  • Early Diagnosis of Chronic Kidney Disease in Asymptomatic Cats - Association of Renal Doppler Resistive Index with Elevated Symmetric Dimethylarginine
    Rafaelle Cristine Dea Gerez, Fabiana Rodrigues de Freitas, Rosangela Locatelli Dittrich, Camila Marinelli Martins, Tilde Rodrigues Froes
    Acta Scientiae Veterinariae, 2026
    Background: Chronic kidney disease (CKD) in cats often progresses silently, making early diagnosis challenging. Symmetric dimethylarginine (sSDMA) is a sensitive biomarker for early renal dysfunction, while the resistive index (RI), obtained via Doppler ultrasonography, reflects renal vascular resistance. Combining these tools may improve early CKD detection. This study aimed to evaluate the correlation of RI with sSDMA in asymptomatic cats. Materials, Methods & Results: A prospective, blinded cohort study assessed the correlation between renal RI and sSDMA in 101 clinically asymptomatic cats. Examinations were performed without sedation, with manual restraint, and approved by the Federal University of Paraná's Animal Ethics Committee. Triplex Doppler ultrasonography used a GE Logic 5 machine with a 7.5-12 MHz linear transducer. B-mode assessed renal morphology, followed by color and pulsed Doppler for vasculature and interlobar arteries. RI was automatically calculated from three waveforms per kidney. An RI ≥0.59 (left) or ≥0.54 (right) was considered elevated. Blood samples were collected from the jugular vein. Creatinine and sSDMA were measured at IDEXX Laboratories (São Paulo, Brazil) using liquid chromatography-mass spectrometry. Urine was collected via cystocentesis. sSDMA values ≥ 14 μg/dL were considered elevated. Cats were grouped by sSDMA levels. Statistical analysis used SPSS 21.0, with P < 0.05 set as significant. Reliable RI measurements were obtained in 91 cats; 10 were excluded due to poor waveform acquisition (e.g., patient movement, panting, poor corticomedullary definition). Mean RI was 0.61 ± 0.07 (left) and 0.62 ± 0.07 (right), with no significant difference. Increased RI was seen in 55.9% (47/84) of left kidneys and 86% (74/86) of right kidneys. Elevated sSDMA was detected in 14.9% (15/101) of cats. A statistically significant correlation was found between elevated RI in the right kidney and increased sSDMA (P = 0.001), but not the left (P = 0.246). Creatinine also positively correlated with elevated sSDMA (P = 0.022), supporting the link between renal hemodynamic changes and early biochemical markers. These results suggest RI, particularly in the right kidney, may be a useful non-invasive parameter for early CKD detection in cats, especially with sSDMA. Discussion: While renal ultrasonography is common in cats, few studies explore RI's diagnostic potential in asymptomatic animals. Doppler ultrasonography was feasible but sometimes limited by patient stress, obesity, and altered renal morphology, affecting waveform quality. No significant difference was found between right and left kidney RI values, though some cats showed inter-kidney discrepancies, possibly indicating unilateral disease. Mean RI values were normal but near early CKD values.The significant correlation between elevated RI in the right kidney and increased sSDMA was not observed in the left. The asymmetry is unclear, but extrarenal factors and comorbidities might influence both RI and sSDMA. Despite limitations, creatinine also correlated positively with sSDMA, supporting its reliability in early renal assessment. RI should not be a standalone CKD screening method but a complementary tool, especially with sSDMA. Bilateral assessment is recommended, and interpretation should be cautious with morphological abnormalities or poor patient cooperation. Overall, RI measurement is feasible in unsedated cats and may aid early detection of renal changes in subclinical disease. Keywords: feline, resistive index, doppler, kidney, SDMA.

