Objective: To get basic knowledge of a type and extent of renal tissue injury in traumas of lower stage describing macroscopic changes in correlation with USG investigation. Materials and methods: fresh kidneys of the pig (Sus strofa f. domestica) used for experimental trauma defined by the falling speed of 5 m/s with macroscopic and USG investigation of posttraumatic changes. Results: Macroscopically multiple ruptures of parenchyma were confirmed that were not in spatial correlation with less ruptures of capsule. Injury of the hollow system was not manifested. USG investigation revealed best the presence of extravasate, in detection of smaller ruptures it is less successful. Rupture at the same level as the signal of the sensor might not be scanned. Conclusion: The trial brought the knowledge of traumatic changes of the lower stages in renal tissue from the view of macroscopic surveillance and limited the possibility of USG detection of these changes. It also revealed the use of further methods in detecting changes.
