Is a catheter nessesary during labor if you get an epidural or other pain releif?do you have to get one?

No: However you have to have a nurse that will be watching and emptying your bladder routinely.

Not usually: It is not standard of practice in our area unless you end up in surgery maybe. Certainly not for vaginal deliveries!

No: You do not "need" one, but with an epidural, or other forms of pain relief, you may not have the urge to void, thus, your bladder needs to be emptied either way. Typically, for good or bad, laboring patients are given lots of fluid during labor, exacerbating the problem.
