A catheter routine may feel familiar until something suddenly changes. Urine may stop draining normally, discomfort may increase, leakage may appear, or the catheter may no longer seem to be in its usual position.

When that happens, it isn’t always easy to tell whether you’re seeing a minor equipment issue or a possible complication that requires medical attention. Learning common catheter complication warning signs can help you recognize unexpected changes and contact the appropriate healthcare professional sooner.

What Are the Early Warning Signs of Catheter Complications?

Potential warning signs include:

  • Little or no urine drainage
  • Leakage around an indwelling catheter
  • New or increasing pain
  • Bladder pressure or fullness
  • Fever or chills
  • Blood in the urine
  • Visible blood clots or significant debris
  • New skin irritation near the catheter or securement area
  • A catheter that appears damaged, displaced, or out of position
  • An unexpected change in the person’s overall condition

A symptom can mean different things depending on the type of catheter you use, your health history, and what other symptoms you’re experiencing.

For example, leakage may be related to a blockage, bladder spasms, constipation, or a tubing issue. Cloudy urine may deserve attention, but it doesn’t confirm an infection by itself. A healthcare professional can assess the full pattern and determine the appropriate next step.

What May Point to a Catheter-Associated UTI?

A catheter-associated urinary tract infection, or CAUTI, occurs when germs enter the urinary tract through a urinary catheter and cause an infection. The infection may affect the urethra, bladder, ureters, or kidneys.

Possible symptoms that warrant medical guidance may include:

  • Fever
  • Chills or feeling hot, cold, or shivery
  • Pain below the stomach or around the groin
  • Lower abdominal or pelvic discomfort
  • Flank or back pain
  • Burning or pain when urinating, when applicable
  • Increased urinary frequency after intermittent catheterization
  • New confusion or a marked change in condition

Cloudy urine, dark urine, sediment, or a strong odor may deserve attention, especially when they represent a clear change. However, appearance or odor alone can’t diagnose a UTI. Contact your healthcare provider if you develop symptoms of an infection or are unsure how to interpret a change.

How Can You Tell if a Catheter May Be Blocked?

A catheter may be blocked when little or no urine reaches the drainage bag, particularly when reduced drainage occurs with bladder pressure, increasing discomfort, or leakage around an indwelling catheter.

Possible blocked-catheter warning signs include:

  • Little or no urine in the drainage bag
  • Increasing bladder fullness or pressure
  • Lower abdominal discomfort
  • Leakage around the catheter
  • Visible kinks or twists in the tubing
  • Blood clots or large pieces of debris in the tubing
  • A sudden change from the person’s usual drainage pattern

If an indwelling catheter isn’t draining, look for an obvious kink or twist in the visible tubing and make sure the collection bag remains below bladder level. The CDC recommends keeping the bag below the bladder and avoiding twisting or kinking the tubing.

If drainage doesn’t resume, discomfort is increasing, or you notice blood clots or significant debris, contact a healthcare professional promptly.

Don’t flush, remove, reposition internally, or manipulate an indwelling catheter unless a qualified healthcare professional has specifically instructed you to do so.

Why Is Urine Leaking Around an Indwelling Catheter?

Urine leaking around an indwelling catheter is sometimes called bypassing. It may be associated with:

  • A partial or complete blockage
  • Bladder spasms
  • Constipation
  • Kinked or twisted tubing
  • Positioning or drainage problems
  • Catheter movement
  • Another issue that requires clinical assessment

Check the visible tubing for obvious kinks and confirm that the drainage bag is positioned below the bladder. Persistent or recurring leakage should be reported to a healthcare provider, particularly when it occurs with pain, fever, reduced drainage, bleeding, or increasing bladder pressure.

Don’t attempt to fix ongoing leakage by pulling on, advancing, removing, or replacing an indwelling catheter unless you’re following specific instructions from your healthcare professional.

When Do Pain, Spasms, or Bleeding Need Attention?

Some people experience irritation with catheter use, particularly after intermittent catheterization or a catheter change. However, new, recurring, or worsening discomfort should be discussed with a healthcare professional.

Contact your healthcare provider about increasing lower abdominal, pelvic, urethral, flank, or back pain, frequent or painful bladder spasms, pain that doesn’t improve, bleeding that continues or worsens, visible blood clots, and blood accompanied by fever, chills, reduced drainage, or significant discomfort.

A small amount of blood may sometimes appear after irritation or catheterization, but only a healthcare professional can determine whether bleeding is expected in your situation. Persistent bleeding, increasing blood, visible clots, or bleeding with other symptoms requires medical evaluation.

What Should You Do if a Catheter Becomes Dislodged?

If an indwelling or suprapubic catheter comes out or appears significantly displaced, contact your healthcare provider promptly and follow your clinician-directed emergency plan.

Don’t attempt to reinsert an indwelling or suprapubic catheter unless a qualified healthcare professional has specifically trained and instructed you to do so.

Seek more urgent care if catheter displacement occurs with:

  • Severe pain
  • Heavy bleeding
  • Inability to drain urine
  • Increasing abdominal or bladder discomfort
  • Fever, chills, confusion, or a marked decline in condition

People who use intermittent catheters should continue following the insertion technique and schedule provided by their care team. Contact the healthcare professional who oversees your catheter care if insertion suddenly becomes difficult, painful, or different from usual.
