[A clinical survey of renal pelvic and ureteral tumors associated with bladder tumor].

A clinical survey was performed on 80 cases of renal pelvic and ureteral transitional cell carcinomas we treated between January, 1963 and December, 1986. The cases included 30 of renal pelvic tumors, 17 of ureteral tumors, 3 of renal pelvic and ureteral tumors, 7 of renal pelvic and ureteral and bladder tumors, 16 of ureteral and bladder tumors and 7 of renal pelvic or ureteral tumors after treatment for bladder tumors. There were 37 cases of bladder tumors: 7 cases with preceding bladder tumors, 23 cases of synchronous bladder tumors, and 13 cases of subsequent bladder tumors. The 5-year survival for all cases was 60.2%. The 5-year survival for 43 cases unrelated with bladder tumors was 80.5% and that for 37 cases of bladder tumor was 41.6%. Therefore, there was a significant difference between these 2 groups (p less than 0.005). The 5-year survival for 50 cases without synchronous bladder tumors at first diagnosis was significantly higher than that for 23 cases with synchronous bladder tumors (p less than 0.001). Subsequent bladder tumors occurred after 2 to 48 months (mean 10 months) of the initial treatment for renal pelvic and ureteral tumors. Six of the 7 cases of preceeding bladder tumors were superficial tumors of pTa and pT1 and 3 cases had vesicoureteral reflux.
