Análise comparativa entre as características morfológicas renais dos felinos domésticos (Felis catus) e grandes felídios (Puma concolor)

Abstract

The kidneys are paired structures covered externally by a capsule of dense connective tissue, resembling a bean grain shape, thin and well defined. They are located in the retroperitoneal space, located ventral to the transverse processes of the vertebrae in the dorsal abdominal wall, projecting cranially to the last ribs of the abdomen. For this research, four animals were used, two large felines (Puma concolor), and two domestic felines (Felis catus), so that both species went through the dissection process to recognize the structures and anatomical location of the organ under study. During the dissection process so far there has been a difference in kidney size, kidney weight and vein caliber. and renal arteries between species, in addition to the fact that one of the large felids had an extra renal vein on the right side, differentiating itself from other animals. However, it is noted that the topographic location of the kidneys of jaguars is similar to that of domestic felines. The aim of the study is to characterize the kidneys of domestic felines (Felis catus) and the kidneys of large felines (Puma concolor) in the macroscopic part, making it possible to carry out a comparative analysis of the renal morphological characteristics between the two species, to verify possible differences between they. The aim is also to obtain information that explains the appearance of changes that may predispose the occurrence of common pathologies in feline clinics.
