LLEDO GARCIA, E. et al. Normothermic ischemia effects in renal microcirculation. Actas Urol Esp [online]. 2005, vol.29, n.8, pp.739-742. ISSN 0210-4806.

We report the results obtained in a experimental work designed to evaluate the consequences of warm ischemia in hypothermic isolated renal perfusion. We perfused a number of kidneys after a period of 45 min of vascular occlusion. An alternative group of kidneys were perfused without previous warm ischemia. Ureter was canulated in all the procedures and output collected during the HP. Creatinine was added to the perfusion solution initially in order to determine creatinine clearance. HP hydrodynamics was recorded on real time through a computerised system. According to the results, renal vascular resistance as well as CrCl were higher in ischemic kidneys. Both facts along with minimal differences in pathologic study suggest an increase in vascular tone of efferent-postglomerular arteriole during HP. HP was an adequate technique to minimize histologic consequences of ischemia. Mycrovascular an biochemical changes produced during HP may be produced, essentially, by dynamic causes.
