Non Specific Urethritis (NSU)


What is it?


Non-specific urethritis (NSU) is where the urethra (the tube that you pee through) is inflamed (swollen) and sore.

NSU can be caused by a bacterial infection that is passed on by sexual contact such as sex without a condom, or damage to the urethra.


What are the symptoms or signs?


When the NSU is caused by an infection, the common symptoms are:


Symptoms can take between one and three weeks to appear.




NSU is diagnosed by a genital examination by a doctor or nurse together with a urine sample or a urethral swab.


Can it be treated?


NSU is treated with a course of antibiotics. Once you have finished the treatment you may need to be tested again to check if that the infection has been completely treated. If left untreated NSU can lead to pelvic inflammatory disease and infertility.


How can it be prevented?


Using condoms and water-based lube can reduce the risk of passion on or getting the infections that cause NSU.
