Ultrasonographic evaluations performed. (A) B mode sonographic sagittal view of the left kidney of a bitch delimited by the electronic callipers, measuring the length and height. (B) B mode sonographic transverse view of the left kidney of a bitch at the level of the renal hilum to measure the transverse height. (C) Color Doppler sonographic image of the renal artery (delimitated by the circle calliper) to obtain the vessel area. (D) Pulsed-wave Doppler of the renal artery to obtain the spectral tracing and Doppler flowmetry indices.
