Résumé
Didelphis aurita is a marsupial with wide distribution in the South American continent and highly adapted to urban centres. The objective of this study was to describe the measurements and skeletopy of the kidneys and renal vascularisation of this species. With this aim, 29 cadavers (14 males and 15 females) of D. aurita collected on highways were analysed. The rostrum-sacral length of specimens, kidney measurements (length, width and thickness) and the length of the renal vessels were measured and the renal skeletopy registered. In the right kidney, average length, width, thickness and ellipsoid volume were 28.6 ± 5.0 mm, 15.6 ± 2.9 mm, 12.8 ± 3.0 mm and 3.3 ± 2.4 cm3, respectively; in the left kidney, 31.0 ± 3.8 mm, 14.5 ± 3.6 mm, 12.6 ± 2.6 mm and 3.2 ± 2.2 cm3, respectively. There was no significant difference in the comparison of averages of renal dimensions between sexes and between antimeres. The right renal artery (13.2 ± 2.6 mm) was significantly longer (p < 0.01) than the left renal artery (10.7 ± 2.3 mm). In contrast, the left renal vein (13.9 ± 3.5 mm) was longer (p < 0.01) than the right renal vein (7.0 ± 2.3 mm). The skeletopy of the right kidney predominated between T13-L1 in 58.6% of the cases and the skeletopy of the left kidney between L1-L3 in 41.4%. The average length of the kidneys corresponded to 6% to 8% of the rostrum-sacral length of the specimens. The data of the present study characterised the measurements and topography of kidneys and renal vessels in D. aurita and can support the interpretation of clinical, experimental and pathological findings in this species.

BACKGROUND
Didelphis aurita is a marsupial with wide distribution in the South American continent and highly adapted to urban centres. The objective of this study was to describe the measurements and skeletopy of the kidneys and renal vascularisation of this species.
MATERIALS AND METHODS
METHODS
With this aim, 29 cadavers (14 males and 15 females) of D. aurita collected on highways were analysed. The rostrum-sacral length of specimens, kidney measurements (length, width and thickness) and the length of the renal vessels were measured and the renal skeletopy registered.
RESULTS
RESULTS
In the right kidney, average length, width, thickness and ellipsoid volume were 28.6 ± 5.0 mm, 15.6 ± 2.9 mm, 12.8 ± 3.0 mm and 3.3 ± 2.4 cm3, respectively; in the left kidney, 31.0 ± 3.8 mm, 14.5 ± 3.6 mm, 12.6 ± 2.6 mm and 3.2 ± 2.2 cm3, respectively. There was no significant difference in the comparison of averages of renal dimensions between sexes and between antimeres. The right renal artery (13.2 ± 2.6 mm) was significantly longer (p < 0.01) than the left renal artery (10.7 ± 2.3 mm). In contrast, the left renal vein (13.9 ± 3.5 mm) was longer (p < 0.01) than the right renal vein (7.0 ± 2.3 mm). The skeletopy of the right kidney predominated between T13-L1 in 58.6% of the cases and the skeletopy of the left kidney between L1-L3 in 41.4%. The average length of the kidneys corresponded to 6% to 8% of the rostrum-sacral length of the specimens.

CONCLUSIONS
The data of the present study characterised the measurements and topography of kidneys and renal vessels in D. aurita and can support the interpretation of clinical, experimental and pathological findings in this species.
