A novel 19-gauge, blunt-tipped, side cutting single throw, 70-cm long transjugular needle, specifically designed for transvenous kidney biopsy, was used in seven patients with high risk for bleeding. A mean of 4 device-passes (3–6) per patient resulted in a satisfactory specimen for pathological diagnosis. Immediate post-biopsy nonenhanced CT was performed to evaluate for bleeding at the biopsy site. All patients were observed for 2 hr after the procedure. No clinically significant immediate or late complication was noted.
