Nephrologists are trying to catch up with the cardiologist. We are in the midst for a search for a troponin for kidney injury and this is important. several markers are being studied but none really validated and ready for clinical use yet.
What do we really need: How can we suspect renal injury early enough to trigger biomarker testing and more aggressive renal monitoring?
They suggest an angina equivalent for kidney injury....
What is that?
Oliguria, fluid overload and small changes in crt being renal angina equivalents. If these occur in an ICU patient, a more aggressive monitoring should be employed: urine chemistries, more frequent crt monitoring, cystatin C testing and perhaps an early renal consultation
