Background: Renal transplant recipients may experience delayed graft function (DGF), but recovery can take many months, a condition we define as hyper-delayed graft function (HDGF). Methods: A retrospective review of 50 renal transplant recipients who had HDGF and comparison with patients who had immediate graft function (IGF) and DGF. Results: Acute renal tube necrosis (ATN) during or soon after surgery was the most common cause of HDGF. Following standard treatment, 48 HDGF patients transitioned from oliguria to polyuria in 45 days (± 3) and renal function of the kidney fully recovered in 73 days (± 1). These HDGF patients had similar overall survival and kidney survival rates as IGF and DGF patients who were matched for age, sex, primary underlying disease, tissue matching, warm and cold ischemia time, and surgery time. Conclusions: Appropriate care and monitoring of HDGF patients allows them to regain normal renal function and to achieve patient and renal survival rates similar to those of IGF and DGF patients.
