Problem: Urine backflow. Solution: Keep the drainage bag below the level of the bladder so urine will flow downward through gravity.

Problem: The catheter is being pulled or tugged. Solution: Keep the tubing secured to the upper thigh at all times to reduce tension on the catheter. Catheter straps are often used to secure extension tubing in place.

Problem: Urine is not draining into the leg bag or urine collection device. Solution: Regularly empty the leg bag or collection device, always leaving a small amount of urine in the bag to avoid creating a vacuum. When a vacuum is created, it prevents urine from draining into the bag or collection unit.

It’s important to contact your healthcare professional directly if you are experiencing issues with your male external catheter such as swelling, rash, pain or extreme discomfort.
