[A clinical survey of 7 cases with primary ureteral tumor: experiences in a year].
Seven cases of primary ureteral tumors treated at Nagaoka Koseiren Chuo General Hospital in 1983 were reviewed retrospectively. The incidence of primary ureteral tumors among the out-patients in the urologic clinic of the hospital was 0.22% and the incidence among the in-patients was 1.65%. The patient's age ranged from 45 to 83 years (average: 59.14 years old). The ratio of male to female was 2.5: 1.0. The left ureter and the lower third of the ureter were involved more frequently than the others. The most common symptom was colicky flank pain (57% of the cases), which was followed by macroscopic hematuria. On IVP, 5 of the 7 cases showed a non-functioning kidney or hydronephrosis, but the others showed filling defects in the ureteral lumen without hydronephrosis. Diagnostic accuracy of CT was 14.3%. Diagnostic accuracy of urine cytology was 42.9% and the false negative rate was the same. Six of the 7 cases underwent total nephroureterectomy with bladder cuff excision. The higher the grade and stage of the tumor, the poorer the prognosis tended to be.
