Due to multiple reasons, acute renal failure (ARF) commonly develops in the early postoperative period of orthotopic liver transplantation (OLT) recipients. The records of OLT recipients between 1999 and 2004 were evaluated. Age, gender, primary disease, history of diabetes, immunosuppressive drugs, pre- and postoperative renal function tests, serum electrolytes, dialysis, liver functions tests, and renal function tests in follow-up period were noted. We followed 16 patients with OLT in our center. ARF developed in 8 patients. Dialysis was per-formed in only 2 patients, and other patients with ARF were managed with conservative measures. Hypertensive crisis and cerebrovascular stroke developed in I diabetic hypertensive patient.
