Applications of Bladder Ultrasonography. I. Bladder Content and Residue

Abstract

In reviewing our experience in the field of bladder ultrasonography, we conclude that this method is seldom used because its value has not been disseminated widely. Such a method is especially valuable in the investigation of infiltrative bladder tumors and the calculation of bladder volume. We herein report the results obtained in 100 patients whose bladder content has been calculated with the formula 12.56 times radius times height. We also outline the advantages of ultrasound over catheterization.
