title: Obliterative pyelitis.
abstract: A patient with severe undiagnosed and untreated pyelitis developed mural masses in the renal pelvis and in the infundibulum of the upper pole calyx. The masses were presumed to be inflammatory. The patient developed a severe stricture of the renal pelvis and complete occlusion of the upper pole calyx. This is an example of obliterative pyelitis, as described in the era before antibiotics were available.
