    Abstract:
    Twenty-five primary ureteral 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 18 males and 7 females (2.6: 1), and average age was 63.04 years old. The major symptom was hematuria. The majority of the patients were admitted to our clinic within 6 months from manifestation of symptoms. The major finding of IVP was non-functioning kidney. The positive rate of urinary cytology was 63.2%. Total nephroureterectomy with bladder cuff was performed in 21 out of 23 cases. Histologically, 22 cases were transitional cell carcinoma and one case was squamous cell carcinoma. Simultaneous urothelial tumor was found in 13 cases in the bladder. Most of the ureteral tumors (63.6%) were found in the lower third segment of the ureter. Subsequent urothelial tumors were seen in 3 bladders and one urethra out of 22 cases receiving surgical treatment in the follow-up period. The 5-year survival rate by actuarial method was 39.4%. Among several factors, grade and stage of tumor were the most influencing factors for prognosis. An effective method of post-operative treatment could not be established.
