Urethritis is inflammation of the urethra from any cause.

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.

People who are sensitive to the chemicals used in spermicides or contraceptive jellies, creams, or foams may develop urethritis.

Injury 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 anal sex without a condom) have the highest risk for urethritis. Young women in their reproductive years are also at risk. A prior history of sexually transmitted diseases raises one's risk of urethritis.

In men:

• Burning pain while urinating (dysuria)
• Increased urinary frequency or urgency
• Itching, tenderness, or swelling in penis or groin area
• Fever (rare)
• Discharge from penis (usually moderate, yellow or clear, possibly purulent)
• Pain with intercourse or ejaculation
• Blood in the urine or semen

In women:

• Burning pain while urinating
• Increased urinary frequency or urgency
• Fever and chills
• Nausea and vomiting
• Abdominal pain
• Vaginal discharge
• PID (pelvic inflammatory disease)
• Other infections of reproductive organs (cervicitis, salpingitis)
• Fertility problems
• Pelvic pain
• Ectopic pregnancy
• Complications of pregnancy (miscarriage, preterm delivery, premature rupture of membranes, fetal infection, postpartum infection)

The health care provider will perform a physical examination. For men, the areas to be examined include the abdomen, bladder area, penis, and scrotum. A digital rectal exam will also be performed. The physical exam may reveal tender and enlarged lymph nodes in the groin area, discharge from the penis, or a tender and swollen penis.

For women, areas to be examined include the abdominal and pelvic exams. The health care provider will check for lower abdominal tenderness, uterine tenderness, and discharge from the urethra.

The following laboratory tests may be done:

• Urinalysis and urine cultures
• Tests for gonorrhea and chlamydia and other sexually-transmitted diseases
• Pregnancy test (women only)
• CBC (complete blood count)
• C-reactive protein test
• Pelvic ultrasound (women only)
