미니돼지에서 정상 방사선 해부학과 배설성 기능을 평가하기 위해 배설성요로조영술을 실시하였다. 오른쪽 신장과 왼쪽 신장은 각각 $T13{sim}L4$, $T12{sim}L3.5$에 위치하였으며, dhlsWHr 신장이 dhfmsWHr 신장보다 두측에 존재하였다. 신장의 길이와 너비는 복배상에서 각각 $8.50{pm}0.58$ $(mean{pm}SD)$, $4.30{pm}0.39$ cm 이었다. 외측상에서 각각 $8.70{pm}0.76$, $4.10{pm}0.40$ cm 이었다. 신장의 길이는 너비의 약 두 배이었다. 두 번째 요추 몸퉁의 길이와 신장의 길이를 비교하였을 때, 복배상에서는 그 비율이 $3.62{pm}0.30$, 외측상에서는 $3.63{pm}1.10$로 측정되었다. 신우의 길이와 너비는 각각 $4.01{pm}0.46$, 2.20{pm}0.41$ cm 이었다. 콩팥잔의 길이와 너비는 각각 $0.49{pm}0.06$, $0.10{pm}0.01$ cm 이었다. 요관의 길이와 너비는 각각 $12.25{pm}2.05$, 2.94{pm}0.86$ cm 이었다. 콩팥조영사진은 3{sim}5$분에 관찰되었고, 신우조영사진은 $5{sim}15$분에 관찰되었다. 배설성요로조영술은 미니돼지 비뇨기계의 정상 방사선학적 해부와 배설성 기능에 대해 전반적으로 평가할 수 있는 간단한 방법이다.
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.
