目的 提高对囊性肾癌的认识。 方法 对 1982～ 1997年收治的 15例囊性肾癌的临床特点、影像学、病理学特征及治疗预后情况进行回顾性分析。 结果 术前影像学检查提示囊肿相关肾占位性病变 12例 ,其中伴钙化 5例 ,单纯性囊肿 3例 ;术中活检发现癌变 2例 ,多房囊肿性肾癌 1例。 15例均行根治性肾切除术。 13例获随访 ,存活时间 3个月～ 8年 ,平均 3.2年。 结论 囊性肾癌有其独特的临床、影像及病理学特征 ,对不符合典型单纯性肾囊肿性病变应考虑存在囊性肾癌的可能。
Objective To raise awareness of cystic renal cell carcinoma. Methods The clinical features, imaging features, pathological features and prognosis of 15 cases of cystic renal cell carcinoma admitted from 1982 to 1997 were analyzed retrospectively. Results Preoperative imaging examination revealed cyst-related kidney lesions in 12 cases, including calcification in 5 cases and simple cysts in 3 cases. Intraoperative biopsy showed 2 cases of canceration and 1 case of multilocular cystic renal cell carcinoma. All patients underwent radical nephrectomy. Thirteen patients were followed up for 3 months to 8 years with an average of 3.2 years. Conclusion Cystic renal cell carcinoma has its own unique clinical, imaging and pathological features, cystic renal cell carcinoma may be considered in cases of non-coincidental simple renal cystic lesions.
