large renal mass was found covered by many dilated and engorged veins. Prior to mobilizing the kidney the ureter was explored and found to be normal for a few centimeters distal to the renal pelvis. At that point the ureter entered an oval mass approximately 3 by 5 cm. in size which was made up of innumerable dilated and engorged blood vessels. Believing these extensive varicosities to account for the "papillary" appearance of the mass in the ureter, the ureter was transected distally and nephrectomy
performed. In the course of preparing the renal pedicle it was necessary to milk a tumor thrombus the size of one's index finger from the proximal portion of the vena cava back through the renal vein prior to clamping and ligating the renal vein separately. Upon opening the ureter at the site in question the varicosities had collapsed. Protruding into the lumen was a small solid tumor histologically identical to the renal adenocarcinoma.
