Differences of Renal Parenchymal Attenuation for Acutely Obstructed and Unobstructed Kidneys on Unenhanced Helical CT

A Useful Secondary Sign?

OBJECTIVE. The purpose of this study was to ascertain whether the difference in attenuation frequently noted on unenhanced helical CT scans between a patient's acutely obstructed kidney and the unobstructed kidney is a reliable secondary sign of acute renal obstruction.

CONCLUSION. In 95% of patients with acute renal obstruction, the affected kidney was less dense than the unobstructed kidney. When visually detected by radiologists using CT, this difference in density was at least two standard deviations above normal, making it a reliable secondary sign for acute obstruction.
