Enema before transperineal biopsy?

I've read quite a few threads hear containing talk about an enema before their biopsy, but I have had no instructions to do that. I know that the patients having a transrectal probably should and were probably specifically instructed to do so.

Gotta say, if it's not 'required', I'm not going to do it. I've checked all the preop instructions, THREE times, and it's not mentioned.

Anyone NOT instructed to do an enema before a transperineal biopsy?

Biopsy scheduled for Monday morning. The anxiety has been overwhelming!

Thanks!
