Difficult Urinary Catheterization (DUC) occurs when the initial blind insertion meets resistance and catheter has been pulled back, advanced again and still meets resistance.


Consider using a visually guided catheterization system in high risk patients on the first attempts when:

  • Stricture disease
  • False passage
  • Acute urinary retention
  • Failed voiding
  • Enlarged prostate
  • Prostate surgery
  • BPH with obstruction
  • Artificial urinary sphincter
  • Lower urinary tract surgery
  • Prior difficult insertions
  • Anticoagulation therapy
  • Bladder instillation of BCG and chemotherapy
