Modelos experimentales en nefrología. Modelo de riñón aislado y perfundido

Abstract

El modelo de riñón aislado y prefundido brinda la posibilidad de analizar la función renal bajo condiciones definidas y sin la intervención de factores sistémicos. Este modelo consiste en aislar al riñón de la vasculatura sistémica, y perfundirlo a través de la arteria renal con un medio de perfusión con características similares al plasma o a la sangre, conservando las características anatómicas, bioquímicas y funcionales del riñón intacto. Esto posibilita circunscribir factores extrarrenales que pueden complicar la interpretación de la información obtenida con experimentos realizados in vivo. Además, la utilización del órgano aislado permite el estudio de la función renal bajo condiciones en las que el operador puede modificar las variables a analizar de manera controlada. En el presente artículo se revisa la técnica de preparación, los criterios de viabilidad, las principales características hemodinámicas y tubulares, y las aplicaciones del modelo.

The isolated perfused kidney model provides the ability to analyze the renal function under defined conditions without the intervention of systemic factors. In this model, the kidney is isolated from the systemic vasculature, and infused through the renal artery with a perfusion medium with the plasma or blood characteristics. The anatomical, biochemical and functional characteristics of the intact kidney is preserved. This allows to circumscribe extrarenal factors that can complicate the interpretation of the in vivo experiments. Moreover, the use of the isolated organ allows the study of renal function under conditions in which the operator can modify the analyzed variables in a controlled manner. In this article, the technique of preparation, viability criteria; and the main hemodynamic and tubular features and applications of the model are reviewed.
