Hi, This week I had a perineal prostate biopsy and now waiting for the pathology report.
This is a curiosity question - I had 14 needles and 24 core samples taken. Some needles were for 1, 2 or 3 samples. Does anyone know how this works? Do they have a way of using the one needle to sample at various depths / locations within the prostate?

Don't know about various depths but, yes, the needle is normally presented transrectally to the hardest or lumpy part of the prostate. This area of the prostate is determined by a previous DRE (e.g. right side) and is the one most likely to render a positive result if cancer is present. The administering Physician determines the course of the probe by referring to an ultrasound screen during the process.

Never heard of this. A sample usually means 1 needle core.
