Percutaneous renal biopsy is an essential component for diagnosis and management
of glomerular diseases. Recently; the use of a spring-load biopsy gun is popularized. There have
been many controversies on the tissue adequacy and the incidence of complications in automated
gun biopsy comparing to the manual biopsy. The present study was performed to compare the
tissue adequacy and the incidence of complications between manual biopsy and automated gun
biopsy. We retrospectively analyzed records of 306 patients performed manual biopsy from
January 2000 to February 2003; and of 319 patients performed automated gun biopsy from March
2003 to December 2005. In manual biopsy group; number of cores was 2.7 ± 0.56; glomeruli per
core was 9.5 ± 5.85; mean of glomerulus was 24.3 ± 13.78; and in automated gun biopsy group
2.9 ± 0.15; 9.2 ± 4.89; and 27.4 ± 14.05; respectively. These showed no significant difference
between two group. Significantly fewer hematoma complications (p<0.05) occurred in the
automated gun biosy group (15.1%) comparing to the manual biopsy group (20.9%). Ultrasoundguided
percutaneous renal biopsy using automated gun seems to be an effective method for the
pathologic diagnosis of renal diseases with lower complication incidence. |
