? Crede' of the Bladder

I recently went out to a home vent case and the plan of treatment included a procedure that I have never heard of and I would like to know if any of you have experience with this.

It was explained to me that if I push manually on the bladder area that it will expell urine. This patient is semicomatose, & experiences no pain during this procedure. She is place on the bedapin then the crede procedure. I have tries to search this on line and can't find any information on this procedure.

Please reply if you know anything related to this.

Thank you,
