Abstract
Renal bacterial infection spans a continuum of severity from uncomplicated acute pyelonephritis to frank abscess formation. It can be a multi-focal process, with different portions of the kidney exhibiting different degrees of inflammation. The radiologic diagnosis of acute renal infections is based upon IVU, US and CT. In this investigation, the contribution of IVU, US and CT is evaluated in 3 patients with acute multifocal pyelonephritis and renal abscesses. The lack of specificity of IVU and the high false negative rate of US make them unsatisfactory diagnostic tools for patients clinically suspected of having multifocal pyelonephritis or renal abscess. CT is more sensitive for the detection of acute renal inflammatory diseases and for defining the extent of disease, thereby helping programme early and accurate therapy.
