      2. Bacteriuria
        1. Single intermittent catheterization: 20% of elderly
        2. Bacteriuria occurs in most patients in 2-3 weeks

        1. Hip Fracture repair
        2. Total abdominal Hysterectomy
    2. External Catheter (Condom catheter)
      1. Incontinent men without obstructive uropathy
      2. More comfortable than indwelling catheters
      3. Lower Incidence of bacteruria
      4. Skin breakdown may occur
    3. Suprapubic Catheterization (short-term post-operative)
      1. Lower infection risk
      2. Improved comfort and convenience
      3. Risks
        1. Cellulitis
        2. Hematoma or leakage at puncture site
        3. Urethral prolapse
  7. Catheter Characteristics
    1. Catheter Material
      1. Latex: Long-term catheterization
      2. Silastic: Short-term catheterization or Latex Allergy
    2. Minocycline and Rifampin impregnated catheters
      1. May reduce bacteriuria for up to 2 weeks
      2. Reference
        1. Darouiche (1999) Urology 54:976
    3. Catheter size
      1. Narrowest, softest efective tube
        1. Range: 12F (smallest) to 18F (largest)
        2. Most common: 14F to 16F
      2. Balloon size: 5 ml balloon with 5-10 ml fluid
  8. Management: Urinary Tract Infection
    1. See Urinary Catheter associated Urinary Tract Infection
    2. See Prevention of Urinary Catheter associated UTI
  9. Management: General
    1. Urinary Catheter Blockage
      1. Maximize patient hydration
      2. Consider Methanamine preparations to prevent blockage
      3. Consider bladder irrigation
      4. Change catheter before expected time to obstruction
      5. Change catheter if no urine flow in 4 to 8 hours
      6. Evaluate for UTI for more frequent catheter blockage
    2. Urinary Catheter leakage
      1. Do not increase catheter diameter
      2. Evaluate for catheter blockage (above)
      3. Evaluate for Urinary Catheter associated UTI
      4. Consider Bladder Antispasmodic
