What is the minimum routine flushing volume for adults?

• A. 10 mL
• B. 30 mL
• C. 60 mL
• D. 5 mL

Answer: (B)

Flushing aims to clear the stoma and the pouch so waste is evacuated and the appliance stays clean. The minimum amount of water that reliably achieves this in adults is 30 mL. This volume provides enough flow to push stool through the stoma and out of the pouch; smaller amounts are unlikely to move thicker stool or fully empty the lumen, increasing the risk of blockage or leakage. Larger volumes, such as 60 mL, may be used in specific situations or with larger stomas but aren’t the minimum. Very small amounts like 5 or 10 mL won’t adequately evacuate contents and aren’t recommended for routine flushing.
