I am looking for advice on how to refinish a couple of interior doors. I think
they were stained and then topcoated with a semi gloss polyurethane.
They are basically really dirty. Should I / could I strip and restain? Or
could I get away with sanding and recoating with polyurethane ?
Yes...I hope so:
I'm dealing with a similar situation and am using a matching shade of
Minwax Polyblend to feather into the existing (once the degraded finish
is cleaned up) then topcoating with their Spar Urethane.
A few days will tell.

If it's just the poly that is really dirty then you shouldn't need to sand
at all. The poly should clean up with anything up to and including paint
thinner. The obvious caution is that you would want to apply paint thinner
on a dampened rag and not a lot of it, so you don't soften the poly.
What kind of "dirty" are you talking about here? If the existing poly was
put on right, then just about anything you'd typically find in a household
environment will usually just be a dirt or grime layer on top of the poly -
no need to sand. If it were not put on right and did not seal the surface
well so that the grime actually penetrated into the wood, then sanding will
likely be in order as will matching the stain or posibbly even restaining
the whole door, then applying new poly. Do try to get whatever it is off
though since no stain is going to hide what's beneath it. You'll see
blotching and differing depth of stain penetration/color where the grime is
if you don't get all of the grime off.
Have often read that poly doesn't like to stick to anything including
itself so sanding between coats is a given. A wipedown with naptha to
remove dirt/grime then scuff sand then recoat would be my preference.
