Different from renal artery only clamping, artery and vein clamping causes a significant reduction in number of rat glomeruli during warm ischemia.

Purpose: To evaluate glomerular injury in the rat model during renal warm ischemia (WI), comparing artery and vein (AV) clamping with artery only (AO) clamping.

Materials And Methods: Twenty-four adult male rats underwent 60 minutes of renal WI in the left kidney. The animals were divided into three groups: AV clamping, AO clamping, and Sham surgery.

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.

Pig kidney: anatomical relationships between the renal venous arrangement and the kidney collecting system.

Purpose: We present a systematic study of the anatomical relationship between the intrarenal veins and the kidney collecting system in pigs.

Materials And Methods: The intrarenal anatomy (collecting system and veins) was studied in 61, 3-dimensional endocasts of the kidney collecting system together with the intrarenal veins.

Results: There are free anastomoses between the intrarenal veins.
