“…Ultrasonographic prostatic measurements are more accurate and reliable than radiologic ones because the margins of the prostate are better outlined, and because there is no magnification effect, as opposed to radiology (Atalan et al., ). However, although ultrasonography of the prostate gland is supposed to be easy compared with other intra‐abdominal organs (Nyland et al., ; Cruz‐Arambulo and Wrigley, ), our results show between‐day and within‐day coefficient of variations being to reach 11.5% for the less‐trained observer. Standard deviation values presented in Table were rather low in comparison with the mean values (Table ), suggesting little intra‐observer variation; however, data show significant differences between the three observers for the majority of the measurements (Table ).…”

“…It is an encapsulated, bilobed, and bilaterally symmetrical ovoid gland, located caudal to the bladder ( Vesica urinaria ), encircling the proximal ( Pars prostatica ) urethra ( Urethra masculina ). Most prostatic diseases in dogs are associated with prostatomegaly (Feeney et al., ; Barsanti and Finco, ; Cruz‐Arambulo and Wrigley, ). There are several clinical methods to evaluate prostate size in the dog, including rectal palpation, radiography, transabdominal ultrasonography (Cartee and Rowles, ; Blum et al., ; Vilman et al., ; Ruel et al., ), transrectal ultrasonography (Bartsch et al., ; Hastak et al., ), computed tomography (CT) (Peeling and Griffiths, ) and magnetic resonance imaging (MRI) (Rahmouni et al., ).…”

Most prostatic diseases in dogs are associated with prostatomegaly, and transabdominal ultrasonography has become the imaging modality of choice for evaluation of the prostate gland in the dog. The aim of the present study was to assess the reproducibility, the repeatability and interobserver variations of sonographic measurements of prostate and to determine which measurement had the lowest variability. Length and height of prostate gland were measured on longitudinal views, width of the prostate gland and height of left and right lobes of the gland on transversal views. The within-day and between-day variabilities of the prostatic parameters were determined by performing 1350 (270 length, 270 height, 270 width, 270 height of right lobe and 270 height of left lobe) examinations on ten healthy intact beagle dogs on six different days, in a two-week period (three days for the five dogs, three different days for the five others). Three observers with different levels of experience in ultrasonography performed the examinations. The lowest within-day and between-day standard deviation and coefficient of variation values were observed for the width of the prostate. The width of the gland measured on transverse frozen images seems to be the most reliable measurement for evaluating size of prostate glands in healthy dogs, although the shape, position, outline, and echogenicity of the prostate should also be assessed.

“…Previamente ao exame ultrasonográfico, foi realizada uma tricotomia na região lateral do abdômen, caudal a última costela esquerda, e no lado direito a partir do 11 o espaço intercostal (Nyland et al 2005), estendendo-se 1,5cm caudalmente à 13 a costela (Gaschen et al 2000). O mesmo procedimento foi realizado na região ventral do abdômen para facilitar a visualização ultrasonográfica da bexiga (Cruz-Arambulo & Wrigley 2003 …”

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.

Acute abdomen syndrome is an emergency in small animal practice that requires rapid diagnosis to determine the appropriate treatment. No studies have correlated the preoperative abdominal ultrasonography (US) findings with the clinical, surgical, cytopathologic, and histopathologic findings. This retrospective study was designed to evaluate abdominal US in the diagnosis of acute abdomen syndrome using surgery as a “criterion standard”. The most frequently misinterpreted lesions with US were also identified. The study included 50 dogs and cats with physical examination, an US diagnosis, US guided fine-needle aspiration cytology, intraoperative findings, and histopathology. Intraoperatively, 49 primary and 43 secondary lesions were identified. The sensitivity, specificity, and positive and negative predictive values for US were calculated. There was a good agreement between the US diagnosis and intraoperative findings of 86.9% (80/92), for both primary and secondary lesions (p < 0.0001). Cytology and histopathology examinations corroborated the US in 86.4% (n = 64/74) of primary and 66.2% of secondary (n = 49/79) lesions. Using US as the “criterion standard”, the sensitivity of abdominal palpation for identification of ascites and masses was 32.4% and 43.7%, respectively, while the specificity was 93.7% and 94.4%, respectively. Abdominal US is a useful preoperative modality for diagnosing acute abdominal diseases in dogs and cats. Care should be taken with interpretation of gastrointestinal perforation, omental tumors, and common bile duct rupture, as these lesions are frequently misinterpreted with US.
