Safe Foley Catheter Balloon Deflation: Step-by-Step Clinical Procedure

Indications

Deflation is performed for catheter removal, routine exchange, or troubleshooting. Only trained personnel should perform this procedure using aseptic technique.

Equipment

• 10 mL or 20 mL Luer-lock syringe (size matches balloon volume—check catheter labeling)
• Sterile saline or water (for accidental over-deflation)
• Clean gloves
• Antiseptic wipes
• Collection container for urine
• Sharps container

Procedure

1. Hand hygiene and don clean gloves.
2. Identify the inflation/deflation valve—typically a color-coded port near the catheter hub. Confirm balloon volume printed on catheter (usually 5, 10, or 30 mL).
3. Attach syringe securely to the valve.
4. Aspirate gently by pulling back the plunger. The balloon should deflate smoothly. Do not force aspiration—resistance may indicate valve malfunction, debris, or balloon herniation.
5. Confirm complete deflation by aspirating the full rated volume. If unable to aspirate expected volume, do not pull catheter; seek urology consultation.
6. Detach syringe and dispose in sharps container.
7. Remove catheter by gentle, steady traction. If resistance encountered, stop and reassess.
8. Inspect catheter for balloon integrity and document.
9. Monitor patient for voiding, discomfort, or bleeding post-removal.

Troubleshooting

• Valve won't aspirate: Try repositioning patient, gentle catheter milking, or instilling 1–2 mL saline to clear debris. Never cut the inflation arm.
• Balloon rupture suspected: If fragments remain, cystoscopic retrieval may be needed.
• Patient discomfort: Pause, reassure, consider topical lidocaine jelly.
