Ft. Hammad et al., Intra- and post-operative assessment of renal cortical perfusion by laser Doppler flowmetry in renal transplantation in the rat, EUR SURG RE, 32(5), 2000, pp. 284-288
Renal blood flow (RBF) in the period immediately following transplantation
has an important prognostic value. Here we report for the fi rst time on th
e use of laser Doppler flowmetry (LDF) for the measurement of renal cortica
l perfusion (RCP) during all the important steps in renal transplantation.
Left orthotopic kidney transplantation was performed in Lewis rats (n = 14)
after 2 h of cold ischaemia and preservation in EuroCollins solution. Unde
r baseline conditions, RCP in the donor and recipient kidneys were similar
with a coefficient of variability of 11 and 12%, respectively. There was a
progressive increase in RCP during the first 60 min after transplantation w
ith a return to normal values 2 weeks later. In conclusion, LDF provides a
rapid and continuous measure of RCP without interference to the operative s
ite and may prove a useful tool for the measurement of RBF during kidney tr
ansplantation. Copyright (C) 2000 S. Karger AG,Basel.
