title: An unusual vascular impression on the renal pelvis.
abstract: In a female patient who presented with the complaint of dysuria, angiography was required to distinguish a vascular impression on the renal pelvis from a possible tumor or calculus. Neither intravenous urography nor retrograde pyelogram clarified the smooth filling defect sufficiently to rule out the possibility of a urothelial tumor.
