Spontaneous subcapsular or perinephric hematoma in the absence of anticoagulation, arteritis or trauma is most likely due to an underlying renal tumor. Eight such patients recently have been evaluated and after nephrectomy 5 had small tumors undetectable by imaging techniques, including computerized tomography or angiography. In 1 patient a tumor was demonstrated preoperatively by angiography and in only 2 was a tumor not found. In the absence of an apparent etiology, patients with spontaneous renal bleeding and a normal contralateral kidney should undergo radical nephrectomy because of the extremely high incidence of small undetectable occult tumors, often less than 2 cm. in size.
在没有抗凝、动脉炎或外伤的情况下，自发性肾包膜下或肾周血肿最可能是由潜在的肾肿瘤引起的。最近对8例此类患者进行了评估，肾切除术后，5例患者有影像学技术（包括计算机断层扫描或血管造影）无法检测到的小肿瘤。1例患者术前通过血管造影显示有肿瘤，只有2例未发现肿瘤。在没有明显病因的情况下，由于小的隐匿性肿瘤（通常小于2厘米）的发生率极高，患有自发性肾出血且对侧肾脏正常的患者应接受根治性肾切除术。