    Acta Scientiae Veterinariae, 2024
    Background: An essential component in the treatment of critically ill patients is volume replacement, but excessive intravascular fluid administration is associated with increased morbidity and mortality. Therefore, this intervention is only beneficial in patients who are fluid responsive, that is, when the individual has an increase in at least 15% of the stroke volume after a volume challenge administration. In addition, one of the determinants of fluid responsiveness is the systolic function, associated with the dynamic interactions between intravascular volume (preload) and vascular tone (afterload). Within this context, the aim of this study is to evaluate if conventional and advanced echocardiographic parameters of right ventricular longitudinal systolic function can assess fluid responsiveness in healthy spontaneously breathing dogs. The hypothesis was that some of these parameters would differ between responsive and non-responsive animals and could be used as a complementary measure for assessment of fluid responsiveness. Materials, Methods &amp; Results: This is a prospective study with 22 healthy dogs over 1 year of age included. The animals were referred to the Veterinary Medical Teaching Hospital of the Federal University of Paraná (UFPR) for elective neutering procedure. All dogs underwent conventional and advanced echocardiographic examination before and after administration of a volume challenge with 10 mL/kg lactate ringer intravenously for 20 min. The parameters evaluated were the fractional area change (FAC), the tricuspid annular plane systolic excursion (TAPSE), free wall longitudinal strain (LSt), and tissue motion annular displacement (TMAD). Based on the aortic velocity integral time variation, 31.82% of dogs were considered responsive and 68.18% were non-responsive to the volume challenge. For conventional echocardiography, TAPSE (mm/kg) &gt; 1.35 (P = 0.018) had a good combination of sensitivity (85.71%) and specificity (86.67%), area under the curve value (0.814) and a relative smaller gray zone interval (1.04-1.66) for the identification of responsive dogs before volume challenge. Although, TAPSE (mm/m2) was also higher in the responsive dogs (P = 0.023) before volume challenge. As for advanced echocardiography, the TMAD (mm/kg) &gt; 0.75 (P = 0.010) after volume challenge had the best combination of sensitivity (85.71%) and specificity (86.67%), area under the curve value (0.852) and a relative smaller gray zone interval (0.57-0.92) for the identification of responsive dogs. The LSt (%) and TMAD (mm/m2) were also significantly higher in responsive dogs (P = 0.031; P = 0.011) after volume challenge. Discussion: Some of the echocardiographic parameters for assessing right ventricular systolic function differed between responsive and non-responsive dogs proving to been useful in the fluid responsiveness evaluation. To the author's knowledge, this is the 1st study to investigate the right ventricular systolic function in the assessment of fluid responsiveness in healthy, spontaneously breathing dogs. TAPSE and TMAD showed some advantages in terms of execution, although TAPSE (mm/kg) &gt; 1.35 before the volume challenge had the power to predict fluid responsiveness without the need of a fluid administration, which can be seen as a great advantage, especially for patients with volume overload. However, it is also necessary to perform this type of evaluation in individuals with hemodynamic alterations to allow better understand the applicability of these techniques. Keywords: canine, longitudinal strain, stroke volume, tissue motion annular displacement.
  • The use of agitated saline as contrast agent in a contrast-enhanced cystosonography for detection of urinary bladder rupture in animal cadavers

    Journal of Veterinary Emergency and Critical Care, 2023
    OBJECTIVE To determine the value of microbubble contrast cystosonography in the diagnosis of bladder rupture in animals. DESIGN Prospective, method comparison study from November 2019 to October 2020. SETTING University teaching hospital. ANIMALS Thirty-four ethically sourced cadavers of dogs, rats, and rabbits. INTERVENTIONS In a prospective and blinded study, the cadavers were divided into 2 randomized groups: with bladder rupture (CR), and without bladder rupture (SR). Urinary catheterization was performed in all cadavers. Through the urethral catheter, bladders in CR group were ruptured using a rigid stainless steel guide wire. Microbubble contrast was infused into the bladder through the urethral catheter, while a single, blinded observer sonographically assessed the bladder. The time to diagnosis and the number of attempts needed for diagnosis were recorded. MEASUREMENTS AND MAIN RESULTS The study included cadavers of 16 female Wistar rats, 6 female dogs, 11 male dogs, and 1 male rabbit. Time to diagnosis in dogs (2.25 ± 0.91 min) was statistically higher when compared to rats (1.15 ± 0.75 min; P = 0.03). Of the 34 cases, incorrect diagnosis of bladder rupture was made in only 2 dogs (6%), indicating a diagnostic sensitivity of 88.88%, specificity of 100%, and an accuracy of 94%. The positive predictive value was 1 and the negative predictive value was 0.9. CONCLUSIONS Our study showed that the described method is accurate, sensitive, and specific for the detection of bladder rupture in animal cadavers of different species, size, and sex.

    Plos One, 2022
    The purpose of this study was to evaluate and compare positive cystography techniques at 5%, 10%, and 20%, as well as three different double-contrast protocols for detecting radiolucent uroliths with a diameter of less than 3.0 mm in dogs. Six cadavers were used, one was selected at random to represent the negative control, and the others were submitted to urolith implantation in the bladder by urethral catheter. Three radiology professionals blindly accessed ventrodorsal and -lateral projections of each test. Contrast at 20% showed greater diagnostic sensitivity, but with greater difficulty identifying the number and size of the uroliths. Consequently, double-contrast techniques are better and should be used for diagnostic and therapeutic planning. Sensitivity and specificity tests demonstrated that positive 5% cystography and different concentrations of double contrast obtained better results in terms of sensitivity and specificity. However, due to the presence of a greater amount of artifacts in the 5% cystography, it is suggested that double contrast is used for this purpose, especially with the removal of contrast excess (protocol 2).
