【摘要】 目的 提高小于3.0cm偶发性肾脏占位病变的诊治效果。 方法 对49例肾脏偶发占位病变的诊治进行回顾性总结。 结果 B超检查发现36例，CT检查发现13例。肾癌31例，高密度肾囊肿10例，肾错构瘤7例，肾皮质腺瘤1例。肾癌术后死亡1例，生存超过5年者14例，1例肾错构瘤随诊肿瘤增大0.6cm,余未见异常。 结论 肾脏偶发占位病变应根据B超、CT、MRI综合分析作出诊断，定性不明者应行术中冰冻病检。

【Abstract】 Objective To reviewand present the diagnosis and treatment of small space-occupying lesions of kidney lessthan 3cm in diameter. Methods 49 cases of small space-occupying lesions of kidney less than 3cmin diameter were reviewed. Results Of the 49 lesions,36 were detected incidentally on B-ultrasonography and 13 on CT scanning.There were 31 cases of renal carcinoma,10 highdensity renal cyst,7 harmatoma of the kidney and 1 adenoma of the renal cortex.1 patientdied after surgery for renal carcinoma.14 survived more than 5 years.In a case of renalharmatoma on follow up the tumor appeared to enlarge by 0.6cm. Conclusions Thediagnosis of a small space-occupying lesion of the kidney incidentally found on B-ultraconography,CT scanning or/and MRI should be made on careful analysis.When thepreoperative diagnosis has been uncertain,pathological studies of the frozen sectionsshould be carried out.
