Renal dysfunction requiring dialysis
Differential Diagnosis
Acute tubular necrosis
Technical issues (urine leak, vascular thromboses from anastamotic misadventures, etc…)
Antibody mediated rejection, cellular rejection (rare)
Cortical necrosis
Transplant ultrasound with doppler interrogation
Exclude obstruction, assess for urine leak
Doppler’s assess flow, resistive indices
Renal Scan
Assess radioisotope uptake and excretion
Good uptake, no excretion….ATN
Delayed uptake, no excretion…Rejection, Severe ATN
Percutaneous transplant renal biopsy
<30% decline of Cr over 3 days
Differential diagnosis and evaluation basically the same as delayed graft function
Mid 1990’s, infections exceeded rejection as leading cause for hospital readmission.
Transplant recipients at increased risk for postoperative bacterial infections
Lymphocyte depleting induction regimens increased dramatically risk of CMV
Though uncommon, pneumocystis, other fungal infections potentially catastrophic
