What is non-gonococcal urethritis (ngu)?

Non-gonococcal urethritis (NGU) is inflammation of the urethra not caused by gonorrhea. It is frequently caused by chlamydia and other organisms, and is one of the most common reasons men seek STI care.

It causes urethral discomfort and discharge, and is diagnosed by testing that rules gonorrhea in or out and identifies the responsible organism. It responds well to the right antibiotic.

Causes

  • Chlamydia trachomatis (a common cause)
  • Mycoplasma and ureaplasma species
  • Other organisms causing urethral inflammation
  • Unprotected sexual contact

Symptoms

  • Clear or cloudy discharge from the penis
  • Burning or discomfort when urinating
  • Itching or irritation inside the urethra
  • Milder symptoms than typical gonorrhea
  • Sometimes minimal or no symptoms

Self-check: should you get this looked at?

  • You have urethral discharge or irritation
  • Urination is uncomfortable
  • Gonorrhea testing was negative but symptoms persist
  • A partner has chlamydia or NGU
  • You had unprotected sex recently

If several of these apply to you, a urological evaluation is worthwhile. This checklist is a guide, not a diagnosis.

Accurate diagnosis

How we diagnose it

Confidential consultation

A private review of symptoms and exposure guides testing.

Urethral & urine testing

Testing distinguishes NGU from gonorrhea and identifies the organism, including chlamydia.

Exclude gonorrhea

We confirm whether gonorrhea is present, since treatment differs.

Clear explanation

Results and the treatment plan are explained confidentially.

Treatment

How we treat non-gonococcal urethritis (ngu)

Targeted antibiotics

NGU is treated with antibiotics chosen for the likely or identified organism.

Treat the cause

Where chlamydia or another organism is confirmed, treatment is directed accordingly.

Partner advice

Partner testing and treatment prevent reinfection and complications.

Follow-up

We recheck where indicated to confirm resolution.

NGU is diagnosed by proper testing here rather than assumed, distinguishing it from gonorrhea so the right antibiotic is used. Care is confidential, led by a board-certified urologist, with English-speaking support.

Frequently asked

Questions from foreign patients

NGU is urethral inflammation not caused by gonorrhea — often by chlamydia. Testing tells them apart, which matters because the treatment differs.

It is very treatable, but untreated chlamydia (a common cause) can lead to complications, so testing and treatment are worthwhile.

Yes — partner testing and treatment prevent reinfection. We advise confidentially.

Reinfection is possible if a partner is untreated; completing treatment and partner care reduce this.
