Microdialysis Sampling of Renal Interstitial Fluid in Acute Studies

The microdialysis technique has been applied extensively during the last three decades where most of the research has focused primarily on the site of action. The microdialysis probe was developed for collection of interstitial fluid as well as delivering drugs to the target site. In comparison with other methods, the microdialysis technique has delivered more accurate results with minimal invasive procedures. Initially, the microdialysis technique was designed to quantitate dopamine levels in cerebral tissues, which facilitated the applications of this technology as a sampling tool. Presently the microdialysis technique has been applied to various organs such as the heart, kidney, and liver. In the current report, we describe the principle of the microdialysis technique and its application in in-vivo studies. Specifically, the present review provides the adaptation of this method in renal acute studies. However, the rationale for this report is to demonstrate that the microdialysis technique can be used to collect renal interstitial fluid in real time with no effect on the hemodynamic function.
