    Abstract:
    The renal blood circulation was studied in 17 children aged 3 to 14 using a method of adaptive simulation of the organ blood flow. The main condition for radiorenoangiography is to place correctly a gamma-chamber of the heart, lungs and kidneys in the field of vision of the crystal. It is a requisite condition for the calculation of absolute and relative renal perfusion depending on the cardiac ejection. If a patient's body size does not make it possible to have the heart and kidneys in the field of vision of the collimator at a time, one can choose the spleen as the "model" organ. The analysis of angiographic results has shown that the share of the cardiac ejection which is responsible for the renal circulation and organ function respectively, is quite a stable value that is not associated with a patient's age and body mass. Irrespective of the state of the central hemodynamics and a patient's age, the most objective information on renal perfusion proceeds from an analysis of relative indices (or perfusion indices) that are calculated on the basis of the cardiac ejection expressed in percentage (or another model organ).
