[A clinical study of tumor of the renal pelvis and ureter].
We report 54 patients with urothelial tumors in upper urinary tract admitted to our hospital between July, 1962 and December, 1985. The patients consisted of 38 males and 16 females; side their ages ranged from 47 to 88 years with a mean of 63.4 years. The affected side was the right side in 21 cases, and the left side in 33 cases. Macro-or microhematuria was observed in 87% of the patients. Pathologically, 53 of the patients had transitional cell carcinoma and 1 had papilloma. Six patients had a past history of bladder tumor. Simultaneous bladder tumor was identified in 10 cases. Vesical recurrence was observed in 5 cases. Total nephroureterectomy with bladder cuff resection was employed as the surgical method in 21 cases, and total nephrectomy without bladder cuff resection in 11 patients. The actual five-year survival rate was 53% for all the patients; 52% for patients with renal pelvic tumors, 75% for those with ureteral tumors and 15% for those with renal pelvic and ureteral tumors. The patients who received nephroureterectomy had a postoperative survival rate similar to that of those who received nephroureterectomy with bladder cuff resection. A simultaneous bladder tumor lowered the survival rate.
