From the Guidelines

Urea urethritis is not a recognized medical condition, and the term may represent a confusion between urea (a waste product excreted in urine) and urethritis (inflammation of the urethra). The relationship between urea and urethritis is non-existent, as urea is a waste product excreted in urine, while urethritis refers to inflammation of the urethra, typically caused by infections such as gonorrhea or chlamydia 1.

Causes and Treatment of Urethritis

Urethritis is usually caused by bacterial infections, and the treatment depends on the causative organism.

  • For gonococcal urethritis, the recommended treatment is ceftriaxone 1 g intramuscularly or intravenously as a single dose, often combined with azithromycin 1 g orally as a single dose 1.
  • For non-gonococcal urethritis, the first-line treatment is doxycycline 100 mg orally twice daily for 7 days, or azithromycin 500 mg orally on day 1, followed by 250 mg orally for 4 days 1.

Importance of Proper Diagnosis and Treatment

Proper diagnosis through testing is essential before initiating treatment, as symptoms alone are not sufficient to determine the cause of urethritis 1. Patients should abstain from sexual activity until treatment is complete, and partners should be treated simultaneously to prevent reinfection 1.

Symptoms and Prevention

Symptoms of urethritis include urethral discharge, burning during urination, and urinary frequency. The inflammation occurs when pathogens invade the urethral mucosa, triggering an immune response that causes the characteristic symptoms 1. Prevention of urethritis involves practicing safe sex, getting regular screenings for sexually transmitted infections, and seeking medical attention if symptoms persist or recur after treatment 1.
