自发性肾破裂的影像学诊断(附24例报告)

Imaging evaluation of spontaneous rupture of kidney (report of 24 cases)

分析自发性肾破裂致肾包膜下和肾周出血的ＣＴ与选择性肾动脉造影（ＤＳＡ）表现，以发现肾破裂病因方面的诊断价值。回顾分析２４例自发性肾破裂伴肾周出血病人，全部经ＣＴ检查，３例行ＤＳＡ检查并栓塞治疗。结果２４例自发肾破裂中１９例为肾肿瘤（７９％），其中１２例肾血管平滑肌脂肪瘤（５０％），７例肾细胞癌（２９％）。认为ＣＴ是诊断急性自发性肾破裂出血最有价值的检查方法，其病因诊断率可达９０％；而ＤＳＡ在寻找血管性病变致肾破裂病因方面优于ＣＴ，并可行栓塞治疗。自发性肾破裂出血常见原因是肾肿瘤。

CT( n =24) and DSA ( n =3) have been conducted for 24 cases of spontaneous rupture of kidney with perirenal hematoma.Renal tumor was found in 19 (≥9%),of which 12 being agiomyolipoma.It was concluded that CT is the most valuable examination in the diagnosis and evaluation of spontaneous rupture of kidney and DSA is helpful in the evaluation of vascular diseases.It was pointed out that angiomyolipoma has been the most common cause of spontaneous rupture of kidney with perirenal hemorrage.
