I sort cabinet, tidying it up for medical specialist (12)

I believe the answer is:

obstetrician

I'm a little stuck... Click here to teach me more about this clue!

'for medical specialist' is the definition.
(obstetrician is a kind of medical specialist)

'i sort cabinet tidying' is the wordplay.
'tidying' is an anagram indicator.
'i'+'sort'+'cabinet'='isortcabinet'
'isortcabinet' anagrammed gives 'OBSTETRICIAN'.

'it up' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.

Can you help me to learn more?

(Other definitions for obstetrician that I've seen before include "specialist" , "Childbirth doctor" , "Labour supporter" .)

I've seen this clue in The Irish Times.
