What is this Techique?

[saishu]

I think your sensei is pulling your leg. Possibly there is a technique that could make you lose control of yourself (I don't know it though myself), but "pee to death"? Nope...

LOL, I dont know but it would explain some bunkai for the openhanded palm up gedan barai's in the Hakutsuru kata.

I believe that there are techniques that most of us do not even know exist no matter how long we have studied...but...maybe the guy that got the technique applied to simply got a shot in the groin real hard, lost control of his bladder and had to be rushed to the hospital for another reason related to the strike. It seems pretty irresponsible for someone to have this technique used on another individual in a dojo setting...I mean it does not seem likely that it was an "accident." Based on this alone I think that the technique is questionable.
