Abstract

The focus of the present study was to present a case of multilobar kidneys with smooth surface in one New Zealand white rabbit. It is well known that the kidneys of the rabbits are unipyramidal. During dissection it was found that there was an exception in one female animal which was clinically healthy and sexually matured, aged 8 months and with weight from 2.5 kg to 3.2 kg. After evisceration of both kidneys, and incision in the lateral borer of the fresh organs, it was found that the cortex and medulla were constructed by pyramidal shaped lobes. The apex of the lobes formed papillae and got up into calices into the real sinus. The renal pelvis was a concave structure. We conducted an imaging anatomical study. The anatomical preparations were studied in liquid isotonic medium, using ultrasound device with linear transducer. Thus we confirmed the results with these of the organs’ morphological features. The cortex with the fibrous capsule were hyperechoic, compared to the relatively hypoechoic image of the pyramidal lobes. The papillae forming the apex were outlined by the hyperechoic calices. The renal pelvis and hilus were hypoechoic findings. After fixation the kidneys in 10 % water solution of formalin the pyramidal shaped lobes were preserved and with well distinguished papillae. The calices protruded into the sinus. In all methods we found seven number of well-defined pyramidal shaped lobes.
