Transjugular renal biopsy. Update on hepato-renal needlework.

In 1990, a poster presented at the American Society of Nephrology kindled curiosity [1]. The placard indicated that renal biopsy can be performed by puncturing the right kidney from inside, with a needle inserted along a catheter running from the jugular vein into the lower pole. Publications followed, from those who had broken new ground and thereafter from many members of the nephrological circles. Most confirmed the interest in the jugular route, others brought grist to the mill, yet others were definitely misleading regarding the technique, its indications and its complications. It is therefore time to review the issue of transjugular renal biopsy (TJRB) in the light of acquired experience and to formulate recommendations and caveats.
