Page kidney

Page kidney refers to the phenomenon of hypertension that develops following long-standing compression of renal parenchyma by subcapsular renal collection, e.g. haematoma, seroma, urinoma.

Compression of the renal parenchyma results in compression of the renal vessels, which leads to decreased blood flow and activation of the renin-angiotensin system. The renin-angiotensin system activation results in a rise in blood pressure and where this is prolonged, hypertension. 

All modalities will demonstrate a collection surrounding the kidney, of variable density / intensity / echogenicity depending on the nature of the collection. Importantly, the adjacent renal parenchyma should be distorted. 

This phenomenon was first described by Irvine H Page in 1939 2 when he discovered that hypertension could be produced in a dog by wrapping one or both kidneys in cellophane.
