This study showed the outcome of the intravenous pyelogram performed on 54 cases of ureteral stone treated at Kyungpook National University Hospital. Two-thirds of the 54 cases were male and the majority of the subjects belonged to the age group, 20~40. The predominant location was found to be single, in most cases unilateral, and 41 cases were located lower one-third of ureter. Through the intravenous pyelogram, the stasis of urine above the stone proved to be hydroneprosis and hydroureter. The above phenomena were clearer when the size of the stone was more than 0.5cm. Renal atrophy used did not show up due to the uretera stone.
