Doctor’s glorious, operating on ureters essentially (9)

I believe the answer is:

urologist

'doctor's' is the definition.
(urologist is a kind of doctor)

'glorious operating on ureters essentially' is the wordplay.
'operating' indicates an anagram.
'on' says to put letters next to each other.
'essentially' says to take the centre.
The middle letter of 'ureters' is 't'.
'glorious' is an anagram of 'urologis'.
'urologis'+'t'='UROLOGIST'

(Another definition for urologist that I've seen is " Doctor specialising in the waterworks?".)

I've seen this clue in The Hindu.
