Three cases of "shock kidneys" were demonstrated by excretory urography. A dense, prolonged nephrogram and decreased excretion of the contrast material during the hypotensive episode were seen. In addition, our cases show bilaterally small kidneys without evidence of underlying chronic renal disease, which we consider to be a normal physiologic response.
