Can UTI Happen After Prostate Surgery?

Yes. A UTI can occur after prostate surgery, particularly during the early recovery period when a urinary catheter is used or when the urinary tract has been recently instrumented. However, some burning, urgency, frequency, or blood in the urine can also occur temporarily after surgery, so symptoms need to be assessed in the context of normal postoperative recovery.

Prostate procedures, including surgeries performed for an enlarged prostate, involve the lower urinary tract and may require temporary catheterisation. These factors can increase the possibility of developing a urinary infection during recovery.

A UTI after prostate surgery may be associated with:

• Temporary urinary catheter use
• Instrumentation of the urinary tract
• Difficulty emptying the bladder during recovery
• Pre-existing bacteria in the urinary tract
• Persistent urinary obstruction or retention
• Other underlying urinary tract conditions

What symptoms may indicate a UTI?

Possible symptoms include:

• Burning or pain while urinating
• Increased urinary frequency or urgency
• Cloudy or foul-smelling urine
• Lower abdominal or pelvic discomfort
• Fever or chills
• Back or side pain
• Feeling unusually weak or unwell

Some urinary symptoms are expected for a period after certain prostate procedures, so the presence of a symptom alone does not necessarily mean there is an infection. Fever, worsening symptoms, significant pain, or systemic symptoms should be evaluated promptly.

How is a UTI diagnosed after prostate surgery?

When infection is suspected, the doctor may recommend:

• Urinalysis
• Urine culture
• Blood tests if there are signs of a systemic infection
• Assessment of bladder emptying if there is difficulty passing urine
• Imaging when obstruction, stones, or another complication is suspected

A urine culture can help identify the responsible bacteria and guide antibiotic selection.

Does a UTI mean prostate surgery has failed?

No. Developing a UTI after prostate surgery does not automatically mean that the procedure was unsuccessful. Infection and normal postoperative urinary symptoms can overlap.

However, persistent difficulty passing urine, recurrent infections, or worsening urinary flow may require assessment for problems such as urinary retention, infection, or persistent/recurrent obstruction.

How can the risk be reduced?

Following postoperative instructions, maintaining appropriate hydration, taking prescribed medicines correctly, and following catheter-care instructions can help reduce complications. Unnecessary antibiotics should be avoided because they can contribute to antibiotic resistance.

SCI International Hospital

At SCI International Hospital, Dr. Gautam Banga evaluates patients who develop urinary symptoms after prostate surgery to distinguish normal postoperative changes from infection or other complications. When appropriate, assessment may include urine culture, evaluation of bladder emptying, and investigation for urinary retention, obstruction, or other urological problems.
