Predictive role of duplex Doppler ultrasonography in the diagnosis of acute renal obstruction in patients with unilateral renal colic

Abstract

Intrarenal Doppler ultrasonography represents a sensitive and highly specific test that can significantly contribute to the diagnosis of obstruction in patients with acute renal colic. It should be used as the first line imaging method in suspected acute renal colic, as well as for patients with renal insufficiency, pregnant women or for patients with adverse reactions to contrast media
