Is Contrast Induced Nephropathy (CIN) Really Not a Thing?

September 25, 2017

Background: One of the most common imaging modalities used in the emergency department (ED) today is computed tomography (CT) scans using intravenous radiocontrast agents. Use of IV contrast can help increase visualization of pathology as compared to non-contrast CTs. However, many patients do not get IV contrast due to fear of contrast induced nephropathy.  Furthermore, […]

Background: The treatment of urinary retention is pretty straightforward; place either a Foley catheter or suprapubic catheter to decompress the bladder.  What is less clear, and more often debated, is if we need to clamp the catheter after 200 – 1000mLs of urine output or just allow complete drainage.  Historic teaching has been to do […]

Background: In patients with compromised renal function, the use of intravascular iodinated contrast material is generally not given to avoid contrast induced nephropathy (CIN). Currently, there is no treatment for contrast-induced nephropathy, therefore the focus has been on prevention. Guidelines recommend prophylactic prehydration in the prevention of CIN in high risk patients.  These recommendations are […]

Background: Use of contrast media in CT scans has been cited as one of the most common causes of iatrogenic acute kidney injury.  Its use however improves the diagnostic accuracy of CT scans.  Some studies have even reported an incidence of contrast induced nephropathy (CIN) as high as 14%.  Many of the studies coming to […]

Renal colic is a common ED presentation. Rarely does a day go by that we don’t see a patient rocking and rolling in acute renal colic. Dan Firestone makes an impassioned argument against the use of CT scanning for diagnosis of renal colic so I won’t address that here. Once we make a diagnosis, our […]
