NGU question

If a person had NGU would a  urinalysis show that there is an infection?



I have been having a clearing morning discharge and urge to urinate that doesnt go away even after urinating. I had a urinalysis done friday and was told there was no sign of infection but I was wonding if NGU would show in that test. I know that they would not be able to tell what specific bacteria was present but would it make the test positive?

A routine urinalysis usually will be normal in NGU.  The exception is if you provided just the first 15-30 ml of urine (1-2 tbsp), as a urethral "washout".  Even then, the standard urinalysis tests often will miss anything abnormal.

Do you think my symptoms sound like NGU?

Urge to urinate not changed by urinating

Yes, those symptoms could be due to NGU, but of course that would be unlikely if your sexual lifestyle doesn't put you at risk.  If in doubt, see a health care provider who is familiar with STDs.

My question had to do with risks.



How much of a risk is there for NGU infection through unprotected oral sex?



The last unprotected vaginal sex I had besides my wife was a year and a half ago. Would over a year be too long for symptoms of NGU to show up?



I know you cant judge my wifes possibilty of parnters but lets just assume there are no others.



Both my wife an I were tested for Chlamydia and Gonorrhea and both were negitive. My test was after I had been off of antibiotics for about 10 days from an unrelated issue.



Thanks again doc for your help

There isn't a lot of research on NGU acquisition by fellatio, but most STD experts believe it occurs.  A review of medical records in an STD clinic showed that 40% of NGU in gay men occurred in men whose urethras had been orally but not anally exposed in the preceding 2 months.  The best guess is that bacteria that are normal in the mouth cause inflammation in the urethra.  This may explain some cases of NGU in men in mutually monogamous relationships.  However, there are no data at all on the risk of this happening, i.e. the percent chance of getting NGU for each oral exposure.  But it must be quite low; although NGU is a common problem, it is very much less common than the frequency of fellatio in the population.



As to your other question, a year and a half probably is too long to attribute current NGU.



Finally, nonchlamydial NGU remains a mystery in lots of ways.  For example, it is likely that some cases aren't infectious at all, and perhaps not related to sex at all; I suspect some cases are due to an unexplained, non-infectious inflammatory response, perhaps due to an immune system anomaly.  Happily, nonchlamydial NGU appears to be benign, without any serious health outcomes for either men or their partners.  But the downside of the benign nature is that there hasn't been much incentive for research.
