Hands off the catheter, my friend

I had a patient remove his own foley catheter the other day and it was not a pretty site. It's unclear whether said extraction was intentional or not but the result was a positively bloody mess. As you'll see from the diagram below, the catheter is maintained in place in the bladder via an inflated balloon, so just imagine the damage that can be done when that balloon passes through the urethra and out of the penis without FIRST being deflated.

yowee!
