If you’ve ever been told your urine test came back negative but you know something is wrong, this episode is for you.

Host Melissa Kramer speaks with Professor Jenny Roan, Head of the Centre for Urological Biology at University College London (UCL), to get into the science that most people living with recurrent or chronic UTI desperately want to understand. From why the dipstick test misses so many real infections, to what’s actually happening inside the bladder wall when antibiotics stop working, Professor Roan breaks it all down in plain language, without dismissal.

Professor Roan also shares details of a novel treatment her team at UCL has developed, CapFuran, a microencapsulated nitrofurantoin designed to deliver the antibiotic directly into the bladder wall to target embedded bacteria and biofilms that standard antibiotics simply can’t reach. With a potential clinical trial horizon of 2026–2027, this is the research the chronic UTI community has been waiting for.


3 Key Takeaways

  1. Your negative test result doesn’t necessarily mean there’s no infection. Dilution, the wrong type of bacteria, mixed growth being discarded… There are multiple scientific reasons a real UTI can be missed. The research highlighting these inadequacies has existed for decades.
  2. Chronic UTI may involve bacteria that are literally hiding inside your bladder wall. These intracellular bacteria and biofilms are dormant and largely unreachable by standard short-course antibiotics, which is why a three-day course of nitrofurantoin often isn’t enough.
  3. Research into new treatments is moving forward and the patient community is part of the push. From the uro-immune vaccine to a novel encapsulated antibiotic therapy targeting embedded infection, there are promising options in development. The more patients ask questions and advocate for themselves, the harder it becomes to ignore this area of health.
