Abstract
PURPOSE: To compare the coaxial and noncoaxial techniques of renal parenchymal core needle biopsy. MATERIALS AND METHODS: This is an institutional review board-approved randomised controlled trial comparing 83 patients (male, n = 49) who underwent renal parenchymal core biopsy with coaxial method and 83 patients (male, n = 40) with noncoaxial method. The rate of complications, the number of glomerular profiles, and the procedural time were evaluated in a comparison of the two methods. Correlation between the presence of renal parenchymal disease and the rate of complication was also evaluated. RESULTS: The procedural time was significantly shorter in the coaxial technique (coaxial group, 5 ± 1 min; noncoaxial group, 14 ± 2 min; p < 0.001). The rates of complications for the coaxial method was significantly lower than the noncoaxial method (coaxial group, 10.8 %; noncoaxial group, 24.1 %; p = 0.025). There was no significant correlation between gender and the rate of complication. The number of glomerular profiles was significantly higher in patents who underwent renal biopsy with the coaxial method (coaxial group, 18.2 ± 9.1; noncoaxial group, 8.6 ± 5.5; p < 0.001). In the whole study population, the rate of complications was significantly higher in patients with a pathologic renal parenchyma compared to those with a normal parenchyma (19/71 vs. 10/95; p = 0.006). CONCLUSIONS: Renal parenchymal biopsy using a coaxial needle is a faster and safer method with a lower rate of complications.
