Establishment of renal size parameters and renal blood flow parameters of healthy SD rats

Objective To establish the renal size parameters and renal artery blood flow parameters of healthy SD rats.Methods With high frequency color Doppler instrument,we measured the size of renal,the diameter of renal artery,blood flow parameters of main renal artery(MRA) and section renal artery(SRA).The blood flow parameters measured includes maxium blood flow velocity(Vmax),minimum blood flow velocity(Vmin),mean blood flow velocity(Vm),resistance index(RI),and pulsatility index(PI).Results No statistically significant differences was found between the size of the left renal and the right renal(P0.05).The diameter and blood flow parameters(Vmax,Vmin,Vm,RI and PI) of MRA and SRA showed no significant difference between the left and the right renal artery(P0.05).Conclusion High frequency color Doppler instrument could be used to display Rats' renal and renal artery quite clearly,and serves as the preferred choice for examination.
