Living Well with a Long-Term Catheter: A Urologist’s Honest Guide to Urethral Catheters, Supra-pubic Catheters / SPCs, and Intermittent Self Catheterisation

By Prof. Keskin, Consultant Urological Surgeon

If you or a loved one has recently been told that you need a long-term urinary catheter, it is completely normal to feel overwhelmed, anxious, or frustrated. Many of my patients walk into my clinic feeling as though their independence has been cut short by a piece of plastic tubing.

The first thing I tell my patients is this: a catheter is a tool designed to protect your kidneys, relieve your bladder, and give you back control of your life. With the right routine and information, thousands of people live active, comfortable, and fulfilling lives with long-term urinary drainage.

In this guide, I will answer the most common questions patients ask—and search for online—regarding catheter management, switching to a suprapubic catheter (SPC), and exploring alternatives like intermittent catheterisation.

"How do I actually live day-to-day with a long-term urethral catheter?"

A long-term urethral catheter enters the bladder through the urethra (the natural tube you urinate through). The catheter is held safely inside the bladder by a tiny balloon inflated with sterile water.

Here are the essential rules for keeping your urethral catheter trouble-free:

1. Master the Fluid Balance

• Drink 2 to 3 litres of fluid daily (mostly water, but clear broths and herbal teas count).

  
  

• Why it matters: Good fluid intake constantly flushes the bladder, preventing mineral build-up (encrustation) that leads to blockages and reducing the risk of urinary tract infections (UTIs).

  
  

• Rule of thumb: Your urine should be pale straw-colored. If it looks dark or concentrated, you need to drink more water.

  
  

2. Hygiene and Daily Cleaning

• Wash your hands thoroughly with soap and warm water before and after touching any part of your catheter system.

  
  

• Clean the entry point daily during your bath or shower using mild soap and water. Always wash away from your body along the tubing to avoid introducing bacteria into the bladder.

  
  

• Avoid using scented bath oils, talcum powder, or harsh antiseptics around the catheter site.

  
  

3. Managing Day Bags, Night Bags, and Catheter Valves

• Day Leg Bags: Attached directly to your catheter and secured to your thigh or calf using comfortable elastic straps or sleeves. Empty the leg bag into the toilet when it is around half to two-thirds full so the weight does not pull on your bladder.

  
  

• Night Drainage Bags: At night, connect a larger night bag directly to the tap at the bottom of your leg bag (keeping the tap open). Place the night bag on a stand on the floor lower than your bed so gravity can draw urine down.

  
  

• Catheter Valves (Bag-Free Option): Some patients use a catheter valve instead of a leg bag. The valve stays closed to let your bladder store urine naturally and is opened over a toilet every 3–4 hours to empty. Note: Catheter valves are only suitable if your bladder can safely store urine without pressure building up toward your kidneys.

  
  

"What is Intermittent Catheterisation (ISC), and is it an option for me?"

Patients frequently ask: "Do I have to keep a bag attached to me all the time?"

The answer is often no. Clean Intermittent Catheterisation (ISC)—sometimes called intermittent self-catheterisation—is considered the gold standard for bladder emptying whenever medically feasible.

• How it works: Instead of leaving a catheter tube in place 24/7, you insert a small, pre-lubricated disposable catheter into your urethra 4 to 6 times a day to drain your bladder completely. Once emptied, the tube is removed and thrown away.

  
  

• Why it is popular:

  
  

  • You do not carry a collection bag or have tubing attached to your leg.

    
    

  • You retain full sexual function and bodily privacy.

    
    

  • It carries a lower risk of long-term urethral damage and fewer persistent bladder infections than a permanent catheter.

    
    

• Who it works for: Patients with good hand dexterity who can easily reach their urethra and are willing to follow a regular routine. If hand function or anatomy makes self-insertion difficult, an indwelling continuous catheter remains the safest path.

  
  

"Should I switch to a Suprapubic Catheter (SPC)?"

If intermittent catheterisation is not suitable, patients using a long-term urethral catheter often reach a point where they ask about an SPC (Suprapubic Catheter).

