Quite a few on here recommend the template biopsy.
Not long ago the biopsy was done before the MRI. Now they do the MRI first so the doctor knows where to put the needles. You could say that makes the TRUS more accurate than they were.
That said, the template is, I'd feel sure, more accurate in that there are around 24 needles each positioned by a template. Whereas the TRUS method uses 12 needles 6 on each side positioned by the doctor.
In my case only 1 needle found any cancer on 5% of that needle's sample. So it was nearly a miss with a lesion of 13mm, Gleason 4+3, which seems a pretty big target to me. I hadn't had an MRI though and actually 3 of the needles had no sample for some reason. I wondered if that was because I clenched my muscles at one stage and was told to stop doing it. It's not painful but like a dull discomfort.
TRUS uses local anaesthetic and Template usually General Anaesthetic. At the end of the day they only need to find one sample on a suspected lesion. If you imagine a walnut with 12 or 24 needles being stuck in although yours is quite a big walnut.
I'd never had a General Anaesthetic and I seem to recall a reluctance to have one so I'm not sure I'd have gone for a template and if they'd said it would need a wait of a few weeks longer it would have been a factor against it.
I recall the doctor saying to me he'd rather take a few extra weeks to get a better diagnosis and I said, amicably, I'd rather he had enough information and got the whole process done as fast as he could. Some patients share his view.
The decision isn't quite so clear cut and can depend on your attitude to carrying a lesion and if you trust the TRUS. All the best Peter
