[Thromboembolism and tumor embolism of the pulmonary artery as a cause of death in oncourologic diseases].

The autopsy material of pathological departments of Leningrad and Petrozavodsk for 1953-1980 was studied. Thromboembolism of the pulmonary artery was found to be the cause of death in renal carcinoma in 19 (1.5%) cases out of 1248 fatalities due to this carcinoma, in carcinoma of the renal pelvis and ureter in 1 (1.3%) out of 75, in urinary bladder carcinoma in 14 (1.5%) out of 918, in prostate gland carcinoma in 17 (2.8%) out of 600 cases. The source of thromboembolus in renal carcinoma and renal pelvis carcinoma most frequently was a thrombus of the lower vena cava, in the urinary bladder carcinoma that of femoral veins, in prostate gland carcinoma that of the small pelvis veins. Among the causes of death in renal carcinoma, tumor embolism of the pulmonary artery was observed in 7 (0.6%) cases.
