Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body.

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.

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

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
