“…Previous ultrasonographical studies have reported that the normal size of the feline kidney varies between 3.0 and 4.3cm, and can even be up to 5.3cm (Walter et al, 1987, Park et al, 2008. The result obtained in Ragdoll cats (Debruyn et al, 2013) of 3.83 ± 0.45cm (range 2.98-5.09) fits well within this interval and corresponds with the renal length found by Park et al (2008) in healthy Korean domestic shorthair cats. The results of the authors above are similar to that observed in our study.…”

The aim of this study was to characterize the renal morphology and anatomical variations of the renal pedicle in domestic shorthaired cats. Dissections were performed in 40 adult cats, obtained from the necropsy unit without macroscopic renal pathology. Kidney dimensions (length, width, and thickness) and the length and origin of the renal arteries and main branches were measured. The length, width and thickness of the right kidney (cm) were 3.83±0.46, 2.42±0.22, and 2.22±0.33 in males, and 3.61±0.53, 2.28±0.38, and 2.13±0.40 in females, respectively. In the left kidney, these measures were 3.82±0.32, 2.48±0.31, and 2.37±0.32 in males, and 3.48±0.47, 2.39±0.26, and 2.15±0.34 in females, respectively. The left kidneys of males were significantly bigger than those of females. There was a positive linear correlation between the rostrum-sacral length and ellipsoid volume of the left kidney only in males. Most of the kidneys were situated ventrally between the third to fifth lumbar vertebras. The right renal artery was situated ventrally to third lumbar vertebra and the left artery to the fourth. The results of the present study contribute to the field of comparative and applied anatomy. 3,83 ± 0,46, 2,42 ± 0,22 e 2,22 ± 0,33 em machos e 3,61 ± 0,53, 2,28 ± 0,38 e 2,13 ± 0,40 em fêmeas, respectivamente.

As dissecções foram realizadas em 40 gatos adultos, obtidos de necropsias sem evidência de patologia renal macroscópica. Medidas renais (comprimento, largura e espessura), comprimento e origem das artérias renais e ramos principais foram obtidos. O comprimento, a largura e a espessura do rim direito (cm) foram

“…In the study of Debruyn et al (2013), male cats (4.29 ± 0.40cm) tended to have larger kidneys than females (3.64 ± 0.32cm). This corresponds to the study of Shiroma et al (1999) and partially to the results obtained in this study because de difference was observed only in left kidney.…”

“…10 In both studies, the renal length was measured ultrasonographically by use of a 5-or 8-MHz curvilinear transducer. Results of a study 15 involving healthy Ragdolls likewise indicated a strong positive correlation (r = 0.71; P < 0.001) between body weight and renal length.

Objective: To assess the normal sonographic values of renal length and cortical thickness in healthy adults and establish reference ranges in our population for comparison when examining renal disease. Subjects and Methods: Sonographic assessment of renal length and cortical thickness were performed from January 2006 to December 2011 in 252 healthy individuals who were self-referred to the El-Reshaid Renal Clinic in Kuwait. They were screened for the absence of renal abnormalities. Weight and height were measured, and body mass index (BMI) and body surface area calculated. Patients were divided into 5 age groups: 18-30, 31-40, 41-50, 51-60 and 61 -80 years, in order to generate reference graphs for renal length and cortical thickness. Results: The mean renal lengths for the right and left kidney were 10.68 ± 1.4 and 10.71 ± 1.0 cm, respectively (p = 0.56) without a significant change with age. The minimum cortical thickness was 0.6 cm. The renal length correlated with the weight of the patients (p < 0.01) and their BMI (p < 0.01) but not with their height. There was no difference in renal size or cortical thickness in patients older than 60 years despite an age-related decline in the glomerular filtration rate (p < 0.001). Conclusions: Renal length and cortical thickness did not vary significantly with age. Renal length correlated well with weight and BMI but not with height. Hence, establishing normal ranges of renal parameters is essential for comparison in situations where possible renal disease is being investigated.
