It's well known that ethyl alcohol kills bacteria. And amount of alcohol in urine may be detected by EtG tests (as long as 3-4 days after intake).

Does drinking alcohol in reasonable amount by healthy individual (non alcoholic) having UTI helps to kill bacteria in the urinary tract (in order to get rid of them quicker)?

    $\begingroup$ Nope, it does not. Alcohol is resorbed by the body and metablized. Additionally, to kill bacteria, you need 70% alcohol - which is a very bad idea to have this concentration in your body. $\endgroup$ – Chris Apr 26 '16 at 19:10

To begin answering your question,

Does drinking alcohol in reasonable amount by healthy individual (nonalcoholic) having UTI helps to kill bacteria in the urinary tract (in order to get rid of them quicker)?

We have to clarify that EtG detects ethyl glucuronide which is a byproduct of ethanol and remains in the urine for several day. The presence of ethyl alcohol in urine is significantly shorter somewhere between 8-12 hours (reference).

So what does this mean? Well, in order to "kill" the bacteria causing the UTI it must be exposed to a minimal inhibitory concentration of ethyl alcohol for a certain amount of time. Depending on the bacteria causing the infection this concentration and exposure time varies.

So if the concentration of ethyl alcohol was high enough and the flow of your urination and micturition long enough, maybe, but is unlikely to have much effect.

    $\begingroup$ Good answer, but I would get rid of the last paragraph. The concentration of ethanol in urine is never going to be high enough to kill even a small percentage of bacteria present. In the United States, a person is legally drunk if their blood alcohol content (BAC) is between 0.08% and 0.1%, depending on the state. Even assuming that unmetabolized alcohol is concentrated 10-fold, and a person is very drunk with a BAC of 0.3%, 3% EtOH won't kill much of anything, especially if it's in a biofilm, as UTIs are. $\endgroup$ – MattDMo Apr 26 '16 at 21:08
