UTI imaging results waiting

Overview

A urinary tract infection (UTI) is an infection in any part of your urinary system, such as your bladder or kidneys. Sometimes doctors recommend imaging tests—like ultrasound, CT scan, or MRI—to get a closer look at your urinary tract. Waiting for these results can feel stressful, but it’s a normal part of making sure you get the right care.

It is not common for everyone with a UTI to need imaging. Only about 1 in 10 people with a UTI have imaging, usually for recurrent infections or if there are signs of complications.

People who get recurrent UTIs, have blood in their urine, are pregnant, have kidney stones, or have had previous urinary tract problems are more likely to need imaging. It can affect both men and women, though women have more UTIs overall.

Symptoms

Common symptoms

• A strong, persistent urge to urinate
• A burning feeling when urinating
• Passing frequent, small amounts of urine
• Cloudy, dark, or strong-smelling urine
• Pelvic pain (in women) or rectal pain (in men)

Symptoms in children

• Fever without a clear cause
• Irritability or fussiness
• Poor feeding or vomiting
• Strong-smelling urine
• Bedwetting that was previously under control

Symptoms in older adults

• Confusion or sudden changes in mental state
• Low energy or weakness
• Loss of appetite
• Fever or chills (may be low-grade)
• Falls or unsteady walking

Causes

Main causes

• Bacteria (usually E. coli) from the digestive tract entering the urethra and moving up into the bladder
• Blockages in the urinary tract, like kidney stones or an enlarged prostate, that prevent urine from draining completely
• Structural problems in the urinary system (present from birth or after injury)
• Catheter use (a tube inserted into the bladder to drain urine)

Risk factors

• Being female (shorter urethra)
• Sexual activity
• Menopause (changes in the urinary tract lining)
• Poorly controlled diabetes
• Having a catheter
• Previous UTIs or family history of UTIs

When to see a doctor

See a doctor urgently if:

• If you have a high fever (over 38°C or 100.4°F) or chills
• If you have severe pain in your side or back
• If you are vomiting and cannot keep down fluids

Book a routine appointment if:

• If you have symptoms of a UTI that are mild and not getting better after a few days
• If you have recurrent UTIs (two or more in 6 months, or three or more in a year)
• If you notice blood in your urine and it does not go away

Diagnosis

A UTI is usually diagnosed with a urine test (dipstick or culture). Imaging is added when there are concerns about complicated infections, structural problems, or if the infection does not respond to antibiotics.

Tests that may be done

• Urine dipstick test (checks for signs of infection like nitrites and white blood cells)
• Urine culture (grows any bacteria to identify the exact germ)
• Ultrasound of the kidneys and bladder (uses sound waves to create images)
• CT scan (a series of X-ray images to see detailed views of the urinary tract)
• MRI (uses magnets and radio waves for very detailed images, sometimes used if CT is not suitable)

What to expect at your appointment

If you are waiting for imaging results, your doctor has likely ordered a scan to look for possible causes of your UTI. You may have an ultrasound, which is painless and takes about 30 minutes. For a CT scan, you might need to drink a contrast liquid or have it injected into a vein. These tests are done in a hospital or radiology clinic. Results usually arrive within a few days, but urgent results may be available sooner. Your doctor will call you or schedule a follow-up to discuss them.

Treatment

Treatment for a UTI usually starts with a short course of antibiotics to clear the infection. Imaging results help guide further treatment if there is an underlying cause, such as a kidney stone or a structural issue.

Self-care at home

• Drink plenty of water (aim for 6–8 glasses a day) to help flush out bacteria
• Urinate frequently and when you feel the urge—do not hold it in
• Use a hot water bottle on your lower abdomen or back to ease discomfort
• Avoid caffeine, alcohol, and spicy foods as they can irritate the bladder

Medical treatments

Your doctor will prescribe a course of antibiotics to treat the infection. It is important to take the entire course even if you feel better. For recurrent UTIs, your doctor may recommend a low-dose antibiotic taken daily or after sexual activity. If imaging shows a blockage like a kidney stone, you may need a procedure to remove it. Always discuss any treatment options with your healthcare provider.

When is surgery considered?

Surgery is rarely needed for a simple UTI. However, if imaging reveals a large kidney stone, an abscess, or a structural problem that does not resolve on its own, a surgical procedure (such as lithotripsy to break up stones or a minor operation to correct a blockage) may be recommended.

Living with this condition

While waiting for results and during treatment, focus on rest and hydration. Most people recover from a UTI without long-term effects. If you have recurrent UTIs, you may need to adjust some habits.

Lifestyle tips

• Urinate right after sexual intercourse to flush out any bacteria
• Wipe from front to back after using the toilet
• Wear cotton underwear and avoid tight clothing
• Stay well hydrated throughout the day

Diet and exercise

Drink plenty of water. Some people find that avoiding caffeine, alcohol, and acidic foods (like citrus and tomatoes) helps reduce bladder irritation. There is no special diet proven to prevent UTIs, but a balanced diet supports your immune system. Gentle exercise like walking is fine as long as you feel up to it.

Mental health and emotional wellbeing

Waiting for imaging results can cause worry, especially if you are in pain or have had infections before. It is normal to feel anxious. Try to talk to a friend or family member, or write down questions to ask your doctor. If anxiety becomes overwhelming, reach out to your healthcare provider for support.

Prevention

You can lower your risk of UTIs with good hygiene and lifestyle habits. Not all UTIs can be prevented, but these steps help. While waiting for imaging results, continue these practices to avoid further infections.

Vaccines

There is no vaccine available for UTIs at this time. Researchers are working on it, but it is not yet in use.

Screening programmes

Routine screening for UTIs is not recommended for most people. If you have repeated infections, your doctor may suggest regular urine tests to catch them early.

Complications

If left untreated

• Kidney infection (pyelonephritis) – can cause permanent kidney damage
• Sepsis – a life-threatening infection that spreads through the blood
• In pregnancy, untreated UTIs can increase the risk of low birth weight or preterm delivery
• Recurring infections that become harder to treat

Long-term outlook

Most UTIs are easily treated with antibiotics and cause no lasting problems. Even when imaging is needed, the outlook is very good with proper care. Your healthcare team will guide you through the process, and the results will help make sure you get the right treatment. Early treatment usually leads to a full recovery.
