[Canine kidney preservation by intermittent perfusion with hypothermic Collins- or Sacks-solution (author's transl)]

37 canine kidneys were intermittently perfused with Collins- or Sacks-solution every 2--6 h. 32 of these kidneys were transplanted after 12--24 h storage time. Additionally, 24 kidneys were stored under hypothermia for 12--24 h and then transplanted (control group). During perfusion the oxygen consumption of the kidneys and the enzyme and lactate release were measured. It was impossible to improve the results of hypothermic storage preservation by intermittent perfusion of the kidneys, on the contrary kidney function deteriorated by the number of perfusion processes. The failure of intermittent perfusion is caused by the increase of renal vascular resistance during perfusion. From the oxygen consumption and lactate release measurement it was concluded, that the washout solutions for kidney preservation should contain more substrate which can be utilized under anaerobic conditions to improve the results of hypothermic storage preservation.
