Abstract
- Records of 15 patients of primary ureteral tumor which were managed in Seoul National University Hospital during 13.5 years period from January 1971 to June 1983. 1. Primary ureteral tumor comprised of 2% of all urothelial tumors and the ratio of bladder:pelvis:ureter was 40:2:1. 2. There were 11men and 4 women (ratio of 3:1) with a mean age of 62.7 years. 3. The most frequent site of ureteral tumor was the lower one third of the ureter (53%). 4. Most frequent presentation was gross hematuria. usually intermittent and painless (100%). 5. Non-visualization of the kidney was the most prevalent finding (73%) on excretory urogram. Retrograde pyelogram was necessary in 11 patients whose findings of IVP was insufficient for diagnosis, and these procedures provided definite diagnosis in 9 of 11 patients. 6. Urine cytology was positive in 4 of 13 patients. 7. Cystoscopy was performed in all patients and which revealed concomitant bladder tumor in3 patients and tumor in ureteral orifice in 2 patients. 8. There was close correlation between the grade of cellular anaplasia and the degree of invasion. 9. There were 3 recurrences (50%) in the ureteral stump in 6 patients treated by nephrectomy and partial ureterectomy.
