Other considerations

Risks associated with catheterization include:

  • Urethral trauma and bleeding from inappropriate catheter size or use of force.
  • Urinary tract infections related to poor sterile technique or long-term catheterization.
  • Bladder spasms and pain  

Choosing the appropriate catheter depends on

  • The size of the patient’s urethral canal
  • The expected duration of catheterization (e.g. intermittent or indwelling)
  • Knowledge of any allergies to latex or plastic.
  • The indications for catheterizing the patient (i.e. clot retention, child, bladder instillation).
