Diagnosis and treatment of patients with renal trauma.

In this selective study, 59% of the patients had a renal injury (laceration, rupture or pedicle injury). A normal IVU excluded significant renal injury after blunt trauma. Renal angiography was more accurate than ultrasonography or computed tomography in determining the extent of the injury. A retroperitoneal haematoma found during laparotomy should be explored if significant renal trauma cannot be excluded. Renal salvage after rupture or pedicle injury should be attempted in stable patients.
