Over the past years the approach to kidney biopsy has evolved using ultrasound techniques during and before the procedure to assess the correct positioning of the automatic needle for the kidney biopsy. Adverse events might be possible, but rarely are severe. Nowadays, for this reason, ultrasound-guided kidney biopsy is the gold standard to collect kidney specimens for histopathological analysis.
