Posttransplant acute renal failure

Acute renal failure posttransplant is a multifactorial syndrome in the early phases of transplantation. Delayed graft function is common and confers an adverse prognosis for both short- and long-term survival of the renal allograft. Later out from transplantation, the differential diagnosis of acute renal failure is usually between acute renal failure secondary to rejection or cyclosporine nephrotoxicity. Transplant biopsies are often needed to distinguish these possibilities.
