Abstract
Patients (37) with nonopaque pelvocalyceal filling defects on excretory urography, had intrapelvic masses on computed tomography (CT). There were 20 nonopaque stones, 14 cases of transitional-cell carcinoma, 1 benign papilloma and 2 blood clots. All had a sufficiently specific range of CT numbers and differences in contrast enhancement to allow the correct diagnosis on plain CT scans, or, if necessary, a dynamic CT study following a rapid i.v. bolus of contrast medium.This publication has 0 references indexed in Scilit:
