目的 :提高肾盂肿瘤的诊治水平。方法 :回顾性总结 1983 - 1999年手术和病理证实的原发性肾盂移行细胞癌 14例 ,对其临床特点及各种检查方法的选择进行分析 ,并对其误诊原因进行讨论。结果 :术前明确诊断 12例 ,为 85 71%。 14例病理检查证实为肾盂移行细胞乳头状细胞癌 ,其中G1级 2例 ,G2 级 9例 ,G3 级 3例 ;Ⅰ期 3例 ,Ⅱ期 7例 ,Ⅲ期 2例 ,Ⅳ期 2例。得到随访 12例 ,无瘤生存 11个月～ 14a。结论 :血尿、腰痛和肾积水是肾盂癌主要临床表现。术前联合应用IVU、B超、逆行造影、CT、膀胱镜和尿脱落细胞学等检查可提高肾盂癌的正确诊断率。根治性肾、输尿管膀胱袖口样切除术是治疗肾盂癌的有效方法
Objective: To improve the diagnosis and treatment of renal pelvis tumors. Methods: A retrospective review of 14 cases of primary renal pelvis transitional cell carcinoma confirmed by operation and pathology from 1983 to 1999 was conducted. The clinical features and the selection of various examination methods were analyzed. The causes of misdiagnosis were discussed. Results: Preoperative clear diagnosis of 12 cases, 85 71%. Fourteen cases were confirmed as papillary transitional cell renal cell carcinoma. There were 2 cases of G1, 9 cases of G2 and 3 cases of G3. There were 3 cases of stage Ⅰ, 7 cases of stage Ⅱ, 2 cases of stage Ⅲ and 2 cases of stage Ⅳ. Were followed up in 12 cases, free survival 11 months ~ 14a. Conclusion: Hematuria, back pain and hydronephrosis are the main clinical manifestations of renal pelvic cancer. Preoperative combination of IVU, B ultrasound, retrograde angiography, CT, cystoscopy and urinary cytology and other tests can improve the correct diagnosis of renal pelvic cancer. Radical renal, ureterocele cuff resection is an effective treatment of renal pelvic cancer
