In order to assess the immediate renal function after HBD in our country, immediate diuresis was comparead in HBD and live donor (LD)recipients. We reviewed the recipient records of 112 HBD and 45 LD between January 2001 and August 2005. A check list was prepared for each patient asking many variables that might be relevent. After harvesting kidneys, we start irrigation immediately and then transplant them, so the cold ischemic time is less than 60 minutes. 112 HBD and 45 LD recipients included. The cold ischemia time was less than 1 hour in our method (in comparison with CIT>=24 hours in other countries. Nearly 99 (88.5%) recipients from HBD had like live donor immediate diuresis so BUN and creatinin decreased shortly afterward(s) by irrigating kidney in harvested room and transplant them in the nearby room (Iranian Model). This results is approximately like live donor immediate diuresis and much better regard to western model of HBD kidney transplantation.
