Abstract

Double-constrast and positive-contrast cystograms were performed in 12 dogs. After cystography, E. coli cystitis was induced in nine of the 12 dogs. The remaining three dogs were used as controls. Double contrast and positive-contrast cystograms were repeated threee, seven and 14 days later. During cystography, bladders were distended to mild, moderate, and complete degrees of distention. Mucosal irregularity decreased with increasing bladder distention and was more likely to be seen on double-contrast than on the positive-contrast cystogram. When seen on both types of studies, mucosal irregularity was more obvious on double-contrast than it was on the positive-contrast custogram. Bladder wall thickness decreased with increasing distention; in some dogs with mild cystitis, abnormal wall thickness was masked by complete bladder distention. Bladder wall thickness could be measured more often on double-contrast than on the positive contrast cystograms. Wall thickness measurments made on both types of studies were similar. It was concluded that lesions of mild to moderate cystitis may be missed when the bladder is completely distended, and that the double-contrast cystogram is more sensetive for evaluating mucosal margivation and bladder wall thickness than is the positive-contrast cystogram
