Ever increasing evidence exists that the tubuloglomerular feedback system exerts a major influence on overall renal function. Several examples are potentially pertinent to clinical medicine in which there is reasonable evidence that activation or suppression of tubuloglomerular feedback mechanisms contribute significantly to alterations in normal renal physiology. However, in most examples reported, the feedback mechanism is one of several influences acting in concert to determine the final nephron filtration rate, its respective determinants, and the relationship of filtration to the rate of tubular reabsorption. A more complete understanding of all the factors which influence and modify the functional role of tubuloglomerular feedback mechanisms will aid our understanding significantly and the consequent therapy of a variety of altered physiologic conditions.
