Ultrasonography of normal , cystic and dysplastic kidney in cattle

Abstract

Thirty four apparently healthy cattle (9 males and 25 females) of mixed breed (Balady X Friesen) were selected for ultrasonographic investigations in this study. Ultrasonographic measurements of vertical and horizontal diameters of kidney, the diameters of the renal parenchyma and the diameter of renal sinus were determined in the middle of right and left kidneys. Twenty nine cattle (9 males and 20 females), had normal ultrasonographic appearance of both right and left kidney while the other five cows had some pathological affections including cystic kidney and renal dysplasia in their left kidneys . The vertical diameter of the right kidney was (4.84±1.18 cm) , the horizontal diameter (9.16 ± 1.35 cm) , and the vertical diameter of the renal sinus was ( 3.54 ± 1.02 cm ) . The thickness of the renal cortex and medulla ( renal parenchyma) was (2.16 ± 0.46 cm ). On the other hand ,the vertical diameter of the left kidney was (5.89 ±1.13 cm), and the vertical diameter of the renal sinus was ( 3.83 ± 1.12 cm ). The thickness of the renal cortex and medulla (renal parenchyma) was (2.46 ± 0.35 cm ). It was concluded that the ultrasonographic values determined in this study can be used as references for the diagnosis of morphologic changes in the kidney of domestic dairy cattle
