102 cases of renal pelvic and ureteral tumors treated at Osaka University Hospital between 1957 and 1984, were reviewed retrospectively. They consisted of 44 renal pelvic tumors, 37 ureteral tumors and 21 renal pelvic and ureteral tumors. The incidence of these tumors was 0.16% among all new out-patients. Patients ranged in age from 38 to 81 years old (average: 59.6). There were 82 males and 20 females, the ratio being 4.1:1.0. The involved side was left in 48 and right in 51. Three cases were bilateral. The most frequent symptom was macrohematuria, which was seen in 79 cases (77.5%). The major finding of IVP was non-visualizing kidney, which was seen in 52 cases (51.0%). Positive urinary cytology was obtained in 34 cases (54.0%). As the surgical method, total nephroureterectomy with bladder cuff was performed in 72 cases (72.0%), nephroureterectomy and total cystectomy in 4, nephroureterectomy in 10, nephrectomy in 11 and distal ureterectomy with ureterocystoneostomy in one case. Histologically, 97 were with transitional cell carcinoma and 5 were with squamous cell carcinoma. Simultaneous urothelial tumors were seen in the bladder of 12 patients. Subsequent bladder tumors were found in 27 cases in the follow-up period. Over-all survival rates (Kaplan-Meier) at 1, 3, 5 and 10 years were 70.8%, 45.1%, 39.0% and 30.6%, respectively.
