Thirty-three cases of primary @entity703 , i.e., 14 @entity703 , 14 @entity1698 , treated at our hospital between November, 1976 and August, 1987 are reviewed retrospectively. @entity5 occurred on the right side in 18 cases, left side in 14 cases and bilateral in one case. The @entity1 ranged in age from 33 to 77 years (average 65.7 years), the sex ratio was 4.5:1 with male predominance over female. The most frequent symptoms were gross @entity811 in 22 cases (67%). Interval from onset of initial symptoms to first visit within one month for 23 cases (70%). The major findings of excretory urograms were non-visualizing kidney in 18 cases (55%) and filling defect in 12 cases (36%). Positive urinary cytology was obtained in 18 cases (55%). Operative therapy was performed in all cases, namely, total nephroureterectomy with partial cystectomy in 21 cases (64%) and nephrectomy with transurethral ureterectomy in 7 cases (21%). Histopathologically, all cases but one case of @entity957 were @entity1606 . Subsequent @entity150 were found in 10 cases (30%). The overall survival rate at 1, 3 and 5 years were 84%, 68% and 61%, respectively by Kaplan-Meier method. In this series, grade and stage of @entity5 were the most influential factors for prognosis.
