Sonogram (Definition)

An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more

30 yr old female. Had renal ultrasound for micro hematuria. Left ureter jet wasn't firing. Kidney blood test normal. Could this be cancer?

30 yr old female. Had renal ultrasound for micro hematuria. Left ureter jet wasn't firing. Kidney blood test normal. Could this be cancer?

Blood in urine: It is not likely that you have a cancer. I see you are taking anticoagulant meds. This can predispose to hematuria. Given the ultrasound finging of what could be slowed urine passage thru one ureter, coupled to microhematuria, I recommend further dialogue with your docs. An IVP or better, a CT-IVP is a valuable next test. ...Read more

I was sent to get a blood test because of kidney stones that a sonogram revealed I have. My results show that my MPV  is high at 12.7 Is that normal?

Platelets: MPV=mean platelet volume This is a little used value in thehemograom, with only weak correlation with disease states. Like red cells, younger platelets tend to be bigger, and stress reactions may prompt earlier release from the marrow. Many possible causes, but little utility in isolation. ...Read more
