Background
Urinary diseases are very common in emergency departments,
but can mimic other diseases (appendicitis,
diverticulitis,
cholecystitis).
The radiologists use imaging techniques to enable screening of urinary origin.
Renal ultrasound is the test of choice to exclude urinary tract obstruction and appropriate in patients for whom exposure to radiation or contrast is undesirable (renal insufficiency,
children,
pregnant women)
We summarize the use of radiologic imaging in urinary tract infections,
especially in complicated cases with emphysematous pyelonephritis or renal abscess.
In ureteral colic,
the diagnostic signs are discussed and a checklist is provided.
The renal injury appears in 10% of blunt abdominal traumatic injuries and renal imaging is indicated in macroscopic hematuria,
penetrating trauma and shock.
CT with contrast detect active hemorrhage and urinary extravasation.
Vascular pathology is reviewed with special focus in Wünderlich syndrome as well as arterial and venous thrombosis.
