Emptying Catheter Drainage Bag

Key Points

  • Keep drainage spout from touching measuring container surfaces.
  • Disinfect drainage spout and holder after emptying.
  • Measure output at eye level and document volume and urine characteristics.
  • Perform hand hygiene before any bag or connector manipulation.

Equipment

  • Gloves
  • Two barriers
  • Graduated cylinder
  • Alcohol swabs

Procedure Steps

  1. Complete routine pre-procedure actions and don gloves.
  2. Place floor barrier under drainage bag and set graduated cylinder on barrier.
  3. Open drainage port and allow urine to flow into cylinder without touching port tip to cylinder.
  4. Close drain and disinfect drain tip with alcohol swab.
  5. Disinfect drain holder (if present) and replace drain in holder.
  6. Place clean barrier on flat surface and place cylinder on barrier.
  7. Read urine output at eye level in mL.
  8. Assess urine characteristics: color, clarity, sediment, and odor.
  9. Escalate urgent abnormalities such as gross hematuria with clot burden, sudden drop in output, or new severe suprapubic discomfort.
  10. Empty urine into toilet; rinse cylinder and empty rinse water into toilet.
  11. If switching between day and night drainage bags, clean connector junction with soap and water and allow to dry before reconnection.
  12. Store equipment, remove gloves, perform hand hygiene, and complete post-procedure safety checks.
  13. Document urinary output and report abnormal findings.

Common Errors

  • Allowing drain tip contact with cylinder increases contamination risk.
  • Skipping alcohol disinfection of spout/holder increases infection risk.
  • Reading output off eye level causes inaccurate urine balance documentation.
  • Reconnecting bags without cleaning and drying the connector increases CAUTI risk.
