[Long-term survey of renal transplant preserved with Collins solution (author's transl)]

Collins solution is one of the world methods used for kidney preservation. A long term survey of transplanted kidneys thus preserved has never been reported. Clinical, biological, radiological and pathological data collected from 225 cadaver kidney tranplantations were analysed according to the total ischemic time (T.I.T) groupe I: TIT less than or equal to 12 hours, groupe II: TIT from 12 to 30 hours). No difference could be demonstrated between the two groups whether considering the percentage of immediate function, the serum creatinine level which was normal up to two years, the incidence of abnormal blood pressure, the pathological changes on routine biopsies performed at 6 months and 2 years and arteriographic features at 2 years. A better graft survival rate was consistently found at 6 months one year and 2 years when TIT was between 12 and 30 hours. This could be related to the higher indicence of well matched kidneys in this group of patients. The efficiency of exchange programs for compatible kidneys is thus emphasized.
