Why Does Your UTI Keep Coming Back After Antibiotics? | Ruth Kriz Part 1

A negative culture is supposed to mean the infection has gone. Ruth Kriz is a nurse practitioner who spent 35 years on chronic UTI and interstitial cystitis. She says that in a chronic case a clean result often means the test could not reach it. The bacteria may be embedded in biofilm in the bladder wall. A culture may not find them. Antibiotics may not reach them. I asked her what accurate testing looks like instead and why she treats these infections in layers. If you have been told your results are clean while you still feel ill, start here. Key Insights: ✅ Chronic Infection May Hide in Biofilm ✅ Culture Media Favors Fast Growing E.
