I have not heard that, but after joint replacements, antibiotics are to be taken before all dental procedures, even just cleanings. It seems that it could be feasible.

@angels12 Hard to say! Overall, your risk of infection after joint replacement is about 2%, mainly in the first 12 months. If you have certain other issues, your risk could be a little higher. See this article:

But, I can't find anything that directly addresses the risk from a UTI. I had always heard that an infection that has ready access to your bloodstream (like infectious tissue during a dental procedure) were more risky. Since a UTI is contained, that may mean a lower risk (unless you have a persistent low-grade infection that keeps flaring. I had a 2 persistent lung infections for over 24 months, and neither affected my joint implants. And last year I had a persistent staph infection for over 3 months on my leg and arm - they did not make it to my hips either.
For a better answer, you might want to consult with an infectious disease doc.
