Page kidney is a condition caused by a subcapsular collection compressing the kidney and typically presenting with flank pain and hypertension. Compression of the renal vasculature leads to activation of the renin angiotensin system.

The frequency with which hypertension occurs after renal trauma has been the source of much debate. Reported rates range from 0% to 55% (4,8,19–21). Unfortunately, with the poor follow-up of trauma patients there are few studies that look at this issue. Given the high background prevalence of hypertension, those studies that have been performed are likely underpowered to answer this question. Still, there are several reports of new onset hypertension in young, otherwise healthy patients after renal trauma. One study with four years of follow-up suggests that there is a higher incidence in nonoperatively managed patients; (20) however, others have not been able to reproduce this finding. The etiology of hypertension may include renal artery stenosis after injury (21,22) or extrinsic compression of the kidney either acutely from hematoma or chronically from scar (Page kidney) (23,24). A final possible cause is an arteriovenous fistula, which, like renal artery stenosis and Page kidney, leads to renal underperfusion and consequent hyperreninemia.

Page kidney occurs due to extrinsic compression of the renal parenchyma by a mass or hematoma, leading to activation of the renin-angiotensin-aldosterone system, causing secondary hypertension.1 Common causes are renal tumors including angiomyolipoma, trauma especially from sports, motor vehicle accidents, iatrogenic causes, anticoagulation, polyarteritis nodosa, operative, and idiopathic.2 Renal angiomyolipomas (RAMLs) are the most common benign tumors of the kidneys. The most common and life-threatening complication of angiomyolipoma is rupture and subsequent hemorrhage.3
