Abstract:
PURPOSE: To compare the efficacy of 14 gauge(G) Vim-Silverman needle biopsy with that of 16G automatic gunbiopsy for kidneys and to determine the optimal needle size for renal biopsy. MATERIALS AND METHODS: Weretrospectively reviewed the pathologic and medical records of 119 (110 native, 9 allograft) patients who hadundergone 14G Vim-Silverman needle biopsy and 71 (34 native, 37 allograft) who had undergone 16G automatic gunbiopsy. The number of retrieved glomeruli and post-biopsy complications were compared between the two groups. Exvivo renal biopsies of a dog were performed using an automatic gun mounted with 14G-20G needles and the numbers ofretrieved glomeruli were compared. RESULTS: The number (mean+/-standard deviation) of retrieved glomeruli perbiopsy in native/allograft/total kidneys was 32.1+/-20.9/24.0+/-15.2/31.5+/-20.6 in the 14G Vim-Silverman needlebiopsy group, and 26.9+/-16.2/14.3+/-10.1/20.9+/-14.9 in the 16G automatic gun biopsy group. In the dog, the numberof retrieved glomeruli per biopsy was 17.2+/-6.3/9.2+/-3.9/5.7+/-4.5/3.9+/-2.6 in the 14G/16G/18G/20G groups,respectively. CONCLUSION: Although significantly more glomeruli were retrieved in the 14G Vim-Silverman needlebiopsy group, the number retrieved in the 16G automatic gun biopsy group was sufficient for adequate pathologicinterpretation. Experimental study suggests that when an 18G automatic gun is used, sufficient glomeruli areretrieved.
