Symptoms of a urine infection
- Burning or pain while passing urine
- Needing to pass urine often, or urgently, but only a little comes
- Cloudy or strong-smelling urine
- Pain low in the belly
- Blood in the urine
If the infection spreads to the kidney, you may also have fever, shivering, pain in the side or back, and vomiting. That needs treatment the same day.
When to see a urologist
- Infections that keep coming back
- Any urine infection in a man
- Infection with fever, back pain or blood in the urine
- Infection that does not clear with the right antibiotic
- Infection with a known stone, diabetes, or difficulty emptying the bladder
- Other urine problems, such as passing urine very often, a poor stream or discomfort that tests don't explain
Causes and risk factors
Most urine infections are caused by bacteria from the bowel that enter the urethra and travel up into the bladder. They are more likely with:
- Being a woman, because the urethra is short
- Not drinking enough water, or holding urine for long hours
- Sexual activity, especially new or frequent intercourse
- Menopause, when the protective tissues around the urethra become thinner
- Diabetes, especially when sugar is not well controlled
- Kidney or bladder stones, an enlarged prostate, or a narrowing of the urethra
- A urinary catheter, or a recent procedure on the urinary tract
- Constipation
Recurrent urine infections
Two or more infections in six months, or three or more in a year, are called recurrent urine infections. Taking a different antibiotic each time without a culture can lead to germs that resist common antibiotics. The doctor checks your culture reports, looks for a cause such as a stone or a bladder that does not empty, and agrees a prevention plan with you. Women with repeat infections can also read the female urology page.
What happens at your visit to the clinic
- The doctor asks about your symptoms, how often infections happen, which antibiotics you have taken, and your other health conditions.
- He examines you and reviews your earlier urine reports and scans.
- He arranges a urine culture, ideally before a new antibiotic is started, so the right medicine can be chosen.
- For repeat infections, he looks for a cause and explains how to lower the chance of the next one.
Tests the doctor may advise
- Urine routine test and urine culture
- Blood sugar and kidney function tests
- Ultrasound of the kidneys and bladder, including how much urine is left after passing urine
- Uroflowmetry in men, to check the flow
- For some repeat infections, a CT scan or a look inside the bladder with a thin telescope (cystoscopy)
The doctor will tell you which of these tests you need and where each one can be done.
Treatment options after evaluation
- The right antibiotic, chosen from the culture report where possible, taken for the full course.
- Treating the cause: a stone, a prostate problem, a narrowing of the urine passage, or a bladder that does not empty fully.
- Prevention: enough fluid, not holding urine for long, passing urine after sex, managing blood sugar, and treating constipation. For frequent infections, the doctor may discuss other preventive treatment.
Urine problems that are not infections
Burning, frequency and discomfort are not always caused by infection. If urine cultures keep coming back clear, the doctor looks for other causes, such as:
- An overactive bladder
- A stone near the bladder
- Prostate enlargement or inflammation in men
- A narrowing of the urethra
- Bladder pain syndrome, a long-standing bladder discomfort without infection
- Irritation from very concentrated urine, or from some foods and drinks
Antibiotics do not help these problems, which is why the cause needs to be found.
Preventing the next infection
- Drink enough water that your urine stays pale through the day
- Pass urine every three to four hours, and do not hold it for long
- Pass urine soon after sex
- Keep blood sugar under control if you have diabetes
- Treat constipation
- Women: wipe from front to back, and avoid scented washes and douches
When to go to an emergency department
- High fever, shivering or feeling very unwell with urinary symptoms
- Pain in the side or back with vomiting
- Not passing urine, or passing very little
- Confusion or drowsiness, especially in an older person
- Fever with urinary symptoms during pregnancy

Questions patients ask
Can I just take an antibiotic from the chemist?
It is better not to. Taking antibiotics without a urine test can hide the infection, breed resistant germs, and make the next infection harder to treat. A urine culture taken before the antibiotic starts shows which medicine will work.
How many infections count as "recurrent"?
Doctors usually call it recurrent if you have two infections in six months or three in a year. At that point it is worth looking for a cause such as a stone, incomplete emptying of the bladder or, in men, a prostate problem.
Is a urine infection in a man different?
Yes. Urine infections are less common in men, so the doctor usually looks for a reason, such as the prostate, a narrowing of the urine passage, or a stone.
Does drinking more water help?
Drinking enough fluid to keep your urine pale helps flush the bladder and can lower the chance of repeat infections. It does not replace the right antibiotic for an infection you already have.
Why does the doctor ask for a urine culture?
A culture grows the germ from your urine and shows which antibiotics work against it. This matters most for repeat infections, where the germ may resist common antibiotics.
Can a urine infection affect the kidneys?
Yes, if it spreads upward. Fever, shivering, back or side pain and vomiting with urine symptoms can mean a kidney infection, which needs treatment the same day.
Do cranberry products prevent infections?
The evidence is mixed. Some women with repeat infections find them helpful, but they do not treat an active infection. Ask the doctor before relying on them.
