The review of normal intravenous pyelography can give us important criteria of the diseases of the urinary system and the adjacent organs. Authors analyzed 200 cases of intraveous pyelography of normal Korean adults and measured the following points; the length of kidneys, the distance from midline to both poles, the slope degree of longitudinal axis, the ureteral length and width, the shortest distance from midline to abdominal ureters, the longest distance from midline to prelvic ureters, and configuration of urinary bladder. The results were obtained as follows: 1. The average length of kidneys in adult male was 12.53$pm$0.78cm on right, 12.83$pm$0.82cm on left; in adult female, 12.08$pm$0.72cm on right, 12.46$pm$0.73cm on left. In the age distribution, the length gradually became shorter by getting old. In 20% o f cases, right kidney was longer than left. 2. The average distance from both the renal poles to midline was longer in male compared to female. The distance from upper pole to the midline was longer in left side than right in male, but in the lower pole, there was no difference in both sexes. 3. The slope degree of the renal longitudinal axis was larger in male than in female, and larger in right kidney compared to left. 4. The length of ureter was longer on left, but there was no remarkable difference between both sexes. 5. The shortest distance from midline to abdominal ureter, there was no remarkable difference between both sexes and also between right and left side. But concerning the longest distance from midline to pelvice urter, it was longer I female; and especially in female, right side was shorter than left. 6. The longitudinal diameter of urinary bladder was longer in male, but horizontal diameter was longer in female.
