title: Imaging techniques and renal infections.
abstract: Newer techniques have supplanted the urogram as the preferred procedure for evaluation of several renal infections. When imaging is indicated in acute pyelonephritis, sonography should be performed first. In focal pyelonephritis, sonography and/or computed tomography are preferred. These techniques are also generally required for elucidation of renal abscess and pyonephrosis.
