Urinary Tract Infection (UTI)

Overview

A urinary tract infection (UTI) is an infection anywhere in the urinary tract — most commonly the bladder (cystitis), and sometimes the kidneys (pyelonephritis). It is among the commonest infections seen in general practice, particularly in women, and usually presents with burning, frequency, urgency and sometimes cloudiness or blood in the urine. Most UTIs respond quickly to the right antibiotic, but certain features — fever, back pain, pregnancy, diabetes or recurrent infection — need closer attention. This is the main disease-focused page; Burning Urination, Recurrent Urinary Tract Infection and Cloudy Urine link here for the more specific angles.

Symptoms

• Burning or pain when passing urine.
• Needing to pass urine often and urgently, sometimes in small amounts.
• Cloudy, strong-smelling or blood-tinged urine.
• Lower abdominal discomfort or pressure.
• Fever, chills, back or flank pain, nausea or vomiting when the kidneys are involved.

Common causes and risk factors

• Bacteria entering the urinary tract, most often from the bowel.
• Women are at higher risk due to a shorter urethra.
• Diabetes, which raises infection risk and alters urine sugar.
• An enlarged prostate or urinary obstruction causing incomplete emptying.
• Kidney or bladder stones.
• Pregnancy, catheter use, and poor urinary hygiene.
• Menopause-related changes in the urinary tract.

Evaluation and investigations

Evaluation is based on the symptom pattern and a urine test. Urine routine and microscopy shows pus cells, blood or bacteria; a urine culture identifies the organism and the antibiotics that will work. Blood sugar is checked when diabetes is a possibility, and kidney function when kidney involvement is suspected. An ultrasound is arranged for recurrent infection, suspected stones or obstruction. See Abnormal Urine Test Results.

Management overview

A confirmed UTI is treated with the appropriate antibiotic, guided by culture where possible, and the urine is re-checked after treatment to confirm clearance. Adequate hydration and symptomatic measures support recovery. When an underlying cause is present — diabetes, obstruction or stones — it is treated to prevent recurrence. Repeated antibiotic courses without investigation are avoided. See Recurrent Urinary Tract Infection.

Follow-up and monitoring

A follow-up urine test confirms clearance. For those with recurrent infection, diabetes or structural causes, a structured plan prevents recurrence and catches relapse early. See Recurrent Urinary Tract Infection.

Warning signs — seek prompt care

• Fever, chills, back or flank pain with urinary symptoms — possible kidney infection.
• Visible blood in the urine.
• Symptoms not improving within a day or two of starting antibiotic.
• UTI in pregnancy, diabetes, or with a known kidney problem — needs prompt assessment.
• Confusion or drowsiness with a urinary infection in an older person — urgent.
