Clinical observation and prognostic factors of renal pelvic tumor / 대한비뇨기과학회지

We reviewed 28 patients with renal pelvic tumor during the period from 1974 to 1989 and 17 patients were followed up. The over all survival rate at l, 2, and 3 years was 88%, 63%, and 50%, respectively, by the Kaplan-Meier method. The stage and the grade of the tumor were the most influencing factors on prognosis. Simultaneous tumors of ureter or bladder, non-visualizing kidney on excretory urography, duration of the gross hematuria more than 6 months showed relatively poor prognosis. But development of subsequent bladder tumor did not seem to influence on prognosis.
