We examined the renal function in 18 brain dead patients 2-0 h before removing the kidneys and 72 h after their transplantation to the recipient. The kidneys were preserved by simple hypothermia. In brain dead patients we found no demonstrable relationships between PCr and CCr or between Purea and CCr. At this time the Purea and PCr values are not a sufficiently accurate indicator of renal function. We also examined the plasma and urinary concentrations of Na, K, urea and osmotically active substances and calculated their excretion fractions. We found that, prior to removal, the kidneys were in a state of combined osmotic and water diuresis. The osmotic diuresis was chiefly of a non-sodium type and was produced by a mannitol load. Water diuresis was evidently caused by inhibition of ADH output consequent to brain hypoxia. We also investigated the relationship between the CCr values before nephrectomy and in the early posttransplantation phase. We found that there was a relationship between the recipient's CCr values in the early posttransplantation period and donor's CCr/total ischaemic time index. Calculation of this index can be valuable, especially in high risk transplantations.

BACKGROUND: Hyperchloremia produces renal vasoconstriction and fall in glomerular filtration rate. In 90% of brain-dead organ donors, diabetes insipidus develops, characterized by inappropriate diuresis, hyperosmolality, and hyperchloremia. The aim of this study was to determine the relationship between the serum concentration of chlorides of the donor and the onset of the function of the kidney allograft in the recipient. METHODS: We retrospectively studied 213 donors and kidney allograft recipients. Serum creatinine concentrations and glomerular filtration rates on the 1st, 7th, and 30th days after transplantation of the recipients from hyperchloremic donors were compared with the recipients from normochloremic donors, as well as the incidences of acute tubular necrosis and delayed graft function. RESULTS: On the 1st day, serum creatinine concentrations of the recipients from hyperchloremic and normochloremic donors, respectively, were 448.2 ± 212.1 μmol/L and 502.2 ± 197.8 μmol/L (P = .1), on the 7th day, 168.6 ± 102.6 μmol/L and 196.9 ± 120.6 μmol/L (P = .13), and on the 30th day, 129.4 ± 43.3 μmol/L and 131.8 ± 43.6 μmol/L (P = .73). The differences were statistically significant. The groups also did not differ significantly in glomerular filtration rates and incidences of acute tubular necrosis and delayed graft function. CONCLUSIONS: In this study, no significant correlation between serum chloride concentrations of the organ donors and the onset of the function of kidney allografts in the recipients was found.
