Abstract

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 $T13{\sim}L4$and $T12{\sim}L3.5$, respectively. The left kidneys were located more cra-nially than the right. The everage lengths and widths of kidneys were $8.50{\pm}0.58$ $(mean{\pm}SD)$and $4.30{\pm}0.39$ cm on the ventrodorsal projection and $8.70{\pm}0.76$, and $4.10{\pm}0.40$ cm on the lateral projection, respectively. The lengths of kidneys were twice the width. When the lengths of kidneys were com-pared with lengths of the second lumbar vertebras, the ratios of kidney lengths to L2 lengths were $3.62{\pm}0.30$ on the ventrodorsal projection and $3.63{\pm}1.10$ on the lateral projection. The lengths and 쟝손 of renal pelvis including major calices were $4.01{\pm}0.46$, and 2.20{\pm}0.41$ cm, respectively. The lengths and 쟝손 of minor calices were $0.49{\pm}0.06$, and $0.10{\pm}0.01$ cm. The lengths and widths of the ureters were $12.25{\pm}2.05$, and 2.94{\pm}0.86$ cm. The nephrogram stage was reached in 3{\sim}5$ minutes, and the pyelogram phase in $5{\sim}15$ minutes individually after injection of contrast medium. The result of this study shows similar information and procedure of excretory urography for other laboratory ani-mals and leads to the potential use of this method for minipigs.
