Another update.
Dr Chet's liaison official, Som, says that he prefers to perform an orchiectomy under general as 'the surgery can be very painful and uncomfortable.' Mr Som is also pushing quite hard about the referral letters, mentioning that they must be originals with original handwritten signatures. This is fine of course.
Meanwhile, Dr Somboon at Bangkok Hospital is happy to do it and his clinic writes: 'it is a very simple procedure. Normally, we do under local anesthesia as an out-patient procedure.' They mention one psychiatric referral letter.
So there we have two contrasting views about the nature of orchiectomies. My surmise is that the SRS surgeons don't perform many standalone orchiectomies and are used to major invasive surgery under general anaesthetic which costs a lot of money. That's their
metier and I don't think they perform many orchiectomies. The urologists and non-SRS specialists, and indeed vetinarians (!), know it's a relatively simple, non-invasive, procedure that can be done under local, and they perform it fairly regularly. Remind me of this comment when I'm howling with pain
