UTI Myths

– UNDER CONSTRUCTION –

 

UTI Myth 1: Urinary dipsticks and MSU cultures are a reliable way to diagnose a UTI

FALSE

Urinary dipsticks used by doctors as a first-line diagnostic tool have been widely discredited with research showing they miss up to 70% of infections.1, 2, 3  Research also shows that the fundamentally flawed MSU culture test misses 50–80% of UTIs 3, 4

If you feel as though you have a UTI but your tests come back negative, talk to your doctor about the proven inadequacies of gold standard UTI tests.  Ask your doctor to read this 2019 research paper before dismissing your symptoms, ‘Reassessment of routine midstream culture in diagnosis of urinary tract infection’.

UTI Myth 2: A 3-5 day course of antibiotics is adequate to treat a UTI, even if you have lingering UTI symtpoms after your treatment is complete

False

An estimated 25-35 percent of people treated according to current clinical guidelines for UTI fail to respond to treatment.1, 2   If you have finished your course of treatment and you feel your infection has not fully gone, and you still have white blood cells showing in your urine sample, there is a good chance you are right.  Go back to your doctor and talk to them about the known failure rate of UTI treatment.

UTI Myth 3: Recurrent UTIs are new infections caused by introducing new bacteria into the bladder through acts like poor personal hygiene (ie wiping back to front), sexual intercourse, not drinking enough water, tight clothing, underwear made form synthetic fabrics etc.

False

There is no clinical evidence supporting the long-held belief that recurrent UTIs are caused by the introduction of new bacteria due to poor personal hygiene, sexual intercourse, inadequate fluids, tight clothing or wearing synthetic underwear.  However, researchers have shown that bacteria (such as E. coli) can invade the cells that line the bladder very early on in an acute UTI, forming biofilm-like intracellular bacterial communities.  The bacteria are able to communicate between themselves via a process known as ‘quorum sensing’ and act as a bacterial reservoir capable of seeding future acute attacks and/or ongoing lower urinary tract symptoms. 1

If you are sick and tired of being told you are responsible for your recurrent UTIs, tell your doctor what you have learned about bacteria becoming embedded in the bladder lining where they go on to cause recurrent acute UTI attacks or ongoing UTI symptoms.  Direct your doctor to this Chronic UTI picture commentary by Emeritus Professor James Malone-Lee.
