“…One possible reason for the wide range of normal values could have been the use of different breeds, different morphologies (i.e. brachymorphic, mesomorphic and dolichomorphic), and different body weights 3,12 …”

In a previous study, an ultrasonographic method to assess kidney size in dogs as a ratio of kidney length to aortic luminal diameter (KL/AoD ratio) was proposed. The main limitation of this method was the wide range of normal values (5.5‐9.1), which resulted in poor sensitivity and specificity. The aim of this prospective, observational, reference interval study was to determine whether the KL/AoD normal cut‐off values in a single breed (Whippets) would have a narrower range than the previously reported normal reference ranges. The influence of sex, age, weight, and side on kidney length (KL) and of sex, age, weight, and scanning plane (longitudinal vs transversal) on aortic luminal diameter (AoD) were also investigated. Thirty‐six clinically healthy Whippets (16 males, 20 females) without ultrasonographic renal lesions were included in this study. The 95% confidence interval of mean KL/AoD was found to be narrower than the previously reported range (ie, 6.3‐6.9 versus 5.5‐9.1). This was considered to be especially notable in that the KL in this breed exhibits marked sexual dimorphism. The KL/AoD ratio did not differ between right versus left sides or male versus female sexes in Whippets (P > .05). Findings from the current study provided KL/AoD ratio normal reference range cut‐off values for future use in Whippets and supported the use of breed‐specific KL/AoD ratio values for characterizing abnormal renal size in other canine breeds.

“…Most studies that present renal dimensions in dogs have methodology based on imaging methods. Some suggest indexes where the kidneys of male dogs are significantly bigger than of the females (LEE;LEOWIJUK, 1982;LOBACZ et al, 2012;MARESCHAL et al, 2007;ARAUJO, 2002;SOHN et al, 2016). In C. thous, no significant difference was found in the renal measures between sexes, when all specimens were compared and when separated by biomes.…”

Article history Cerdocyon thous is the South American canid with great geographic distribution. To the south of Ecuador, two isolated populations have been identified, living in different average temperatures and food availability. The objective was to measure the length, width, thickness and volume of the kidneys, length of renal vessels, and verify the renal skeletopy in two populations of C. thous. Kidneys and renal vessels were measured from 34 cadavers collected on highways in the Brazilian territory. From the Atlantic Forest biome (latitude 22º), 14 specimens (seven males and seven female) were analyzed, and from the Pampa biome (latitude 29º), 20 specimens (eight males and twelve female). On average, in the right antimere the kidneys measured 49.9  25.2  24.4 mm, had a volume of 16.5 cm 3 , the renal artery measured 21.3 mm and the renal vein 19.4 mm. In the left antimere, the kidneys measured 49.3  24.4  22.8 mm, with a volume of 14.6 cm 3 and the artery and vein measured 21.0 mm and 28.4 mm, respectively. The right kidney was always cranial and predominantly positioned ventrally to vertebrae L1-L3, while the left one was positioned ventrally to vertebrae L2-L4. There was no difference in the comparison between sexes or antimeres. Most renal dimensions were significantly higher in the specimens from the Pampa biome, possibly due to the body size and type of diet. This result warns of interpreting diagnoses that depend on the evaluation of the normal renal dimensions in this species.

“…Kidneys are located in the retroperitoneal region (Burk & Feneey, 2003) that performs vital functions in the body such as excreting waste products, maintaining homeostasis, blood production and utilization of mineral calcium (Fitzgerald et al, 2011). Many kidney diseases are associated with changes in kidney dimensions (Sohn et al, 2016), therefore, the knowledge of normal kidney volume is important, as it can be used for the morphological diagnosis of kidney diseases (Barrera et al, 2009) and also useful in monitoring of transplanted kidney (Nyland et al, 1997). A method introduced by Mareschal et al (2007) which is the ratio of the kidney length to the aortic luminal diameter as a means to access the kidney size, it has a drawback in the measurement of aortic luminal diameter which is greatly affected by diastolic and systolic phases of cardiac cycle.…”

The aim of this study was to determine the relationship between ultrasonographic kidney volume and modified body mass index through evaluating the kidney architectural appearance, variations between right and left kidney dimensions and correlation between ultrasonographic kidney volumes and modified body mass index in clinically healthy Nigerian indigenous dogs. The ultrasonography was performed to obtain the kidney dimensions in centimeter for the length (bipolar length), width and height of the kidney for both right and left kidneys to compute for the kidney volume in centimeter cube using the formula for the volume of an ellipsoid (L X W X H X 0.523), while the modified body mass index for dogs was obtained by taking the body weight in kilogram of each dog against the squared length of the trunk. The serum creatinine and urea parameters are within normal limits in dogs used for this study. This research revealed normal kidney architecture with hyperechoic renal capsules, hypoechoic renal cortex, anechoic medullary pyramids and hyperechoic renal pelvis. Left kidneys are significantly larger than the right kidneys and there was a weak positive correlation between right (r 2 = 0.21) and left (r 2 = 0.18) kidney volumes with modified body mass index in clinically healthy in Nigerian indigenous dogs. In conclusion, the left kidney appeared larger than the right kidney and there is a positive but weak relationship between ultrasonographic kidney volume and modified body mass index in healthy Nigerian indigenous dogs.
