Estudo guiado por imagem da anatomia suína como ferramenta para pesquisa e treinamento de procedimentos urológicos

Abstract

Purpose: To describe the anatomy of the swine’s urinary system using computed tomography and to discuss the role of this animal as an experimental model for urological procedures. Methods: Three male Landrace pigs underwent computed tomography and the anatomy of the urinary system and renal circulation was analyzed and described. Results: In all animals, 2 kidneys, 2 ureters and one bladder were identified. Each kidney presented a single renal artery vascularization, with a mean diameter on the right of 4.45mm and 5.31mm on the left (p<0.0001), and single renal vein drainage, with a mean diameter on the right of 5.78mm and 5.82mm on the left (p=0.0336). The average renal length was 9.85cm on the right and 10.30cm on the left (p<0.0001). The average renal volume was 113.70cm3 on the right and 109.70cm3 on the left (p<0.0001). The average length of the ureter was 19.78cm on the right and 22.08cm on the left (p<0.0001). The average bladder volume was 423.70cm3. Conclusions: The data obtained show similarities with human anatomy, suggesting the viability of the swine model for planning pre-clinical trials, basic research, refinement in experimental surgery and surgical training for urological procedures.
