[A clinical survey on malignant tumors of upper urinary tract in a 10-year period].

A clinical survey was done on 107 patients with malignant tumor of the upper urinary tract (50 renal tumors, 25 renal pelvic tumors, 32 ureteral tumors) treated at our Department during the last 10 years (1976-1985). All types of tumors occurred more frequently in males than in females. The age groups of patients in which renal, renal pelvic and ureteral tumors were seen most frequently were those in their sixties, sixties and seventies, respectively. The most frequent primary symptom in patients with these three tumors was gross hematuria. The 5-year actual survival rate for the patients with renal, renal pelvic and ureteral tumors was 48.1, 37.9 and 31.8%, respectively. For all 3 kinds of tumors, the prognosis of patients with high-grade and high-stage cancer was worse than that of patients with low-grade and low-stage cancer. One-hour erythrocyte sedimentation rate for all the tumor types, weight of resected kidney in the case of renal tumor, and the class of urinary cytology and drip infusion pyelography findings in the case of renal pelvic and ureteral tumors were considered to be the factors possible influencing prognosis.
