Renal needle biopsy along the retrograde puncture line of the renal calyx: a new promising technique.
The Biopty-gun is a useful tool in conducting percutaneous renal biopsies, but bleeding is still a significant complication. To reduce the rate of severe bleeding complications, we attempted a new method of renal needle biopsy using a retrograde access technique. Retrograde puncture of the renal calyx was performed using the Lawson nephrostomy kit. The 18-gauge needle of the Bioptygun was inserted along the puncture wire and fired. A 7-french pigtail catheter was retained in the renal pelvis for a few days following the procedure. This biopsy is a promising and safe technique.
