Dehydration in urography: is it really necessary?
The use of dehydration in patients undergoing intravenous urography remains widespread, despite evidence that it may be dangerous and despite lack of evidence of any effect on the urinary concentration of contrast media. In total, 100 patients were studied, having been allocated randomly into two groups, one of which had undergone dehydration, the other group being normally hydrated. No significant difference in the quality of the urograms was detected. It is suggested that the practice of dehydration in preparation is unnecessary and should no longer be undertaken.
