DefinitionUrethritis is an inflammation (irritation with presence of extra immune cells) of the urethra.
Causes, incidence, and risk factors
Urethritis may be caused by the same organisms that cause urinary tract infections (for example, E. coli or klebsiella) and by some sexually transmitted diseases (for example, chlamydia , gonorrhea , and Ureaplasma urealyticum infections). Viral causes of urethritis include herpes simplex virus and cytomegalovirus. Urethritis may also develop because of a chemical irritation (such as spermacide in condoms or contraceptive jelly, cream, or foam). Trauma may also cause urethritis.
Men between the ages of 20 and 35, those with multiple sexual partners, and those who engage in high-risk sexual behavior (such as lack of condom use, particularly during active anal intercourse) are at higher risk.
Young women in their reproductive years are also at risk. In women, common bacterial causes include gonorrhea, chlamydia, mycoplasma hominis , ureaplasma urealyticum , and mycoplasma genitalum . Risk factors include age younger than 20, unmarried status, inner-city population, multiple partners, and a prior history of STDs (sexually transmitted diseases).
Signs and tests
A thorough physical examination of genitourinary tract needs to be performed.
For men, this includes abdomen, flank, suprapubic (bladder) area, penile, scrotal and digital rectal exams. These exams may reveal tender and enlarged inguinal lymph nodes (groin area), discharge from the penis , and/or a tender and swollen penis.
For women, evaluation includes thorough abdominal and pelvic exams, evaluating for lower abdominal tenderness, uterine and adnexal tenderness, and purulent discharge from the urethra or cervix. Microscopic examination of the discharge may also aid in the diagnosis.
Laboratory tests include:
The goal of therapy is to improve symptoms, prevent spread of infection to other genitourinary tract organs/complications, and eliminate the cause of infection. Antibiotic therapy should be tailored to specific organism causing the infection; the patient may or may not need intravenous antibiotics.
Abstinence from intercourse or use of condoms should be recommended throughout the course of treatment. Again, partners must be treated as well.
With appropriate diagnosis and treatment, urethritis usually clears up without any complications. However, urethritis can lead to permanent damage to the urethra and other genitourinary organs in both men and women.
Urethritis may lead to cystitis ( bladder infection ), pyelonephritis ( kidney infection ), epididymitis (epididymis infection), orchitis (testes infection), or prostatitis (prostate infection) in men.
In women, urethritis may cause PID (pelvic inflammatory disease), cervicitis (infection of the cervix), salpingitis (infection of the ovaries), and fertility problems, as well as ectopic pregnancy, miscarriage, and other complications of pregnancy.
Calling your health care provider
Call your health care provider if symptoms suggesting urethritis occur, particularly if you have recently engaged in high-risk sexual behavior.
Some causes of urethritis may be avoided with good personal hygiene and by practicing safer sexual behaviors (such as monogamy and the use of condoms).
