BACKGROUND In the past, the majority of renal transplantations in Iran were from living donors, but recently cadaveric donation of organs is increasing. We reviewed our experience on kidney transplantation from cadaveric donors for the past 5 years in our center. METHODS Between July 1998 and September 2004, 122 kidneys were removed from 61 cases of brain-dead patients and transplanted in 114 patients with end-stage renal disease in our center. Two kidneys had tumoral involvement and were discarded. Three kidneys were transplanted in other centers and three patients received en bloc kidney transplantations. In addition, we performed nine cases of heart, one case of liver, and one case of lung transplantations. All the recipients were followed for at least 1 year and posttreatment renal function and graft survival were determined. RESULTS All cadaveric donors were brain dead due to car (30%) and motocycle (70%) accidents, with ages ranging from 5 to 56 years (mean, 24/4 years). The mean warm and total cold ischemia times were 7 minutes and 8.1 hours, respectively. The mean distance between harvesting center and our hospital was 65 km. The 1-year graft survival was 92.3%, with mean serum creatinine of 1.76 +/- 0.79 at 1 year. Of other transplanted organs, the liver and lung recipients died 24 hours and 45 days after operation. Among heart recipients, four are still alive. CONCLUSIONS Cadaveric donors in developing countries including Iran can be excellent sources of organ donation.
