１９５２～１９９１年间共收治肾盂恶性肿瘤１７３例，占同期恶性肾肿瘤的３１．７％（１７３／５４６）。经手术治疗１６１例。男１１３例，女４８例。平均发病年龄５８岁。其中移行上皮癌１５１例（９３．８％）。肾盂癌的发病数逐年呈上升趋势，近４０年每１０年间年平均发病数分别为１．９，２．５，５．１及７．８例。１０７例（６６．５％）作了肾、输尿管全长及膀胱袖口式切除术。２５例（１６．０％）术后复发膀胱癌。术后３、５和１０年的生存率分别为７５．６１％（９３／１２３），６０、１９％（６５／１０８）和４５．３５％（３９／５６）。影响肾盂癌预后的主要因素是肿瘤的临床分期和病理学特征。
Between 1952 and 1991, 173 cases of renal pelvic malignancies were treated, accounting for 31.7% (173/546) of malignant renal tumors in the same period. After surgical treatment of 161 cases. 113 males and 48 females. The average age of onset was 58 years old. 151 cases of transitional cell carcinoma (93.8%). The incidence of renal pelvic cancer has been on an upward trend year after year, the average annual incidence of every 10 years in the past 40 years were 1.9, 2.5, 5.1 and 7.8 cases, respectively. 107 cases (66.5%) underwent kidney, ureter length and cuff cuff resection. Twenty-five patients (16.0%) had recurrent bladder cancer. The survival rates at 3, 5 and 10 years after operation were 75.61% (93/123), 60, 19% (65/108) and 45.35% (39/56), respectively. The main factors affecting the prognosis of renal pelvis cancer are the clinical staging and pathological features of the tumor.
