Abstract: Objective To investigate the arterial injury in vitro porcine kidney to different size of nephrostomy tracts. Methods The technique of percutaneous nephrostomy was applied to establish 11 groups of different size of nephrostomy tracts from 12 F to 32 F,with 40 tracts in every group.The technique of digital subtraction angiography (DSA) was used to inspect and analyze arterial injury. Results In the range from 12 F to 32 F,the damage of arterial injury increased with the size of the tract diameter.In groups of 20 F and 32 F,the number of nephrostomy tracts with serious arterial injury was 18 (18/40) and 30 (30/40) respectively,and the difference was statistically significant (P＜0.05).There was no statistical difference between groups 18 F、20 F、and 22 F. Conclusions The damage of renal arterial injury increased with the size of the nephrostomy tract.Atract of 20 F reduees arterial injury compared with a tract of 32 F.
