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

Can a ultrasound show a kidney stone blockage thanks?

Can a ultrasound show a kidney stone blockage thanks?

Yes, depends on seve: If the blockage is complete & urine backs up into the kidneys, you can get a condition called hydronephrosis. This can be detected on ultrasound due to the dilation of the ducts in the kidneys (like stepping on a garden hose- water backs up & bulges). Ultrasound can miss a kidney stone due to its location or size; however, it can detect the *effects* of a kidney stone, by which diagnosis is made. ...Read more