What is an SPC?

A suprapubic catheter drains urine from the bladder through a small incision made in the lower abdomen (just below the belly button / pubic hairline) rather than through the urethra. The initial procedure is quick, routine, and typically performed under local anaesthetic or light sedation.

          /=============\                         /=============\

                 |                                       |
                 | (Tube through natural                 += = = = = = (Tube through lower

                 v                                       

When should you consider an SPC?

In urological practice, we often recommend discussing an SPC switch if you experience:

1. Persistent urethral discomfort or pain from the tube rubbing against sensitive tissue.

   
   

2. Urethral strictures or tissue damage (erosion/trauma) caused by long-term urethral tubes.

   
   

3. Desire to maintain an active sex life without catheter interference.

   
   

4. Wheelchair use or mobility impairments, where seating pressure makes urethral catheters uncomfortable or difficult to manage hygiene-wise.

   
   

5. Recurrent catheter blockages or leakage around the urethral tube (bypassing).

   
   

What are the Ups and Downs of an SPC vs. Urethral Catheter?

Every catheter option has its unique advantages and trade-offs. Here is a clear breakdown to help you weigh the decision:

Feature / Aspect	Urethral Catheter	Suprapubic Catheter (SPC)
Insertion Site	Natural opening (urethra).	Small opening in lower belly wall.
Comfort & Mobility	Can cause urethral soreness, tugging, or tissue erosion over time.	Generally much more comfortable, especially when sitting or walking.
Hygiene & Cleaning	Harder to keep clean around genital area; risk of fecal contamination.	Easy to see, clean, and dress on the flat abdomen.
Sexual Intimacy	Complex; tube must be folded back or removed during sex.	Urethra remains entirely free, making intimate relations much easier.
Catheter Changes	Can be uncomfortable or painful to insert via the urethra.	Simple, quick 5-minute tube swap through the established abdominal tract.
Initial Setup	No surgery required; inserted through existing anatomy.	Requires a minor surgical procedure to create the small abdominal tract.
Downsides / Risks	Higher risk of urethral damage, strictures, and irritation.	Site can leak fluid or develop overgrowth of pink skin tissue (granulation tissue).

"What problems should I watch out for?"

Whether you have a urethral catheter or an SPC, knowing when to self-manage and when to call your healthcare team is key to staying safe.

Common Issues and Solutions

• Bladder Spasms (Tummy Cramps): Feeling like your bladder is trying to squeeze out the catheter is very common. This is usually caused by the balloon touching the inside of the bladder. Solution: Make sure the tube is not pulling tight. If spasms persist, your doctor can prescribe medication to relax the bladder muscle.

  
  

• Bypassing (Urine Leaking Around the Tube): Often caused by bladder spasms, a kinked tube, or a temporary blockage. Check that your tubing is straight and the collection bag is below bladder level.

  
  

• Cloudy or Smelly Urine: Almost everyone with a long-term catheter has harmless bacteria living in the bladder (known as colonization). You only need antibiotics if you develop active symptoms of infection.

  
  

🚨 Red Flag Symptoms: Call Your Nurse or Doctor Immediately If:

• No urine has drained into your bag for 4 hours, and you feel full or uncomfortable.

  
  

• You develop a fever, chills, shivering, or severe low back/flank pain.

  
  

• Your urine turns bright red with large blood clots.

  
  

• There is continuous leakage, redness, swelling, or pus around an SPC insertion site.

  
  

• Your catheter falls out completely. (Note: An SPC tract can start to close within hours, so an emergency replacement is essential!)

  
  

Final Thoughts from Prof. Keskin

Living with a long-term catheter requires a period of physical and emotional adjustment. However, having a catheter should not isolate you from your normal routine, hobbies, or loved ones.

If your current urethral catheter is causing recurring pain, recurrent infections, or restriction to your lifestyle, please speak open-mindedly with your urologist or district nurse about whether an SPC or Intermittent Catheterisationcould offer a cleaner, more comfortable long-term solution.

Stay well-hydrated, keep your routine clean, and never hesitate to reach out to your clinical team when something feels off!
