History and Physical Examination

Patients iwth contrast-induced nephropathy usually present with a history of contrast administration, 24-48 hours prior to presentation, during a diagnostic or therapeutic procedure (eg, percutaneous coronary intervention [PCI]). The acute kidney injury is usually nonoliguric.

A physical examination is useful for ruling out other causes of acute nephropathy, such as cholesterol emboli (characteristic findings of which include blue toe and livedo reticularis) or drug-induced interstitial nephritis (which typically involves a rash). Patients may have evidence of volume depletion or may be in decompensated heart failure. See DDx/Diagnostic Considerations.
