A proposed new classification for the renal collecting system of cattle.

Objective: To evaluate the intrarenal anatomy of kidneys obtained from cattle and to propose a new classification for the renal collecting system of cattle.

Sample Population: 37 kidneys from 20 adult male mixed-breed cattle.

Procedures: Intrarenal anatomy was evaluated by the use of 3-D endocasts made of the kidneys.

The bovine kidney as an experimental model in urology: external gross anatomy.

The objective of this work was to obtain and record detailed and accurate measurements of the bovine kidney and to compare these new data with findings in humans. Thirty-eight bovine kidneys were used. The total number of lobes, along with the number of lobes located in the cranial polar, caudal polar and hilar regions, were recorded.
