Usage of histological methods in determining the prescription of kidney injuries in forensic medical practice

Introduction: The article presents data from literary sources and a statistical analysis of our own research on the nature, mechanism and prescription of kidneys injury in case of mechanical trauma and the absence of alcohol intoxication. The aim: To study the dynamics of changes in the histological parameters of the kidneys injured tissues in case of mechanical trauma depending on the prescription of injury.

Materials and methods: The material of the study was the kidneys tissue of 48 males and females aged from 20-60 who died at known and unknown time in the presence and absence of alcohol in the blood. We used histological, histochemical methods, and carried out the analysis of results.

Results: The obtained results showed that during the mechanical injury of kidneys there often developed a capsule and a parenchyma with hematoma in the area of injury. Our records showed that during the first 6 hours after injury, there appeared a hematoma in the center of the injury. Hemolysis of the erythrocyte particles was observed in the center of the hematoma. There were also isolated leukocytes and fibrin tissues closer to the edge of the hematoma.

Conclusions: The obtained results indicate that there are several histological changes in the damaged kidneys tissues area which directly depend on the time which passed from the moment of injury.
