A urinary tract infection (UTI) is an infection anywhere in the urinary system — most commonly the bladder, which is called cystitis. UTIs happen when bacteria, usually from the bowel, get into the urethra and travel up into the bladder. They’re extremely common, particularly in women, and while they’re usually simple to treat, they can be painful and disruptive.
Most UTIs are straightforward and clear quickly with the right treatment. What matters is making sure it actually is a UTI — because several sexually transmitted infections cause almost identical symptoms, and treating the wrong thing means the real infection goes untreated.
UTI symptoms
The classic symptoms of a bladder infection are hard to miss:
Burning, stinging or pain when you pee
Needing to pee urgently, or far more often than usual
Passing only small amounts each time
Cloudy, strong-smelling or discoloured urine
Blood in the urine
Lower abdominal or pelvic discomfort
These symptoms are uncomfortable but not usually dangerous. The important thing is what’s causing them — and that’s where testing comes in.
UTI or STI? The Symptoms Overlap Almost Exactly
This is the single most useful thing to understand about UTI symptoms: burning when you pee is one of the most common symptoms of chlamydia and gonorrhoea, too. Both infections can cause urethritis — inflammation of the urethra — which feels very much like a bladder infection. Trichomoniasis and herpes can also cause pain on passing urine.
The result is that people frequently assume they have a UTI, treat it as one, and never discover the actual cause. Meanwhile the STI stays untreated, can be passed to partners, and in some cases leads to complications like pelvic inflammatory disease or infertility.

You cannot reliably tell a UTI from an STI by symptoms alone — not as a patient, and often not as a clinician without testing. That’s exactly why testing for both at once is the sensible approach when there’s any chance of an STI.
Why get STI testing alongside UTI testing?
If you’re sexually active and you have urinary symptoms, testing for both a UTI and STIs at the same time is simply better medicine:
The symptoms don’t distinguish them. Burning and urgency point equally to either.
Treating the wrong one delays the right treatment. A UTI course won’t reliably clear chlamydia or gonorrhoea.
STIs are often silent. You may have both a UTI and an STI without any separate STI symptoms.
Untreated STIs have consequences. Pelvic inflammatory disease, infertility, and onward transmission to partners.
It costs you nothing extra in time. The same urine sample can usually be used for both.
Testing for UTI and STIs
UTI testing is quick and simple. It usually involves one or both of the following:
Urine dipstick. A rapid test strip that looks for signs of infection, giving a result in minutes.
Urine culture (MSU). A mid-stream urine sample sent to the lab, which identifies the exact bacteria and shows which treatments will work against it. This takes a couple of days but is far more informative — particularly for recurrent or stubborn infections.
STI testing uses the same kind of sample. Chlamydia and gonorrhoea are detected from a first-catch urine sample (the first part of your stream, rather than mid-stream) or from a swab, and blood tests cover syphilis and HIV. Everything can usually be collected in one go.
How testing works with Clinic365
A Specialist GP assesses your symptoms over a quick phone call and sends your pathology referral by SMS, covering both the urine test and STI testing where appropriate. You walk into any pathology lab Australia-wide — no appointment needed — and results come back by SMS, usually in 2-3 days. If treatment is needed, the Specialist GP arranges it, treating a UTI and any STI separately and specifically. You can screen broadly at the same time with the full STI test.
UTI Treatment, Recurrent UTIs and Men
Most uncomplicated UTIs are treated with a short course of antibiotics, and symptoms usually start improving within a day or two. Which antibiotic is appropriate depends on local resistance patterns, your medical history, whether you’re pregnant, and — where a culture has been done — exactly which bacteria are involved. Alongside treatment, drinking plenty of water and using simple pain relief can help while the antibiotics take effect. Complete the full course even once you feel better. If your tests also show an STI, that’s treated separately and specifically — a UTI course does not reliably treat chlamydia or gonorrhoea, which is precisely why testing for both matters.
Recurrent UTIs
Recurrent UTIs are usually defined as two or more infections in six months, or three or more in a year. They’re common and there are effective strategies to reduce them, including behavioural measures, treatment taken after sex, and in some cases longer-term preventive approaches. But there’s an important caveat: if you keep getting “UTIs” that never fully clear, keep coming back, or don’t respond to treatment, an untested STI is one of the classic explanations. Recurrent urinary symptoms in a sexually active person should always prompt STI testing — ideally before another round of antibiotics.
When treatment isn’t working
If your symptoms haven’t improved within a few days of starting treatment, don’t just wait it out. It may not be a UTI at all (chlamydia, gonorrhoea, trichomoniasis or herpes may be the real cause), the bacteria may be resistant to the antibiotic chosen (a urine culture identifies which one will work), the infection may have spread to the kidneys (which needs prompt, different treatment), or another cause entirely such as bladder irritation or thrush may be mimicking a UTI. The right next step is a review, a urine culture, and STI testing if that hasn’t been done — not repeated courses of antibiotics without testing.
