Abstract
The aim of the study was to verify whether ultrasonography can be considered a reliable method for the diagnosis of low-grade renal trauma. The results of this study demonstrated that the validity of ultrasonography for the diagnosis of low-grade renal injury is not significant, because this examination can reveal only some of the renal injuries such as perirenal haematoma.
An injury to the renal parenchyma is also indicated by hypoechogenic areas of varying sizes in the renal cortex. A negative ultrasonographic finding is no proof of the absence of renal trauma.
As low-grade renal injury is difficult to detect by mere clinical examination or by a single imaging method, the authors regard as necessary to actively look for them, taking into consideration the mechanism of injury, haematuria findings and evaluation of ultrasonographic and CT scans.
