[Ultrasonographic evaluation of the urinary system, liver and uterus of Cebus apella monkey.] Avaliação ultra-sonográfica do sistema urinário, fígado e útero do macaco-prego, Cebus apella. Pesquisa Veterinária Brasileira 27(9):377-382. Departamento de Cirurgia, Faculdade de Medicina Veterinária e Zootecnia, Universidade de São Paulo, Av. Prof. Dr. Orlando Marques de Paiva 87, São Paulo, SP 05508-270, Brazil. E-mail: flaviovet@usp.br The Brown Capuchin, Cebus apella, has a wide distribution in the northern and southern Brazilian Amazon region and in the Cerrado (savanna). These monkeys are usually submitted to predatory chase, increasing the need for preservation of this wild animal species. An ultrasonographic examination of 10 Brown Capuchins was made in order to describe the normal ultrasonographic anatomy of their abdominal cavity. The urinary bladder revealed its wall thickness with an average of 0.2cm, the topographic situation of which allowed close relation with the wall of uterus and descendent colon. Using caudal abdominal scan, images of aorta, caudal vena cava and right iliac vein were obtained. Liver was accessible for examination by sagittal and cross-section ultrasound, allowing visualization of gallbladder and hepatic vessels. Renal scan allowed accuracy to evidence the echogenicity differences between pelvis, renal sinus, as well as the cortical-medullary relationship. The mean length of the kidneys was 6.24±0.31cm, and no significant differences were observed between left and right kidney length (Student’s t-test and ANOVA). The renal volume obtained was 2.37±0.18cm3. Correlation Coefficients of Pearson between right and left renal length and between right and left renal volume were r = 0.74 and 0.51. Mean thickness for cortical and medullar regions was 0.75±0.11 and 0.39±0.06cm, respectively. Correlation Coefficient of corticomedullar relation between right and left renal was r = 0.19. Examination by ultrasound was considered an efficient, non-invasive, fast and repeatable technique which provides useful data for clinicians and surgeons engaged in wild animal medicine.
