Non-specific urethritis (NSU) has a very broad meaning. It used to apply to any urethritis, which is not gonococcal in origin (also referred to as non-gonococcal urethritis [NGU]). However, since chlamydia can now be diagnosed specifically, NSU, in these guidelines, refers to causes of urethritis where gonorrhoea and chlamydia have been excluded, and where there are > 5 WBC/HPF on microscopy.
It is assumed that the patient presenting with a discharge has already had treatment for gonorrhoea and/or chlamydia as per the management of discharge. If the patient is no longer symptomatic following treatment no further treatment is required at follow-up.
For the management of men with a discharge at first presentation, see Urethral discharge dysuria.
It is important that the partner is also tested and treated.
