Intrarenal anatomy was studied in detail to evaluate how useful rabbits could be as a urologic model. Only one renal artery was observed, which was divided into dorsal and ventral branches in all cases. Three segmental arteries (cranial, mesorenal and caudal) was the most frequent branching pattern found in both the dorsal and ventral division. There was an important artery related to the ureteropelvic junction in both dorsal and ventral surfaces in all specimens. The cranial pole was supplied by both dorsal and ventral divisions of the renal artery in 23 of 41 casts (56%). Although the cranial pole of the rabbit kidney could be useful as a model because of the resemblances with human kidney, the different relationship between the intrarenal arteries and the kidney collecting system in other regions of the kidney must be taken into consideration by the urologists, when using rabbit kidney in urological research.
