Definition of Urethritis:
Urethritis is inflammation of the urethra from any cause.
Causes, incidence, and risk factors:
Urethritis may be caused by bacteria or a virus. The same bacteria that cause urinary tract infections (E. coli) and some sexually transmitted diseases (chlamydia, gonorrhea) can lead to urethritis. Viral causes of urethritis include herpes simplex virus and cytomegalovirus.
Other causes include:
- Sensitivity to the chemicals used in spermicides or contraceptive jellies, creams, or foams
- Injury
Risks for urethritis include:
- High-risk sexual behavior (such as anal sex without a condom)
- History of sexually transmitted diseases
- Male, ages 20 - 35
- Many sexual partners
- Young women in their reproductive years
