Identifiable causes of AKI. A pre-renal aetiology (such as hypovolaemic shock) was identified in 55.1%, sepsis in 40.6% and rhabdomyolysis, usually related to trauma, in 24.8%. “Other” included obstructive uropathy, direct drug nephrotoxicity, hypertensive crisis, thrombotic microangiopathy, and rapidly progressive glomerulonephritis. More than one cause may have been implicated in the same patient, especially if the patient developed more than one episode of AKI during the same admission
