title: Ultrasonic demonstration of renal vein thrombosis.
abstract: The sonographic findings of renal vein thrombosis are described in a patient examined for pain in the upper right abdomen. Since sonographic findings of the kidney itself are nonspecific, as are clinical appearance, laboratory data, and excretory urography, direct sonographic visualization of thrombus within the lumen of the renal vein and the inferior vena cava is of major importance in the diagnosis of renal vein thrombosis.
