Usefulness of Adjustable Needle Sizes for Biopsies YouTube

E. David Crawford, MD, Professor of Urology at the University of California, San Diego, discusses the usefulness of adjustable needle sizes for prostate biopsies with Jelle Barentsz, MD, PhD, Professor of Radiology at the Nijmegen Medical Center of Radboud University in Nijmegen, The Netherlands. Dr. Barentsz agrees with Dr. Crawford that a needle that can be adjusted from 10 to 60 gauge would be useful in situations such as when the smaller needle sometimes needed to reach an area is unable to pierce through fat to take the needed core sample. Drs. Barentsz and Crawford then address the pros and cons of mapping biopsy of the prostate: Dr. Barentsz contends that the use of 180 needles to obtain only slightly more accurate results than MRI may not be warranted, and Dr. Crawford notes that mapping biopsies are usually reserved for patients with negative MRIs and negative biopsies.
