What can be ruled out by a normal ultrasound of both kidneys and renal arteries?

Normal dual kidney and renal artery ultrasound can roughly rule out kidney stones, renal occupying lesions, etc., as well as renal vascular stenosis and other vascular diseases.
Normal dual kidney ultrasound can check whether the patient has more obvious kidney stones, as well as more obvious renal occupying lesions, such as renal cysts and renal tumors, etc. Therefore, normal dual kidney ultrasound can roughly exclude kidney stones, renal cysts and renal tumors.
Renal artery ultrasound mainly examines the arteries of the kidneys, which can observe whether the walls of the renal blood vessels are smooth, whether the alignment is normal, whether the inner diameter size is normal, as well as the direction and flow rate of the blood in the blood vessels, etc. Therefore, a normal renal artery ultrasound can roughly exclude renal vascular diseases, such as stenosis and so on.
A single examination often can not make a clear judgment, if the patient is not feeling well, it is recommended to actively seek medical treatment in regular hospitals to avoid delaying the condition and causing adverse consequences.
