How to evaluate acute kidney injury in the kidney transplant patient?
Careful evaluation is mandatory when analyzing the baseline kidney function and assessing the serum creatinine (Scr).
The ideal baseline serum creatinine is based on the most recent trend whenever the patient was in a steady state.
The most critical parameter is the time after transplantation which helps in sorting through the differential diagnosis of acute kidney injury.
The most important differential changes when the patient is a recent transplant and could have surgical complications, such as a urine leak in the first few months as opposed to a patient who has undergone kidney transplantation for several years in whom the urine leak is less likely.
