探索肾盂恶性肿瘤的发病率，诊断和治疗的方法，以及影响预后因素。回顾性总结1975年至1995年我院收治的37例肾盂恶性肿瘤，并进行分析讨论。本组37例，占同期肾脏恶性肿瘤17％，94．5％血尿为首发症状。多灶性占32．4％，尿找瘤细胞阳性率为55％，IVP检查诊断率为75％，逆行造影诊断率为80％，B超诊断符合率77．8％。Ⅰ期9例，Ⅱ期19例，Ⅲ期9例。随访率89．2％，5年生存率50％。肾盂恶性肿瘤的诊断以血尿为主要线索，以IVP和B超为主要检查方法；早期诊断，坚持标准手术方式，探索辅助治疗方法，为提高生存率的必要条件。
To explore the incidence of renal pelvic cancer, diagnosis and treatment methods, and prognostic factors. Retrospective review of 1975 to 1995 admitted to our hospital 37 cases of renal pelvis malignancy, and analysis and discussion. The group of 37 cases, accounting for the same period, 17% of renal malignancies, 94.5% hematuria as the first symptom. The prevalence of malignant tumor was 55%, the diagnostic rate of IVP was 75%, the diagnostic rate of retrograde angiography was 80%, and that of B ultrasound was 77.8%. 9 cases of stage Ⅰ, 19 cases of stage Ⅱ, 9 cases of stage Ⅲ. Follow-up rate 89.2%, 5-year survival rate of 50%. The diagnosis of renal pelvic malignancies as the main clues to hematuria, IVP and B-as the main method of examination; early diagnosis, adhere to standard surgical methods to explore adjuvant therapy, to improve the survival rate of the necessary conditions.
