Excretory urography was performed on eight healthy minipigs to evaluate radiographic anatomical status and excretive function of the urinary tracts and to get an optimal procedure. The right and left kidneys were located in T13~L4 and T12~L3.5, respectively. The left kidneys were located more cranially than the right. The average lengths and widths of kidneys were 8.50±0.58 (mean±SD) and 4.30±0.39 cm on the ventrodorsal projection and 8.70±0.76 and 4.10±0.40 cm on the lateral projection, respectively. The lengths of kidneys were twice the width. When the lengths of kidneys were compared with lengths of the second lumbar vertebras, the ratios of kidney lengths to L2 lengths were 3.62±0.30 on the ventrodorsal projection and 3.63±1.10 on the lateral projection. The lengths and widths of renal pelvis including major calices were 4.01±0.46 and 2.20±0.41 cm, respectively. The lengths and widths of minor calices were 0.49±0.06 and 0.10±0.01 cm. The lengths and widths of the ureters were 12.25±2.05 and 2.94±0.86 cm. The nephrogram stage was reached in 3~5 minutes, and the pyelogram phase in 5~15 minutes individually after injection of contrast medium. The result of this study shows similar information and procedure of excretory urography for other laboratory animals and leads to the potential use of this method for minipigs.
