What is Non-Specific Urethritis

Non-specific urethritis or non-gonococcal urethritis (also known as NSU, or NGU) is inflammation of the urethra that is caused by an infection. NSU only affects people with a penis, and is not an STI, although it can be caused by some STIs. 

How is transmitted?

NSU cannot be passed on from partner to partner, however, the STIs that cause it can be. It can be caught from vaginal, anal or oral sex, or other infections that affect the urethra. Rarely, it can be caused by damage to the urethra following a catheter. 

Symptoms of NSU

NSU symptoms include: 

  • Discharge from the penis that can be white or cloudy 
  • Pain, burning or stinging when you urinate (wee) 
  • Irritation or soreness around the head or tip of the penis 

If NSU is caused by an STI, you may not always develop symptoms right away, some NSU infections do not come with any symptoms (asymptomatic). Delayed symptoms may appear days, or even weeks after infection. 

Prevention and protection  

Condoms: using condoms during sex can prevent passing on STIs and unplanned pregnancy. Covering sex toys with a new condom after each use is recommended.  

Regular testing: testing after every new sexual partner, or at least twice a year is important to avoid passing on STIs 

Conversations: having open and honest conversations with your sexual partner(s) around STIs and protection is essential 

Damage: avoid using irritating products on the genitals, inserting objects into the urethra (including sounding), or vigorous sex/masturbation as these may cause damage to the urethra 

Treatment for NSU

Treatment is usually a short course of antibiotics. It is important to take your treatment correctly and complete it to avoid reinfection. Your sexual partner(s) will need to be treated at the same time, and you will need to avoid sexual intercourse until you all have finished treatment.  

You may be invited to a follow-up appointment within 1-2 weeks to make sure the treatment has worked; however, this is not common. 

Where to get help in Bexley

If you are showing symptoms and want to get tested, you can visit your local sexual health clinic or GP in the London Borough of Bexley. They can provide confidential testing and treatment.  

For more information, visit the NHS website or contact your local healthcare provider. 

What happens at your appointment?

A doctor or nurse will ask about your symptoms and your recent sexual partners. A swab sample will be taken from your urethra - this may feel uncomfortable for a few seconds. You will also need to give a urine sample and will be offered a test for STIs. If NSU is detected, you will be prescribed treatment. 

Complications of NSU

Complications are rare, however sometimes NSU can cause further problems such as:  

  • Epididymitis (infection of the testicles) 
  • Reactive arthritis – the immune system attacks the joins and/or eyes which can lead to joint pain or conjunctivitis.
