小肾癌54例诊治分析

目的 提高小肾癌的诊断水平和治疗效果。方法 对54例直径小于3cm的小肾癌的诊断与治疗进行回顾性分析。结果 54例中因体检或其他疾病检查时发现者37例（68．5％）；腰痛9例（16．7％）；血尿5例（0．9％）；腰痛伴血尿3例。行根治性肾切除术43例．行保留肾单位手术11例。术后均经病理证实。术中快速冰冻切片证实5例。结论 小肾癌多为偶然发现。其早期诊断主要依靠B超、CT、MRI和DSA等影像学检查；手术视具体情况行根治性肾切除术或保留肾单位手术；小肾癌病理分期低。肿瘤体积小．预后较好，生存率高。

Small renal cell carcinoma: report of 54 cases

Objective To improve the diagnosis and treatment of small renal cell carcinoma.Methods 54 cases of small cell carcinoma less than 3cm in diameter were reviewed.Results 37 patients(68.5%) were asymtomatic while 9((16.7%)) complained of lumbago and 5(0.9%) nematuria.43 patients were treated with radical nephrectomy,11with nephron sparing surgery.All carcinomas were confirmed after operation.Conclusion Small renal cell carcinoma are often discovered accidentally.The early diagnosis mainly depends on imaging examination,such as B-ultrasound,CT scan,MRI and DSA.Radical nephrectomy or nephron sparing surgery should be performed according to different situations.Small renal cell carcinoma has lower clinical stage.The smaller the size,the better the prognosis and the higher the survival rate.
