Renal cell carcinoma extending into vena cava and right atrium.

We report on a patient who underwent complete removal of a renal cell carcinoma extending into the vena cava and the right atrium. A review of the literature confirms the rarity of vena caval obstructive symptoms. Emphasis is on preoperative diagnosis, thoracoabdominal exposure, and team approach. Survival rates warrant aggressive surgical treatment in these patients.

Radioisotope penogram in diagnosis of vasculogenic impotence.

The radioisotope penogram is noninvasive and gives a dynamic evaluation of the arterial supply, venous drainage, and blood flow in the corporeal bodies. The penogram is a valuable adjunct in evaluation of patients with vasculogenic impotence.
