[A fractured kidney, an unexpected sequela of a remote lumbar trauma].

A 40-year old man is evaluated for arterial hypertension of one's year duration, which responded well to salt restriction and mild antihypertensive medication. The standard investigation for possible secondary hypertension is negative. In view of a remote history of left renal trauma, it is decided to do an angiogram, which reveals the presence of a fractured left kidney. This unusual image is considered to be secondary to the combination of an arterial supply provided by two polar arteries and of scarring in the mid-portion of the renal parenchyma secondary to the remote trauma.
