Statistical studies were made on 43 cases who died of urinary bladder cancer during the period of 10 years from 1961 to 1970. Special attention was paid to the causes of death and complications. A similar study was done on 690 cases recorded in the Annual of the Pathological Autopsy cases in Japan during the past 9 years from 1961 to 1969. 1) Direct causes of death: i) 15 (34.9%) in our cases and 39.4% of the cases of Ann. Path. Aut. cases Jap. died of urinary bladder cancer itself. ii) 8 (18.6%) in our cases and 18.8% of the cases of Ann. Path. cases Jap. died of renal insufficiency. 2) Complications: In our cases pyelonephritis was seen in 39.5%, hydronephrosis in 34.9% and, in the cases of Ann. Path. cases Jap., the former in 44.6% and the latter in 27.1%. An autopsy survey of the bladder cancer was made on 8 of our autopsized cases. Pyelonephritis or hydronephrosis was seen in 6 of the 8 cases : 2 in cancerous death and 4 in noncancerous death, wherein all of the 4 noncancerous deaths were complicated with either or both of these complications. The high incidence of complications in the upper urinary tracts was verified in our autopsiy cases. This will alarm us for the sincere necessity of examination for and treatment of these complications, hydronephrosis and pyelonephritis, in the cases of bladder cancer.
