Increased renal cortical echogenicity does not always indicate chronic kidney disease
Echogenicity of the renal cortex relative to liver or spleen can be evaluated both qualitatively and quantitatively, though qualitative method is commonly used. Normal renal cortex is usually hypoechoic (less […]
Bilateral hydronephrosis with a stone in the urinary bladder
In the first image, you can see bilateral severe hydronephrosis as evidenced by the dilated collecting system filled with anechoic (black) urine exerting pressure on the renal parenchyma. Second image […]
Hydronephrosis
On the sonogram, hydronephrosis appears as branching, interconnected areas of decreased echogenicity (anechoic or black in general, indicating the presence of fluid) in the renal collecting system. The source of […]
