Basically, the penis fish (not its ACTUAL name) is a tiny fish that exists down in South Amreica with VERY strong scales that are designed to flatten out when pushed one way, but lock solid when pulled the other.
The practical effect of which is that they can accidentally swim UP the penis when you are swimming in the river, but can't come out of it again without tearing out the inside lining.

It swims up the urethra. So the operation is not that complex. Its cut at the base of the member and the fish taken out. Not to damaging.......the operation I mean.
