When a Blocked Catheter Becomes a Flood Warning There's an old saying that you don't miss the plumbing until it stops working. Anyone who has cared for a spinally injured person knows just how true that is. A blocked catheter isn't just an inconvenience. It can quickly become a genuine medical emergency. This cartoon imagines an A&E department slowly disappearing beneath a rising tide while one member of staff shrugs, "Well, at least he's bypassing." 

It's absurd, of course... but like most satire, it contains a grain of uncomfortable truth. For anyone unfamiliar with the term, bypassing is when urine can't drain through the catheter because it's blocked, so it escapes around the outside of the catheter instead. To the untrained eye, that might look like the bladder is emptying itself. In reality, it can be a warning sign that pressure is building inside the bladder. For someone with a high spinal cord injury, that pressure can trigger Autonomic Dysreflexia (AD)—a sudden and dangerous spike in blood pressure that can lead to stroke, seizures or worse if the underlying cause isn't treated promptly. 

The frustrating part is that blocked catheters are rarely mysterious. Experienced spinal injury carers spot the warning signs early: Little or no urine draining into the bag. Increasing bypassing. Abdominal discomfort or bladder distension. Sweating, flushing or a pounding headache in someone with a spinal cord injury. The solution isn't to mop up the bypassing and hope for the best. It's to recognise that the catheter may no longer be doing the very job it was inserted to do. Humour allows us to laugh at the ridiculous, but it also shines a light on the serious gaps in knowledge that still exist outside specialist spinal units. 

Too many carers, nurses and healthcare professionals receive little or no spinal injury training before finding themselves responsible for someone whose condition can deteriorate rapidly. That's exactly why we created Fellow Carer. Our spinal injury training is designed for individual carers, home care agencies and healthcare organisations, giving staff the confidence to recognise problems early and respond appropriately—before a small blockage becomes a very big emergency.  

Have you ever experienced a blocked catheter that wasn't recognised quickly enough? What do you think healthcare providers could do to improve awareness of spinal injury emergencies? We'd love to hear your experiences in the comments.
