Comparative Study of Efficacy on Percutaneous Renal Biopsy Guided by Ultrasound with Two Approaches / 中国医师杂志

ABSTRACT

Objective To investigate the efficacy of percutaneous automatic renal biopsy guided by ultrasound with two approaches. Methods One hundred and fifty patients who were suspected with diffuse renal disease were divided into two groups randomly: group A (n=74) and group B (n=76). In both groups A and B, an 18G cut needle with automatic biopsy gun was inserted the inferior pole of right kidney from proximal and distal end of transducer, respectively. After accomplishment, the times of puncture, length of sample, number of glomeruli and complications were recorded were recorded. And the number of glomeruli per centimeter was calculated. Results The differentiation of diffuse renal disease was assured by the specimens obtained by biopsy in all the patients. The puncture times in group A was less than those in group B (P0.05), and the number of glomeruli per centimeter in group A was more than that in group B (P
