title: Diuresis urography in equivocal pelvi-ureteric obstruction.
abstract: In 43 patients with equivocal pelvi-ureteric obstruction, conventional urography was supplemented with diuresis urography. After peroral hydration with 0.5 liters fluid, a large volume of urographic contrast medium was administered and increased diuresis provoked by intravenous injection of furosemide. A relative obstruction of flow was then accentuated by increased dilatation of the renal pelvis. The technique deserves a wider use in the radiologic investigation of patients with equivocal obstruction at the pelvi-ureteric junction.
