NSU
Non-specific urethritis (NSU) is inflammation of the urethra. Both men and women can have NSU but it is more difficult to diagnose in women. This information looks at NSU in men, not women.
Symptoms
Not all men who have inflammation will show any signs or symptoms, or they may be so mild they are not noticed.
If you do get signs and symptoms you might notice:
• White or cloudy discharge from the penis, usually more noticeable first thing in the morning.
• Pain or a burning sensation when passing urine.
• Feeling that you need to pass urine frequently.
• Itching or irritation at the end of the urethra.
NSU can be caused by other STIs such as chlamydia, trichomonas vaginalis and genital herpes.
Treatment
Tests are free on the NHS. Testing can be done at your GPs, a GUM or sexual health clinic.
The tests may involve:
• Using a swab to collect a sample of cells from the entrance of the urethra.
• A urine sample.
• Examining your penis

NSU is treated with antibiotics. There are several different antibiotics that can be used, either as a single dose or a longer course (up to two weeks). It is important that past and current sexual partners are also treated to prevent any infection spreading to other people.
