Abstract
The echo contrast solution SH U 454 was injected through an ureteral stent into the upper urinary tract ex vivo in human cadaver kidneys and in vivo in kidneys of pigs. Small amounts of this solution gave excellent echogenic contrast to demonstrate the renal pelvis and calices ultrasonographically in percutaneous examination and ex vivo sonography. This sonographic contrast agent promises to be useful for non-roentgenologic voiding cystograms and antegrade or retrograde pyelography.
