"It was a transgender patient who had surgery at a different clinic to remove male genitalia – and had since changed their mind "
"It" - singular
"a transgender patient" - singular.
"their" - plural
"mind" - singular. (Unless the writer is, perhaps, trying to imply multiple entities with a 'collective' mind.)

More like the natural consequence of severe mental conflict.
In fairness, when you are talking about a person who was one sex then changed to another and now identifies as their original sex, and you are required to now pretend people are whatever they say they are regardless of biology, it can get a bit dicey to choose pronouns without sparking a boycott.
I had my yearly physical just this evening. I was “asked” to circle which pronouns I use...
