Catheter during surgery?

A few weeks ago I had surgery on my cut tendons and nerve in my wrist. It was a 4 hour procedure, however I was aloud to keep my underwear and PJ shorts on during it. However I was wondering if they inserted and removed a foley catheter when I was asleep? I didn't have one inserted when I went to theater and then I didn't wake up with one. However after the 4 hour surgery I was then in the recovery room for 6 hours, before going back to the ward and having a wee.
