What is it about?
We looked at 242 patients who had undergone needle biopsy of the kidney with the help of ultrasound. We confirmed something that had probably been known for many years: that aiming the needle at the upper or lower ends of the kidney is safer as it avoids the big blood vessels but it also provides a better specimen. We also uncovered another important, seemingly minor detail: angling the needle at between 50 to 70° to the surface of the kidney also yielded the safest results, and the best specimens to allow the pathologist to have the best chance possible to clinch a diagnosis.

Why is it important?
These may seem like minor details, but our study suggests that paying attention to these minor details will lead to safer outcomes and better biopsies for our patients undergoing needle kidney biopsies.
