海绵肾影像诊断(附4例报告及文献复习)

The Imaging Diagnosis of Spongiform Kidney (Four Cases Report and Review the Literature)

目的：结合文献探讨海绵肾影像学检查的诊断价值。材料和方法：回顾性分析了４例海绵肾的Ｂ超、Ｘ线平片及静脉尿路造影表现。结果：本组４例全部做过Ｂ超检查，其中２例做了Ｘ线平片及静脉尿路造影。Ｂ超表现为肾髓质锥体部集合小管的小囊样扩张和／或囊腔内的强回声光点。Ｘ线平片，仅见双肾实质内呈簇状排列的致密微结石影，如绽开的礼花样。静脉尿路造影片见肾锥体内呈扇形、密丛状或葡萄串状扩张的集合小管。结论：Ｂ超、Ｘ线平片、静脉尿路造影对海绵肾均有较高的诊断价值，Ｂ超简便易行，可作首选，当Ｂ超疑有海绵肾时，应做Ｘ线平片和静脉尿路造影进行对照分析。

Purpose:To explore the diagnostic value of the imaging examination of spongiform kidney combined with the literature.Materials and Methods:The manifectations of Bmode US,Xray plain film and IVP of 4 cases of spongiform kidney were analysed retrospectively.Results:In this group,4 were performed by US,2 were performed by Xray plain film and IVP,US:In the renal medullary pyramidal collecting tubules,its display as a little saclike dilatation and/or highecho spots on the sac cavity.On Xray plain film,one case appeared as crowded density microstones shadow,like “dropping lily”.The urinarygraphy,the renal intrapyramid display fan shape,a cluster of grapelike dilatation of collecting tubules.Conclusion:The US,Xray plain film and intravenous Fyelography possess diagnostic values highly,the US is performed easy and simple,it may be selected first,when spongiform kidney is suspected,the Xray plain film and urinarygraphy would be performed for the control analysis.
