Background. The aim of the work is to study the correlation of internal diameters of the segments constituting a dichotomy - a structural unit of the kidney intraorganic arterial bed.
Materials and methods. The authors conducted the morphometric study of the angiogrammes of kidneys of 8 men (16 organs) aged 36-60 years with no occlusion-stenotic lesions of the renal arteries. The parameters of 565 arterial dichotomies were studied.
Results. There were found 4 different structural types of dichotomies.
Conclusions. Supposedly, the structural features determine the differences of functions performed by the dichotomies. Morphofunctional principle of dichotomy optimality should be formulated according to the differences of the functional purpose of structurally-different types. The observed patterns of structure of kidney's arterial bed would be taken into account in its mathematical modeling.
