  • Descrição: Our medical team conducted the percutaneous renal biopsy, using an aspirating biopsy needle (Vacu-Cut) in 101 cases, and an automatic biopsy needle (Biopty-Cut) in 82 cases. Thereafter, we examined the usefulness of the two types of needles in comparison with that of Tru-Cut used in 101 cases. The test confirmed that in the cases of Vacu-Cut, 7.6 glomeruli (p <0.01), on the average, existed in LM specimen; 9.0 glomeruli (ns), Biopty-Cut, and 10.7 glomeruli, Tru-Cut, respectively. However the incidence of cases containing more than 5 glomeruli was not significant statiscally between Vacu-Cut/Biopty-Cut and Tru-Cut. The incidence that each type of needles obtained more than one glomerulus in IF specimen was as follows: 73.3%, Vacu-Cut (p<0.05), 81.7%, Biopty-Cut (ns), 87.1%, Tru-Cut, respectively. As for in EM specimen, 61.4%, Vacu-Cut (ns), 67.1%, Biopty-Cut (ns), and 70.3%, Tru-Cut, respectively. As for complications, in the cases of Vacu-Cut and Biopty-Cut, gross hematuria and post-biopsy pain occured in 6.9 to 9.8% (p<0.01-p<0.05), whereas in Tru-Cut, they occured in 20.7 to 24.8%. As for blood pressure lowering (less than 90 mmHg) and anemia (the cases in which blood transfusion was required), 0%, Vacu-Cut and Biopty-Cut, 2 to 3%, Tru-Cut, respectively. As for fever, Vacu-Cut 0%, Vacu-Cut (p<0.01), 3.7%, Biopty-Cut (ns), and 7.9%, Tru-Cut, respectively. The above findings lead to conclusion that both Vacu-Cut and Biopty-Cut are useful instruments for renal biopsy.
