Catheterization plays a vital role in modern medical care, providing essential bladder management for patients with various urological conditions. Two primary catheterization methods dominate clinical practice: intermittent catheter vs. indwelling catheter approaches. Each method serves distinct purposes and offers unique advantages depending on patient needs and clinical circumstances.

Clinical Indications and Contraindications

AspectIntermittent CatheterIndwelling Catheter
IndicationsNeurogenic bladder dysfunction, non-neurogenic urinary retention, post-operative temporary urinary retention, patients who can self-catheterize or have caregiver assistanceAcute urinary retention requiring continuous drainage, critically ill patients requiring urine output monitoring, perioperative use, patients unable to perform intermittent catheterization
ContraindicationsHigh intravesical pressure requiring continuous drainage to prevent renal damage; poor manual dexterity without a suitable caregiver; urethral trauma; acute urethritis or prostatitisKnown or suspected urethral injury (absolute contraindication); acute prostatitis; severe urethral stricture or obstruction

Understanding Indwelling Catheter

What are indwelling catheters? Indwelling catheters, commonly referred to as Foley catheters, are designed to remain in the bladder continuously for extended periods. The catheter tip contains an inflatable balloon that secures it in place inside the bladder. During insertion, the catheter is passed through the urethra into the bladder, allowing urine to drain continuously into a closed collection bag.

Understanding Intermittent Catheter

Intermittent catheterization, also known as “in-and-out catheterization” or clean intermittent catheterization (CIC), is a type of short-term catheterization method. Patients or caregivers insert the intermittent catheter into the bladder as needed to drain urine, then immediately remove it.

Advantages, as the “Gold Standard”:

The Current Association of French Urologists, the European Association of Urology (EAU), the American Urological Association (AUA), and the Healthcare Infection Control Practices Advisory Committee (HICPAC) guidelines recommend Intermittent Catheterization (IC) over other catheter-based options.
Reports indicate that intermittent catheterization reduces infection risk compared to indwelling catheterization, with post-operative short-term use potentially decreasing infection risk by around 20%.[1,2] The multidrug-resistant bacterial infection rate is only 0.7% with intermittent catheterization, whereas the occurrence of indwelling catheterization can reach 2.6%[3].

Intermittent Catheter vs. Indwelling Catheter

AspectIntermittent CatheterIndwelling Catheter
PurposeIntermittent Catheterization (IC) Continuous bladder drainage
Method of OperationInsert–drain–remove cycle performed 4–6 times daily under clean or sterile techniqueSingle insertion with an inflatable balloon retaining the catheter in the bladder; attached to a closed drainage bag
Catheter MaterialHydrophilic-coated thermoplastic polyurethane (TPU), PVC, silicone, latex, or vinylLatex or medical-grade silicone, often with antimicrobial or hydrophilic coatings
Infection RiskLow infection risk; studies show a reduced incidence of UTIHigh infection risk; daily UTI risk increases by ~5%
Nursing PointsEmphasis on patient/caregiver training in clean technique, adherence to scheduled catheterizationsRequires strict aseptic insertion, maintenance of a closed drainage system, routine bag emptying, and catheter changes every 2–4 weeks
CostLower cost per useHigher cumulative costs over time due to complications and increased HCRU

Intermittent Catheter

Advantages:

—Significantly reduces infection rates

—Preserves bladder function

—Improves patient independence and quality of life

—More cost-effective in the long term

Disadvantages:

—Requires multiple daily procedures by the patient or caregiver
—Not suitable for individuals with limited manual dexterity or cognitive impairment

Indwelling Catheter

Advantages:

—Does not require repeated procedures by the patient
—Suitable for critically ill or immobile patients
—Provides immediate relief in cases of acute urinary retention

Disadvantages:

—Higher risk of infection and complications

—Occupancy of long-term nursing and healthcare resources 

How to Choose the Right Catheter for Your Patient?

When selecting a urinary catheter, a comprehensive assessment is required:

  1. Patient’s cognitive ability and manual dexterity for self-catheterization
  2. Underlying condition severity and duration of need
  3. Infection risk factors and immune status
  4. Patient lifestyle and independence goals
