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

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

What is the definition or description of: ultrasound of kidneys shows stone?

What is the definition or description of: ultrasound of kidneys shows stone?

Usually definitive.: Ultrasound shows the renal outlines, partly because they are surrounded by fat. Calcific densities are shown by us as highly reflective abnormalities, and there is not much question. The presence of calcific densities in the kidneys makes the diagnosis of stone very likely.

Does a CT or ultrasound always show kidney stones?

Does a CT or ultrasound always show kidney stones?

No: Ct and ultrasound does not "always" show kidney stones. The resolution may not be sensitive enough to see very small stones less than 2 to 3 mm. Depending on the thickness of the images on the ct scan, a stone may be potentially missed between the images taken by the ct scanner. Ultrasound may also over-read or miss very small stones as well. Overall though, the detection rate is still very hi. ...Read more

Seriously- renal stones are the result of postive and negatively charged particles in urine binding together and precipitating as solids- most frequently as calcium- oxalate. This happens most often when the urine is concentrated- ie when you are dehydrated. And trying to pass these stones from the kidney to the bladder is incredibly painful. ...Read more
