Forty primary renal pelvic tumors treated at our University between 1963 and 1981, were reviewed retrospectively. The conclusions of this study are as follows. Sex and age distribution of the patients were 30 males and 10 females (3: 1), and average age was 60.5 years old. The major symptoms were hematuria and flank pain; however, palpable mass was rare. The majority of patients were admitted to our clinic within 6 months from manifestation of symptoms. The major findings of IVP were non-functioning kidney and filling defect. The positive rate of urinary cytology was 46.7%. Total nephroureterectomy with bladder cuff was performed in 20 out of 32 cases. Histologically, 29 cases were transitional cell carcinoma and 4 cases were squamous cell carcinoma with renal calculi. Simultaneous urothelial tumors were seen in 10 cases, 3 in the ureter and 7 in the bladder. A subsequent ureteral tumor was found in one out of 12 cases in which ureters were resected incompletely, and 7 subsequent bladder tumors were found out of 32 cases receiving surgical treatment in the follow-up period. The 5-year survival rate by the actuarial method was 75.9%. Among several factors, grade and stage of the tumor were the most influencing factors for prognosis. An effective method of post-operative treatment could not be established.
