Abstract:

One aspect of the research involves the conceptualization of a renal hemodynamic model which would provide a method for determining instantaneous impedance changes in the kidney. By analysis of wave shape and amplitude of renal blood pressure and flow it is feasible to estimate vascular resistance changes occurring in the kidney. Furthermore, these impedance relationships provide an indicator of change in renal hemodynamics which is more revealing than the overall pressure and flow responses. A second aspect of the research efforts involves the use of the renal model and totally implanted telemetry to measure renal responses. On the basis of the model being developed and the data obtained when the subjects were stressed it appears that direct neurogenic effect on the preglomerular resistance if present was neutralized but a hormonal influence was exerted on the postglomerular resistance.
