“…This results in the imaging of imprecise organ margins (Walter et al, 1987) and failure to image the kidney in its greatest dimension (Rosenbaum et al, 1978). Felkai et al, (1992) observed that it was occasionally difficult to define the renal border at the hilus, probably because of presence of connective tissue.…”

“…The cortex and medullary thickness were also increased linearly in both the kidney. Felkai et al (1992) considered that the variation in the various renal parameters occurs due to limited visual acuity of the observer while observing an ultrasonogram. This results in the imaging of imprecise organ margins (Walter et al, 1987) and failure to image the kidney in its greatest dimension (Rosenbaum et al, 1978).…”

The present study was undertaken in six apparently healthy pups of mixed mongrel breed from the same litter, to study developmental changes using 3D ultrasound machine (Nemio-XG: Toshiba, Japan). In kidneys the cortex appeared hypoechoic and medulla was anechoic up to 3 rd month of age, where as the same was hyperechoic and medulla was hypoechoic up to end of the study (8 th month). The kidney parameters observed were length, width, circumference, cortical thickness and medullary thickness, which showed linear increase with age. In 3D appearance of the renal structures (renal pelvis, renal sinus) were clearer than 2D ultrasonogram.

“…59 In dogs, ultrasound is clinically useful for determining kidney size, with measurement in multiple planes producing an estimated renal volume that correlates well to actual renal size. [60][61][62][63] Potential inaccuracies in ultrasonographic evaluation of feline kidneys include observer visual error, imprecise border definition due to minimal capsular echo, and ultrasonographic artifacts. 64 On ultrasound the renal cortex is uniform and is hyperechoic compared to the spleen in the normal cat.…”

Objective:To assess effects of bisection nephrotomy on renal function, size, and morphology in cats over a period of 12 weeks. Study Design:Controlled, randomized, blinded experiment. Sample Population:Ten adult female cats. Methods:Glomerular filtration rate (GFR), as determined by quantitative renal scintigraphy using Results:No significant differences in mean GFR and kidney size of the operated versus unoperated kidneys were observed at any time period. Individual GFR and renal size of all except one of the cats remained within normal limits. Two additional cats had evidence of transient ureteral obstruction in the immediate post-operative period. No significant histologic abnormalities were observed in any biopsy. Conclusions:Bisection nephrotomy in normal cats did not adversely affect renal function or morphology over the three month post-operative period. Clinical Relevance:Bisection nephrotomy can be safely performed in normal feline kidneys without causing a significant deleterious effect on renal function. Studies in animals with pre-existing renal insufficiency are needed to insure no adverse effects would occur in clinical cases where this surgical procedure is warranted.

“…Alterações no formato e tamanho dos rins comumente ocorrem como resultado de muitas enfermidades renais e a detecção destas mudanças são importantes para o diagnóstico e prognóstico das renopatias (Felkai et al 1992). As mudanças anatômicas nos rins podem ser avaliadas pela radiografia (Finco et al 1998), laparoscopia (Nyland & Matoon 1995) e ultra-sonografia (Espada et al 2006).…”

“…Estudos correlacionando as medidas lineares e o volume renal com o peso canino tem sucesso limitado (Felkai et al 1992, Sampaio & Araújo 2002, Nyland et al 2005, uma vez que o tamanho do órgão pode ser superestimado em um cão adulto subnutrido, assim como subestimado em cães adultos obesos. Recentemente, temse buscado correlacionar o diâmetro longitudinal do rim com o diâmetro da artéria aorta abdominal em cães clinicamente normais, com intuito de estabelecer parâmetro de normalidade para o tamanho renal (Mareschal et al 2007).…”

ABSTRACT.-Santana E. Jr M., Beserra P.S., Brito A.B., Miranda S. The aim of this paper was to establish the relation between the kidney ecobiometry with atlanto-coccyges distance (ACD) and height (H) in adult healthy dogs, to obtain normality parameters for assessment of renal size and volume, as well as establish reference values to evaluate kidney blood perfusion by the resistivity index (RI) and pulsatility index (PI) of main renal artery. The study was applied at 22 adult dogs, 11 males and 11 females. Previously, the DAC and H of all animals were measured. For ultrasonographic examination, the ultra-sound system HDI 4000 PHILIPS equipped with a multi-frequency microconvex transducer, Color Doppler and Spectral Doppler devices was used. The animals were placed into right or left lateral decubitus position, in agreement with the kidney to be assessed. The longitudinal (LD) and dorsoventral diameters (DVD) of kidney were measured in longitudinal plane, and the transverse diameter (TD) was determined in transversal section. The renal volume (V) was automatically calculated by the ultrasound software. With Triplex Doppler, the RI and PI of right and left main renal arteries were obtained. All data were represented in mean ± SEM. Linear regression analyses were performed with renal LD, DVD, TD and V as dependent variable, and ACD and H as independent variable. RI and PI were compared between right and left renal arteries with Student's t-test. The LD, DVD, TD (cm) and V (ml) mean measurements for the left and right kidneys were: 5.24±0.27, 3.07±0.15, 3.07±0.9, 28.01±3.4 and 4.50±0.19, 2.88±0.14, 2.71±0.15, 21.27±2.6. All regression analyses were significant for the intercept and regression coefficient (P<0.01). There were statistical differences on RI and PI means between right and left renal arteries (P=0.001). The RI and PI means of left and right renal artery obtained were: 0.62±0.08 and 1.34±0.18; 0.70±0.06 and 1.62±0.13. The data obtained in the present paper can be used as parameters for evaluation of the renal size, volume and perfusion in adult dogs.INDEX TERMS: Corporal conformation, ultrasound, renal perfusion, Dopplerfluxometry.
