Transrectal Biopsy

Ultrasound (US)-guided biopsy is now the standard of care. A transrectal approach is used for most prostate biopsies, although some urologists prefer a transperineal approach. Usually the procedure is performed under local anesthetic. A needle is attached to a biopsy gun and mounted on a ultrasound probe and inserted through the rectal wall into the prostate to acquire biopsy cores under the guidance of US images

12 biopsy cores are 'randomly but systematically' acquired from different zones of the prostate without a patient-specific plan (i.e. without regard to specific location of the abnormalities)

  • Limitations of systematic biopsy technique
    • False-Negative Biopsy (under sampling)
    • Incorrect Risk Stratification (under sampling)
    • Detection of Clinically Insignificant Disease (over sampling)
    • Necessity of Repeat Biopsy (reduction of sampling error by increasing sampling)

Fusion transrectal biopsy with BiopSeeĀ®

Using BiopSeeĀ® the transrectal biopsy is not anymore blind, since the suspicious lesions noted by the radiologist in the MRI of the prostate, can be overlaid with the live ultrasound image to target the needle in the suspicious area of the prostate.
