Percutaneus renal biopsy using Biopty biopsy instrument and Biopty biopsy needle

We assessed the clinical usefullness of Biopty biopsy instrument & Bioty biopsy needle in percutaneus renal biopsy (PRB) compared with Tru-cut disposable needle and Vim-Silvermann needle. Sixty cases, each consisting 20 cases, were performed PRB by 3 different needles. There was no significant differences between Biopt y-cut needle and Tru-cut needle in the length of renal biopsy tissue and number of glomeruli obtained. The frequency of clinical complications such as fever, flank pain and decrease in Ht>2% was lower in Biopty needle group after PRB. The frequency of middle and large size of hematoma was also lower in Biopty needle group after PRB. We could also obtain specimen from transplated kidney without complications except small hematoma. From-three results, Biopty biopsy needle is a useful tool in performing PRB.
