Can UTI Occur After Urinary Catheter Use?

Yes. Urinary catheter use can increase the risk of a UTI, particularly when a catheter remains in place for an extended period. Bacteria can enter the urinary tract through or around the catheter, and the risk generally increases with longer catheter use.

A urinary catheter is a tube used to drain urine from the bladder when a person cannot empty the bladder normally. Although catheters can be medically necessary, they can also increase the risk of infection because they provide a pathway for bacteria to enter the urinary tract.

A catheter-associated UTI may be more likely when:

• The catheter remains in place for a prolonged period.
• There is repeated catheter insertion or manipulation.
• The bladder does not empty normally.
• There is an underlying urinary obstruction or abnormality.
• The patient has previously experienced urinary infections.
• Catheter care or hygiene is inadequate.

Symptoms can include burning or discomfort, frequent or urgent urination after catheter removal, cloudy or bloody urine, lower abdominal discomfort, fever, chills, or back/side pain. However, the presence of bacteria in urine in a catheterised patient does not always mean that a symptomatic UTI is present, so symptoms and clinical findings need to be considered together.

If a catheterised patient develops fever, chills, significant weakness, back or side pain, vomiting, confusion, or other signs of systemic infection, prompt medical assessment is important.

Treatment depends on whether there is a symptomatic catheter-associated UTI and how severe the infection is. Doctors may recommend urine testing and culture, and catheter replacement or removal may be considered when appropriate. Antibiotics should be selected based on the clinical situation and, when indicated, culture results rather than taken without medical advice.

At SCI International Hospital, Dr. Gautam Banga evaluates urinary infections occurring after catheter use while also looking for the reason catheterisation was required. If recurrent infections are associated with urinary retention, enlarged prostate, urethral stricture, obstruction, or another urinary problem, addressing the underlying condition may help reduce future infection risk.
