Can bladder stones occur after urinary catheter use?

Yes, long-term or repeated urinary catheter use can be associated with bladder stone formation. Catheters may contribute to factors such as urinary infection, foreign-body irritation, and mineral buildup around the catheter. The risk is generally more relevant with long-term catheterization than with a short-term catheter used briefly after surgery.

A urinary catheter is a thin tube used to drain urine from the bladder when a person cannot empty it normally.

While short-term catheterization is commonly used after certain procedures, prolonged catheter use can increase the risk of urinary complications, including bladder stones.

How can a catheter contribute to bladder stones?

Several factors may contribute:

• Urinary infection: Long-term catheter use increases the risk of catheter-associated urinary tract infection.
• Foreign-body effect: The catheter can act as a surface around which mineral deposits may accumulate.
• Urine remaining in the bladder: Underlying bladder-emptying problems may continue even when a catheter is removed.
• Mineral buildup: Deposits can accumulate on or around the catheter over time.

Are bladder stones common after a short-term catheter?

Not necessarily.

A catheter used temporarily—for example, after bladder stone surgery or another procedure—does not mean that a bladder stone will develop.

The risk depends on factors such as:

• Duration of catheter use.
• Repeated catheterization.
• Urinary infection.
• Bladder function.
• Underlying urinary obstruction.
• Individual medical circumstances.

Does long-term catheterization increase the risk?

Yes. Long-term catheterization is more strongly associated with urinary complications than short-term catheter use.

People who require long-term catheter drainage may need regular medical follow-up to monitor their urinary health and catheter-related problems.

Can a catheter cause urinary tract infections?

Yes. Catheter use can increase the risk of urinary tract infection, particularly when the catheter remains in place for a prolonged period.

Symptoms that may require medical assessment include:

• Fever or chills.
• New or worsening urinary discomfort.
• Lower abdominal pain.
• Blood in the urine.
• Other changes in urinary symptoms.

Can catheter-related bladder stones be removed?

Yes, when treatment is clinically indicated.

The appropriate treatment depends on the size, number, and location of the stones and the patient's overall condition.

Endoscopic stone removal, such as cystolitholapaxy, may be appropriate for many patients.

Should the catheter be removed to prevent bladder stones?

Not always.

Some patients require long-term catheterization because of an underlying medical condition.

The decision to remove, replace, or change the type of catheter should be made by the treating healthcare professional.

If a patient no longer needs a catheter, the medical team can determine whether it can be safely discontinued.

What if a person develops repeated bladder stones while using a catheter?

Repeated stones should prompt evaluation for the underlying cause.

Your urologist may assess:

• Urinary infection.
• Bladder emptying.
• Catheter-related factors.
• Urinary obstruction.
• Bladder function.
• Stone composition.

Treating only the stone may not prevent recurrence if the underlying problem remains.

Can Bladder Stones Form Around a Catheter?

They can. Mineral deposits may accumulate on or around a long-term catheter, particularly when urinary infection or other risk factors are present.

If a catheter becomes blocked, encrusted, or repeatedly causes urinary problems, medical assessment is important.

Can Catheter Removal Prevent Future Bladder Stones?

It may reduce catheter-related risk when the catheter is no longer medically necessary, but it does not eliminate all causes of bladder stone formation.

If incomplete bladder emptying, urinary obstruction, or bladder dysfunction remains, those conditions may continue to contribute to stone formation.

When Should I See a Urologist?

Seek urological evaluation if you have:

• Recurrent bladder stones.
• Long-term catheter use with recurrent urinary problems.
• Catheter blockage.
• Blood in the urine.
• Recurrent urinary infections.
• Difficulty passing urine after catheter removal.
• Lower abdominal discomfort.
• New or worsening urinary symptoms.

Sudden inability to pass urine requires prompt medical attention.

SCI International Hospital

At SCI International Hospital, New Delhi, Dr. Gautam Banga, Senior Consultant Urologist and Andrologist, evaluates patients with bladder stones, urinary obstruction, recurrent urinary infections, enlarged prostate, urethral stricture, and bladder-related problems. Patients with recurrent stones or catheter-related urinary complications can be assessed to identify contributing factors and determine an appropriate treatment approach.
