title: Computed tomography evaluation of renal parenchymal volume in patients with chronic pyelonephritis and its relationship to glomerular filtration rate.
abstract: The measurement of renal parenchymal volume using a calibrated computed tomography image processing method has been evaluated clinically on a cohort of patients with chronic pyelonephritis. Comparison of renal volume with function as assessed by 99Tcm DTPA renography demonstrated a simple linear relationship in patients who were normotensive and aproteinuric. The implications of this result on the interpretation of prognostic factors determining declining renal function in chronic pyelonephritis are discussed.
