Acute prostatitis is swelling and irritation (inflammation or infection) of the prostate gland that develops rapidly.
Acute prostatitis is usually caused by a bacterial infection of the prostate gland. Any bacteria that can cause a urinary tract infection can cause acute bacterial prostatitis, including:
Some sexually transmitted diseases (STDs) can cause acute prostatitis, typically in men younger than age 35. These STDs include:
Prostatitis from an STD usually comes soon after sexual contact with an infected partner.
In men older than age 35, E. coli and other common bacteria typically cause prostatitis. E. coli prostatitis may occur spontaneously or after:
Acute prostatitis may also develop from problems involving the urethra or prostate, such as:
Prostatitis is rare in young boys. Men ages 20 - 35 who have multiple sexual partners are at an increased risk. Also at high risk are those who engage in anal intercourse, especially without using condoms.
Men age 50 or older who have an enlarged prostate (benign prostatic hyperplasia) are at increased risk for prostatitis due to their risk of urinary tract infection.
Prostatitis may occur with an infection in or around the testicles (epididymitis or orchitis), especially if it was caused by an STD. In this case, there will also be symptoms of the other condition.
Symptoms of acute prostatitis are more likely to start quickly and cause greater discomfort. They may include the following:
Other symptoms that may occur with this condition:
During a physical examination, your health care provider may find the following signs:
Examination of the discharge from the prostate may show increased white blood cells and bacteria.
Note: Your health care provider may choose not to perform a prostate massage if the prostate is obviously swollen and tender. Massage may spread the infection and cause bacteremia or sepsis. These are potentially life-threatening infections in which bacteria are in the bloodstream, rather than in just one part of the body.
Acute prostatitis may also affect the results of the following tests:
Most cases of acute prostatitis clear up completely with medication and slight changes to the diet and behavior.
Because it is possible for the infection to relapse, some health care providers recommend even longer courses of medication -- 6 to 8 weeks -- to get rid of the infection.
Stool softeners may reduce the discomfort that occurs with bowel movements.
Surgery, urinary catheterization, or cystoscopy are not recommended for patients with acute prostatitis.
After you finish antibiotic treatment, get examined by your health care provider to make sure the infection is gone.
Most men who are accurately diagnosed with acute prostatitis become symptom-free after treatment.
Patients who have had acute prostatitis may have the infection come back or develop chronic prostatitis.
Chronic prostatitis or prostatic abscess can develop. Urinary retention may occur as the swollen prostate presses on (compresses) the urethra.
Call your health care provider if you have symptoms of prostatitis.
Not all types of prostatitis are preventable.
You can prevent infections caused by STDs by practicing safer-sex behaviors.
