[Possibilities for the use of sonography in kidney injuries]

As a non-invasive, easily repeatable examination ultrasound can supplement or even replace angiography in cases of renal trauma. Since it is moreover cheap and quickly performable, an ultrasound examination should never be omitted when renal trauma is suspected. It does not matter whether it is performed before or after infusion urography; this will mainly depend on the facilities available. It must be stressed that ultrasound is diagnostic tool and that its full potential is only realized in combination with other diagnostic methods, e.g. urography, angiography, computerized tomography.
