To establish the ultrasonographic appearance and the biometric data of the ovine kidney, B-mode ultrasonography was carried out on one ram in vivo and on 20 ovine kidneys in vitro. The echogenic pattern of the various regions of the ovine kidney was described in both vivo and vitro.
Statistical analysis of the given data showed no difference between the zonal cortical and medullary measurements, when the kidney was sagittaly scanned, while there was a significant difference between the sagittal and transverse medullary measurements. The weight and volume of the kidney were correlated (r= 0.93). No correlation was found between the kidney volume and any of the other measured perameters.
