肾脏偶发占位病变的诊治体会

Incidental small spaceoccupying lesions of the kidney

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。

Objective To review and present the diagnosis and treatment of small spaceoccupying lesions of kidney less than 3cm in diameter. Methods 49 cases of small spaceoccupying lesions of kidney less than 3cm in diameter were reviewed. ResultsBZOf the 49 lesions,36 were detected incidentally on Bultrasonography and 13 on CT scanning.There were 31 cases of renal carcinoma,10 high density renal cyst,7 harmatoma of the kidney and 1 adenoma of the renal cortex.1 patient died after surgery for renal carcinoma.14 survived more than 5 years.In a case of renal harmatoma on follow up the tumor appeared to enlarge by 0.6cm. Conclusions The diagnosis of a small spaceoccupying lesion of the kidney incidentally found on Bultraconography,CT scanning or/and MRI should be made on careful analysis.When the preoperative diagnosis has been uncertain,pathological studies of the frozen sections should be carried out.
