ABSTRACT
PURPOSE:
Assess glomerular yield and safety profile of two different types of needles for percutaneous ultrasound-guided kidney biopsy. MATERIALS ANDMETHODS:
Over 24 months, 121 ultrasonographic ultrasound-guided renal biopsies were performed on native kidneys of 121 adults 66 with 16-gauge, 29-mm end-cut (BioPince) needles and 55 with 14-gauge, 1.9-mm side-notch (Tru-Cut) needles.RESULTS:
The mean number of complete glomeruli harvested per biopsy was 21.0 and 19.3, respectively, and the mean number of core samples required to obtain a satisfactory biopsy was 1.8 and 2.6, respectively. The ratio of glomeruli harvested to core samples needed with the end-cut needle was 58% greater than that with the side-notch needles (11.7 vs 7.4, respectively; difference of 4.3; 95% confidence interval 2.0, 6.8). Procedures performed with end-cut needles were associated with fewer major complications (1.5% vs 7.3% with side-notch needles).CONCLUSIONS:
Compared to the 14-g Tru-cut needle, the 16-g end-cut needle provided better glomerular yield per core sample, required fewer cores for satisfactory tissue specimen, and resulted in fewer major complications.
