Urinary Tract Infection (UTI)

Gambaran umum

A urinary tract infection (UTI) is an infection in any part of your urinary system, which includes the kidneys, ureters, bladder, and urethra. Most UTIs affect the lower urinary tract — the bladder and the urethra.

Yes, UTIs are one of the most common bacterial infections. About 50-60% of women will have at least one UTI in their lifetime.

Anyone can get a UTI, but they are much more common in women. Other groups at higher risk include older adults, people with diabetes, those who use a urinary catheter, and people with a suppressed immune system.

Gejala

Gejala umum

• A strong, persistent urge to urinate (urgency)
• A burning sensation or pain when urinating (dysuria)
• Passing frequent, small amounts of urine
• Cloudy, dark, or strong-smelling urine
• Pelvic pain or pressure, especially in women

Gejala pada anak-anak

• Fever (sometimes without other symptoms)
• Irritability or unexplained fussiness
• Poor feeding or vomiting
• Foul-smelling urine

Gejala pada lansia

• Sudden confusion or delirium
• Agitation or restlessness
• Change in behaviour
• Lower back pain or abdominal discomfort

Penyebab

Penyebab utama

• Bacteria — most commonly Escherichia coli (E. coli) from the digestive tract — entering the urethra and travelling up into the urinary system.
• Sometimes other bacteria or, rarely, fungi can cause UTIs.

Faktor risiko

• Being female (shorter urethra makes it easier for bacteria to reach the bladder)
• Sexual activity (can introduce bacteria into the urinary tract)
• Using a urinary catheter
• Menopause (changes in the urinary tract lining)
• Diabetes (especially if blood sugar is poorly controlled)
• A suppressed immune system
• Previous UTIs
• Abnormalities in the urinary tract that block urine flow

Kapan harus ke dokter

Segera temui dokter jika:

• If you have any symptoms of a kidney infection (such as high fever, chills, back pain, or vomiting)
• If you are pregnant and have UTI symptoms
• If you have blood in your urine

Buat janji temu rutin jika:

• If you have typical UTI symptoms for the first time or if symptoms last more than a day or two
• If you have recurrent UTIs (two or more in six months)
• If you are a man with UTI symptoms (UTIs are less common in men and may need more thorough investigation)

Diagnosis

Your doctor will ask about your symptoms and medical history, and may perform a simple urine test to check for signs of infection.

Tes yang mungkin dilakukan

• Urinalysis – a test strip dipped into your urine checks for white blood cells, nitrites, and other signs of infection.
• Urine culture – a sample of urine is sent to a lab to identify the exact bacteria causing the infection and which antibiotics will work best (usually only needed for recurrent or complicated UTIs).
• Imaging (ultrasound, CT scan) – rarely needed, but may be done if you have frequent kidney infections or a structural problem.

Apa yang diharapkan saat janji temu

The process is quick and painless. You will be asked to provide a clean catch urine sample in a sterile cup. Sometimes the doctor will also do a quick physical exam. Results from a simple urine test are often available within minutes. If a culture is needed, it may take 24–48 hours.

Perawatan

UTIs are usually treated with antibiotics. Most uncomplicated UTIs respond well to a short course (3–5 days). It is very important to finish the full course of antibiotics even if you feel better.

Perawatan mandiri di rumah

• Drink plenty of water (6–8 glasses a day) to help flush bacteria out of your urinary tract.
• Urinate often and completely — don't hold it in.
• Use a heating pad on your lower abdomen or back to ease pain.
• Avoid irritants like caffeine, alcohol, spicy foods, and nicotine, which can make symptoms worse.
• Take an over-the-counter pain reliever (like paracetamol or ibuprofen) for discomfort — always follow the label and consult your doctor if you're unsure.

Perawatan medis

Your doctor will prescribe an antibiotic that is appropriate for the type of bacteria causing your infection. The choice of antibiotic depends on your allergy history, local resistance patterns, and whether the infection is simple or complicated. A standard course usually lasts 3 to 7 days. For recurrent UTIs, your doctor may recommend a longer or different treatment plan, sometimes including a low-dose antibiotic taken for several months.

Kapan operasi dipertimbangkan?

Surgery is rarely needed for UTIs. It may be considered if there is a structural problem in the urinary tract (such as a blockage or abnormal narrowing) that keeps coming back. Your doctor will discuss this option if it applies to you.

Hidup dengan kondisi ini

Once you start treatment, symptoms usually improve within a few days. Continue to drink plenty of water and maintain good bathroom habits. If you have recurrent UTIs, keep a symptom diary to share with your doctor — this can help find patterns and triggers.

Tips gaya hidup

• Urinate as soon as you feel the urge — don't delay.
• Always wipe from front to back after using the toilet to prevent bacteria from the anal area reaching the urethra.
• Wear cotton underwear and loose clothing to keep the area dry.
• Avoid using scented soaps, bubble baths, or feminine hygiene sprays.

Diet dan olahraga

There is no specific diet to treat a UTI, but staying hydrated with water is key. Some people find that drinking cranberry juice (unsweetened) may help prevent UTIs, but it is not a treatment. Avoid bladder irritants like caffeine and alcohol while you have symptoms. Gentle exercise is fine, but rest if you feel unwell.

Kesehatan mental dan kesejahteraan emosional

Recurrent UTIs can be frustrating and uncomfortable, and they may cause stress or anxiety about flare-ups. It is important to talk to your doctor about prevention strategies. Remember that this is a common medical problem, and effective treatments are available.

Pencegahan

While not all UTIs can be prevented, many lifestyle measures can reduce your risk. These include staying well hydrated, urinating after sexual activity, and practising good bathroom hygiene.

Vaksin

There is no standard vaccine for UTIs. Researchers are studying potential vaccines, but none are widely available yet.

Program skrining

There is no routine screening for UTIs in healthy people. If you have frequent UTIs, your doctor may recommend regular urine tests to check for bacteria without symptoms (asymptomatic bacteriuria), especially if you are pregnant.

Komplikasi

Jika tidak diobati

• The infection can spread from the bladder to one or both kidneys (pyelonephritis), which is more serious and may require hospital treatment.
• A kidney infection can cause permanent kidney damage if not treated promptly.
• In rare cases, the infection can spread to the bloodstream (sepsis), which is life-threatening and requires immediate emergency care.

Prospek jangka panjang

Most UTIs are treated quickly and effectively. With proper antibiotics, symptoms usually resolve within a few days. Even if you have recurrent UTIs, there are good strategies to reduce their frequency. Simple steps can help you manage and prevent future infections. See your healthcare provider if UTIs keep coming back.
