The presence of delayed graft function (DGF) was defined as the need for dialysis within the first week after surgery and/or failure of creatinine clearance to rise above 10 mL/min within the first 5 postoperative days irrespective of dialysis need, acute rejection, and immunosuppressant regimen at discharge.
Any complication or need for intervention following surgery was noted. Postoperative complications were rated according to the Clavien-Dindo classification [12 (link)].
Follow-up data were collected by our transplant program in cooperation with the Department of Nephrology of the University of Essen, Germany. Initially, patients were evaluated every 2 weeks until 3 months and every month thereafter until 6 months. After 6 months, the follow-up examination carried out every 3 months.
