膀胱腫瘍におけるBarium-Air Cystography

Abstract

Cystogram was made with use of BaSO4a nd air in thir t e en cases of bladder tumor. In nine cases the outline or surface of tumor was clearly delineated with an excellent contrast to the lumen of the bladder. Even in the small tumor in which ordinary cystogram failed to give any picture of tumor, barium-air contrast cystogram successfully demonstrated the contour of tumor. Size, shape, and roughness of the surface of tumor can be estimated on the cystogram as BaSO4 precipitates easily on the ulcerative surface of tumor. This method is contraindicated in case with vesicoureteral reflux, however, no serious complication is usually encountered.
