目的 提高对囊性肾癌的认识。方法 对 11例囊性肾癌的临床、超声和CT特点 ,以及病理学特征、手术方式和预后进行回顾性分析。结果 11例中行根治性肾切除 10例 ,肾部分切除 1例 ,术后病理均为囊性肾透明细胞癌 ,9例获随访 5～ 13 2个月 ,无肿瘤转移和复发。结论 CT在囊性肾癌的术前诊断中是一种有价值的常用检查方法。对术前怀疑囊性肾癌者 ,术中需做病理检查 ,确诊者宜行根治性肾切除或肾部分切除。熟悉囊性肾癌的病理学和影像学特征是提高诊断准确率的关键。囊性肾癌预后良好。
Objective To raise awareness of cystic renal cell carcinoma. Methods The clinical features, ultrasonography and CT features of 11 cases of cystic renal cell carcinoma were analyzed retrospectively. The pathological features, operation methods and prognosis were retrospectively analyzed. Results Of the 11 cases, 10 cases were radical nephrectomy and 1 case was partial nephrectomy. All cases were cystic renal clear cell carcinoma and 9 cases were followed up for 5 to 132 months without tumor metastasis and recurrence. Conclusion CT is a valuable and commonly used method in the preoperative diagnosis of cystic renal cell carcinoma. Preoperative suspected cystic renal cell carcinoma, intraoperative need to do pathological examination, diagnosed with radical nephrectomy or partial nephrectomy. Familiar with the pathological and imaging features of cystic renal cell carcinoma is the key to improve the diagnostic accuracy. Cystic renal cell carcinoma has a good prognosis.
