DOUBLE CONTRAST GAS BARIUM CYSTOGRAPHY IN THE ASSESSMENT OF DIVERTICULA OF THE BLADDER

¹ Professor and Chairman, Department of Radiology, Louisiana State University School of Medicine in Shreveport, Shreveport, Louisiana

Double contrast gas barium cystography is recommended for the assessment of diverticula arising from the bladder. The usefulness of the procedure for identification of the location of diverticula that cannot be visualized cystoscopically is emphasized. The method also aids to assess the contents of such diverticula, stones or tumors, particularly if massive bleeding at the time of cystoscopy prevents satisfactory cystoscopic visualization.

The remarkable lack of aggressiveness of 4 tumors arising from diverticula and failing to penetrate the thin muscularis of these diverticula is stressed in this series. A much higher cure rate of carcinoma arising from a diverticulum than from the bladder proper can therefore be expected and emphasizes the necessity of diagnosis of such lesions.
