Abstract
The aim of the investigation was to present the results of dynamic ultrasound examination of the evolution of local changes accompanying kidney injury in comparison with the studied manifestations of pathomorphogenesis of renal injury. Dynamic ultrasound examination of 216 patients aged 2 to 16 years with kidney injury of varying severity was performed. The obtained data were compared with the results of X-ray examinations, intraoperative findings and pathomorphological conclusions. It was showed that polymorphic changes accompanying a renal injury can be differentiated based on the identification of specific morphodynamic stereotypes – permanent evolving signs that accompany, in particular: bruising (contusion) of the kidney, tissue integrity disorders, hemorrhagic manifestations, intra-organ vascular obstruction and acute post-traumatic inflammation. Each of the presented stereotypes is comparable with the corresponding manifestations of pathomorphogenesis of traumatic damage to the renal tissue. Conclusion. Echographic data, clearly correlated with changes in the morphological substrate, determine the ultrasound semiotics of kidney injury. This allows us to identify and predict the development of each stereotype in a timely manner, with the selection of the dominant (clinically most significant) at the time of the study, which in due time can be used for a rational choice of organ-preserving treatment tactics.
