But journalism should offer both sides of a story for balance
The story is former patient in legal challenge against medical centre that treated her.
Such a story first reports on who is the patient and what does she allege has gone wrong. Balance is provided by giving the medical centre the chance to reply to the allegations.
That would have been unbiased, at least on the surface (you can easily manipulate the audience response by how much airtime you give to each side, how you describe both sides and who gets the last word).
Seeking to undermine this former patient's allegations by featuring - however briefly - the story of a much younger patient currently being treated, whose case is not connected to the former patient's one in any way and which may not even be connected to the clinic in question (we are not told) upends this balance.
One could restore the balance by for instance referencing a medical expert who prefers a different treatment approach explaining how this might have avoided the harm this former patient suffered. (This would have been pertinent information to the audience in any case, who are not told that there is a second treatment approach considered to be best practice internationally, backed up by empirical evidence not available for the treatment approach used for this former patient.)
It is not entirely unwarranted to provide such additional details as the audience might need to understand the case, but it should be finely balanced.
A claim of "However, most gender reassignment stories are positive." without providing statistical evidence is neither good journalism nor balance, but emotional manipulation of the audience instead.