UTIs in men
UTIs are much less common in men, and that matters. When a man has burning when passing urine, urethritis caused by an STI — chlamydia, gonorrhoea or mycoplasma genitalium — is a more likely explanation than a simple bladder infection, particularly in younger, sexually active men. A UTI in a man is also always considered complicated and warrants proper assessment rather than a quick course of antibiotics. If you’re a man with urinary symptoms, STI testing should generally be part of the workup from the start.
When to Seek Urgent Care, and Preventing UTIs
Seek medical care promptly if you have fever, chills or shaking, pain in your back or side (flank pain), nausea or vomiting, or feel very unwell or confused. These can indicate a kidney infection, which needs prompt treatment. Urinary symptoms in pregnancy also need same-day assessment, as do symptoms in anyone with diabetes, a weakened immune system, or a urinary catheter.
Reducing your risk of UTIs
Simple measures can lower your chance of getting a UTI: drink enough fluid, don’t hold on when you need to pee, pee soon after sex, and wipe front to back. These help, but they’re not a substitute for testing when you do have symptoms — and they won’t prevent an STI. Condoms reduce the risk of the sexually transmitted infections that mimic a UTI, and regular STI screening catches the ones that cause no symptoms at all.
Frequently asked questions
You often can’t tell from symptoms alone. Burning when you pee is a classic UTI symptom, but it’s also one of the most common symptoms of chlamydia and gonorrhoea, which cause urethritis. Trichomoniasis and herpes can do the same. If you’re sexually active and have urinary symptoms, testing for both is the only reliable way to know.
Very commonly, yes. People assume burning and urgency mean a bladder infection, take a course of antibiotics for it, and never discover they had chlamydia or gonorrhoea. The STI then goes untreated, can be passed to partners, and may lead to complications. This is one of the most frequent avoidable errors in urinary symptoms.
If you’re sexually active, yes. The symptoms overlap almost exactly, STIs often cause no other symptoms, and treating a UTI won’t clear chlamydia or gonorrhoea. Testing for both usually takes the same visit and often the same urine sample, so there’s very little downside and a lot to gain.
Usually with a urine dipstick, which gives a quick result, and often a urine culture (a mid-stream sample sent to the lab). The culture identifies the exact bacteria and which treatment will work — particularly valuable for recurrent or stubborn infections. STI testing uses a first-catch urine sample or a swab, and can be collected at the same time.
Most uncomplicated UTIs are treated with a short course of antibiotics, with symptoms usually improving within a day or two. The right antibiotic depends on your history, local resistance patterns, pregnancy, and any culture results. Drinking fluids and simple pain relief help meanwhile. Complete the full course even once you feel better.
Recurrent UTIs are common and there are effective preventive strategies. But if infections never fully clear or keep returning, an untested STI is a classic explanation — chlamydia or gonorrhoea can produce persistent urinary symptoms that antibiotics for a UTI won’t fix. Recurrent symptoms in a sexually active person warrant STI testing before another antibiotic course.
Don’t just repeat it. Possible reasons include: it isn’t a UTI (an STI may be the real cause), the bacteria are resistant to the antibiotic used, the infection has spread to the kidneys, or something else is mimicking a UTI. The right step is a review, a urine culture, and STI testing if it hasn’t been done.
Yes, but they’re much less common. In a younger, sexually active man, burning when passing urine is more likely to be urethritis from an STI such as chlamydia, gonorrhoea or mycoplasma genitalium than a simple bladder infection. A UTI in a man is always considered complicated, so STI testing and proper assessment should be part of the workup.
Yes, and it happens. Having one doesn’t rule out the other, and because STIs often cause no separate symptoms, a confirmed UTI doesn’t mean an STI isn’t also present. This is another reason testing for both at once is worthwhile if you’re sexually active and have urinary symptoms.
Seek care promptly if you have fever, chills, back or side pain, nausea or vomiting, or feel very unwell — these can indicate a kidney infection needing prompt treatment. Urinary symptoms in pregnancy need same-day assessment, as do symptoms in anyone with diabetes, a weakened immune system, or a urinary catheter.
Often, yes. A clinician can assess your symptoms by phone or video, arrange a urine test and STI testing through a pathology referral, and organise treatment. Some situations — severe symptoms, suspected kidney infection, pregnancy, or symptoms in men — may need in-person assessment. A clinician will tell you which applies.
For a simple UTI, sex isn’t prohibited, though many people prefer to wait until symptoms settle. If an STI is found or suspected, that’s different — you should avoid sex until you and any partners have been treated and your clinician confirms it’s safe, to prevent passing it on or being reinfected.
