Ultrasound-guided prostatic biopsy using biplanar transrectal probe. Our experience

In the last three years we performed more than 200 echo-guided prostatic biopsies using different probes. Recently, thanks to the availability of a bi-planar transrectal probe we have developed a technique that resulted simple rapid well accepted by the patients and above all able to center small prostatic nodules. We have studied with this technique 96 patients performing 120 biopsies. For the biopsy we used a 19 G cutting-needle introduced under local anaesthesia parallel to the probe (linear array) when the needle is on the target we turn on the axial view and we check the position with respect to the center of the lesion, then, returning to the sagittal view we perform 1 to 3 biopsies for microhistological and cytological examination. With this method we have reached a better accuracy of diagnosis.
