OBSERVATION OF THE MUCOSAL FOLDS IN THE UPPER URINARY TRACT ON INTRAVENOUS PYELOGRAPHY

Abstract

The present paper describes a urographic observation of fine radiolucent and radiodense lines in the renal pelvis or ureter or both. When carefully looked for, the finding is not infrequent.
During the past 4.5 years, 193 patients had been seen who had striations on 3407 intravenous pyelographies, and the majority of the cases presented some form of urinary infection.
In five cases, the affected urinary tract was resected and its histology studied. In each case the mucosa showed inflammatory changes and vascular congestion.
The literatures were briefly reviewed and the roentgenologic differential diagnosis of the inflammatory mucosal folds and leukoplakia was discussed.
