Urinary tract infections are among the most common bacterial infections, affecting millions of Australians each year. They occur when bacteria — most commonly Escherichia coli — enter the urinary tract and multiply. Women are significantly more at risk than men due to anatomical differences, and sexual activity is one of the most common triggers. According to the Australian STI Management Guidelines, UTI symptoms overlap significantly with sexually transmitted infections, making concurrent testing essential for accurate diagnosis.
The classic symptoms of a UTI include burning or stinging when urinating, frequent urge to urinate, passing small amounts of urine, cloudy or strong-smelling urine, and pelvic pain or pressure. These symptoms are remarkably similar to those of chlamydia and gonorrhoea, which is why treating assumed UTIs without testing can mean missing an underlying STI. Studies have shown that a significant proportion of young women treated for UTI in emergency departments actually had undiagnosed chlamydia.
Testing for a UTI uses a midstream urine sample that is sent for culture and sensitivity testing. This identifies the specific bacteria causing the infection and determines which antibiotics will be most effective. At Clinic365, the $39 online test includes a urine culture for UTI alongside the standard five-infection STI screen using the same urine sample, so both conditions are investigated simultaneously in a single pathology visit.
There is no window period for UTI testing — symptoms typically appear within one to three days of infection. If you have symptoms of a UTI, testing should be done as soon as possible. Results from urine culture typically take two to three days as the bacteria need time to grow in the laboratory. Your Specialist GP may prescribe empirical antibiotics while awaiting results if symptoms are severe.
Standard UTI treatment is a short course of antibiotics, chosen based on the culture and sensitivity results. Most uncomplicated UTIs resolve within three to five days of treatment. Recurrent UTIs — defined as three or more episodes per year — are common and may require a different management approach including prophylactic antibiotics, post-coital antibiotics, or lifestyle modifications. Untreated UTIs can spread to the kidneys and cause a more serious infection called pyelonephritis, which may require hospital treatment.
Regular sexual health screening is recommended for anyone who is sexually active, even when no symptoms are present. Most sexually transmitted infections produce no noticeable symptoms in the early stages, which means they can be unknowingly passed to sexual partners. Australian guidelines recommend at least annual screening for sexually active adults, and more frequent testing for those with new or multiple partners. If you have had unprotected sex with a new partner, testing is recommended even if you feel well.
If your test results are positive, your Specialist GP will contact you directly to discuss treatment options and arrange treatment. Most bacterial STIs respond well to a short course of antibiotics and are straightforward to manage when detected early. Partner notification is an important part of treatment — all recent sexual partners should be informed and tested, even if they have no symptoms. Your GP can advise on how to approach this conversation, including anonymous notification options if preferred.
