Diuretic Radionuclide Urography: A Non-Invasive Method for Evaluating Nephroureteral Dilatation

Abstract

The diuretic radionuclide urogram is a simple, rapid and non-invasive technique to determine whether true obstruction exists in dilated nephroureteral systems. The methodology, results and interpretation of 102 studies in 41 patients are presented and compared to the conventional methods of assessing hydroureteronephrosis.
