatis marked by dull, aching pain in the perineum, usually of long duration. This is the most common type of chronic prostatitis, and its cause is unknown.

++

chronic bacterial p. ABBR: CBP. Prostatis caused by a long-standing bacterial infection that often develops insidiously. Causative organisms include gram-negative bacteria and enterococci. Clinically, the patient may have mild to moderate low back pain, pain with urination, and perineal discomfort, or he may be asymptomatic. Patients may have a history of multiple urinary tract infections; bacteria can hide in the prostate, which resists penetration by antibiotics, and reinfect the urinary tract. Causal bacteria are identified by culture of prostatic secretions and urine. Treatment consists of ciprofloxacin or another fluoroquinolone antibiotic for 4 to 6 weeks. The long course is needed because of poor penetration into the prostate.

prostato-, prostat-

++

[Gr. prostates (adēn), prostate (gland), fr. pro- + -stat] Prefixes meaning prostate gland.

++

prostatodynia

++

(prŏs″tă-tō-dĭn′ē-ă) [″ + odyne, pain] The condition of having the symptoms and signs of prostatitis but no evidence of inflammation of the prostate, with negative urine culture. Use of antibiotics in patients with prostatodynia is unnecessary. SEE: proctalgia fugax.
