Abstract:
Objective:To compare the injury of renal blood vessels using different puncture pathways and access sizes.Methods:Between April 2018 and June 2019, eighty fresh pig kidneys were selected to perform percutaneous puncture and dilation, which was used to compare the injury of renal blood vessels with different puncture pathways and access sizes. The puncture pathway included the centerline of the normal renal pyramid (A), centreline of one side pyramid of the fused renal pyramid (FRP) (B), midline of the entire FRP (C) and midline of the renal column (D). The access size included F8, F12, F16, F20, F24 and F30. Histopathological methods were used to analyze the injury of renal blood vessels.Results:The puncture through paths A and B mainly caused injury to the grade Ⅴ and Ⅵ arteries in renal cortex. The puncture often directly injures the grade Ⅳ artery in path C. The puncture often simultaneously injures the grade Ⅲ-Ⅵ arteries in path D. Grade Ⅲ artery injury began to occur when paths A, B, C, and D were dilated to F30, F24, F16, and F12, respectively. The degree of arterial injury among the four different puncture pathways was significantly different in F8, F12, F16, F20, F24 and F30 ( P<0.05). Statistical differences were found between paths A and D in F12, F16, F20, F24 and F30 ( P<0.05), and between paths A and C in F16, F20 and F24 ( P<0.05). No significant difference was found between paths A and B in all access sizes ( P>0.05). Compared with F8, the degree of arterial injury of the F30 in path A and the F24 and F30 in path B were increased significantly ( P<0.05). Conclusions:Vascular injury in path D was the most serious followed by that in path C. Relatively little vascular injury can be achieved in paths A and B. The vascular injury increased when the path B was dilated to F24, while the path A needed to be dilated to F30.
