    Abstract:
    The paper is concerned with mathematical calculations of two methods to determine the amount of the functioning renal parenchyma using the polyposition statistic scintigraphy data. These methods are used to determine the depth of kidney location from the body surface in the lumbar region. An analysis of polyposition scintigraphy of 122 patients without tumor lesion has shown that in 41.7% of the cases the difference in the depth of location was over 1 cm. in 13.1% over 2 cm and in 5.7% over 3 cm. If one of the kidneys is shifted forward by 3 cm, in scintigraphy gamma-irradiation from this kidney for 99mTc will be weakened more than 1.5 times, and for 197Hg more than 1.75 times. It is only in renal insufficiency and in obese patients that the method of estimated RPD accumulation in the kidneys with regard to lateral projections is the best as compared to that using the results of scintigraphy of front and back projections.
