Unilateral tubular obstruction: an unusual complication of urographic contrast media.
OBJECTIVE
Our purpose was to report our experience with four patients with renal colic who had a rare unilateral complication from urographic contrast media, with a dense and striated nephrogram affecting only the healthy kidney. All cases were reversible.


CONCLUSIONS
An unusual complication of urography with a characteristic radiologic appearance is presented. This complication was transient and reversible in our patients. Unilateral tubular blockage induced by a contrast agent must be considered when the contralateral kidney shows evidence of ureteral obstruction.
